And I couldn't really see those countries doing anything about it unless the US did something actually bad, which they wouldn't do IMHO. Was I being a pollyanna? How things change is up to every person in the community. Operators are an incredibly important part of the Internet ecosystem. Some questions you might want to ask yourself: 1. What is the current legal framework for the IANA functions contract? If you don't know it, it's a good time to learn, if you are interested. 2. How does it impact operators? 3. What do operators want out of the evolution that is likely to take place? Discussions are taking place now in a few fora, including on the IAB's internetgovtech mailing list[1], where the focus has largely been on protocol parameters, one of the IANA pillars. Olaf Kolkman has written a very interesting draft draft-iab-iana-framework[2] that gives you at least one view on how to think about the problem. The IETF has some draft principles that are being knocked around.[3] There is a separate 1net mailing list[4] in which mostly the ICANN component is being discussed. Also, there will be meetings, the ICANN one starting on Friday in Singapore, as but one example where this topic will be discussed in person. I'm going to hazard a guess that the RIRs will also be discussing this, both on lists and in person. Assuredly other governments are paying attention. While I speak only for myself in this email, I will also point out that Cisco did make a statement about the NTIA announcement.[5] So have others.

Get a short before the strip breaker and the main breaker trips before the wires can heat. There just aren't a whole lot of failure modes here that result in fire short of one or the other breaker failing. And that results in fire regardless of the amperage mismatch. The amount of misinformation in this thread is astonishing. This, by the way, is why you're allowed to plug that 22 gauge Christmas light wire into a 15 amp receptacle even though it can't handle 15 amps: the 3 amp fuse will blow if there's a short. Just don't plug in anything with lower-rated wire that doesn't have its own breaker or fuse. Regards, Bill Herrin Note that in those cases the fuse is in the plug; anywhere else wouldn't be ok. As small as 18AWG may be used for fixture wire on a 20A circuit, per 240.5(B)(2)(1). 2011 NEC article 210.23(A) permits 15A receptacles on 20A branch circuits; 30A branch circuits must use 30A receptacles. If the OP's 30A branch circuit has an L6-20R on it then this would be a violation; see NEC Table 210.24 for a summary of the code. 406.8 is the article requiring that cord caps (plugs) are not supposed to be interchangeable. Now, article 240.5 is the relevant article in the NEC. This can get a bit tricky to apply; if the PDU in question is *listed* for connection to a 30A circuit then that's OK (240.5(B)(1)); the individual fixture wires within the PDU for a 30A PDU can be as small as 14AWG as long as they're protected (240.5(B)(2)(4)), but field assembled extension cord sets for a 30A circuit would need 10AWG conductors, as they aren't covered by the exception in 240.5(B)(4) and thus fall under 240.5(A). It's definitely allowed to connect a 30A PDU with 10AWG conductors to a 30A branch circuit; anything else could be OK, depending upon the local authority having jurisdiction and its interpretation of the 240.5 exceptions, which aren't the clearest section of the NEC, IMO. And article 645, dealing with ITE rooms, only requires that cords be listed for use with IT equipment and be less than 4.5m in length. IMO, and my degree is in EE, it is possible to have a fault condition in a 12AWG cord that won't trip a 30A breaker but could cause a fire and be prior to the input breaker in the PDU. The OP appears to be doing the right thing and getting a 30A PDU.

In (all our) defense, lamp cord is the closest thing to conductors in free air that most people will ever run into, and although the insulation isn't high temperature stuff, the heat buildup isn't the same as a few dozen THHN conductors in EMT. If you want something that will make your head explode a little (until you think it through and realize that ampacity is just another way of expressing i^2r losses plus dissipation rate), read NEC table 630.11(A), and then 630.12(A) and noodle on just how skinny a wire you can use for hooking up a (home, low duty cycle) welder that's breakered at 50 amps. 12 AWG anyone? -r

This is not really a safe thing to do unless the adapter has a 20A circuit breaker as part of it, or if you change out the upstream circuit breaker from 30A to 20A (and hopefully clearly mark the outlet as such). If you're trying to go the other direction, plugging an L6-30P into an L6-20R 20 amp circuit, that I'd recommend against because it never fails that someone says hey, 30 amp power strip, let me plug some more stuff into it not realizing it's on a 20 amp breakered circuit, then all your stuff goes down while you try to find the facility staff to reset the breaker. Going this way is safe, but as you say, you can only draw 20A (actually, you can usually only draw a derated 80% of that, so 16A).

Customer Support Ticketing
Hey folks…. We need a new customer ticketing system and I’m looking for input. I am still working on a scope document on everything we want to do with the new system. The most common problem I run across is that a system is either built for enterprise internal IT helpdesk or it is built like a CRM sales tracking system. We are an ISP among other things and are looking for a powerful and yet reasonable cost system to answer email inquiries, allow customers to open tickets via portal, mobile support, escalation/SLA support, and several other things. Solarwinds NPM integration would be a huge bonus but not a deal breaker. If anyone has a system that they have integrated with Ivue from NISC (our billing platform) I would be really interested in hearing more as well. So my question is meant high level. For those folks that are ISP’s supporting business customers (including managed customers) along with residential eyeball traffic what system(s) do you use and what do you like/dislike? I’ve looked so far at WHD (Solarwinds product), OTRS, RT, RemedyForce, ZenDesk, HappyFox, Kayako and several others. All of them so far would require a fair amount of configuration or modifications based on our still developing wish list. Also worth noting is that we have no full time development staff so hoping to find something that has a lot of promise and then work with the vendor to evolve it into what we feel we need. **This is not an invitation for sales folks to call on me** Thanks, Paul

Re: Customer Support Ticketing
The advice I will share with you is as follows:- Take your wish list and divide it into Core Functions (need to have), Functions (want to have) and Functions (nice to have). Be prepared to compromise, the most troublesome area is going to be the Functions (want to have).. Many of us want to fit new software to existing processes, while forgetting that the existing processes were designed to deal with current systems/limitations. Most of this can be resolved by some other form of external process or procedure change , be it manual or some sort of external reference... I am not a big fan of software customization, creates challenge with updates upgrades, ( don't confuse software customization with software integration). Having said that, for us (we are an entity that is very much similar to what you have described in your email), we have been using Kayako. We found it to be very flexible for handling support tickets, email inquires and also a central repository for Alerts etc. We are now in the process of implementing a new Customer Billing package, (Freeside), which has RT integration, so we are most likely going to move a few of the mail queues to Freeside/RT, while leaving kayako to handle the other email queues. My point is, while it is nice to have a 'fully integrated' system, such a system starts to have it's shortcomings from day one... (e.g. if you tie it to your billing system, then what do you do with sales inquires ? you don't want to overload the system with junk.. or even system alert trouble tickets) Over the years we have found it more practical to develop some process to tie the info together in billing and ticketing system (we record ticket # in the billing system, as a ref. for related tickets), than try to do some sort of automation / customization. Of Course your mileage may vary.

RE: Customer Support Ticketing
Kayako is pretty reasonable with a few caveats. If you self host it, which I recommend from a security/supportability/customization standpoint, then you are also taking the trade off of dealing with upgrading it yourself, which is not always easy. Make use of their LoginShare functionality to offload authentication duties since their internal method is not particularly secure (unsalted SHA1). If you let it parse emails, with large attachments, you'll have to fine tune its memory allowance and how many emails it retrieves per attempt as well as how frequently it grabs them; it can use a lot of memory and it's not the fastest thing, so you don't want to have it happen to frequently where the prior job may still be running. The search functionality is absolutely horrible and has been for at least eight years now; it will turn up completely irrelevant tickets and rarely turns up the correct ones. If what you want to search for is in the ticket body rather than the private ticket notes, you do at least have the option of entering raw SQL LIKE arguments, so you can search for something like %parameter% and let MySQL do the work instead of Kayako, assuming your term is unique enough to find what you needed. If you need a better search of all fields, you'd have to write your own. I haven't personally used the Solarwinds product, but if it's like their others, the license fees will be outrageous, either now or they'll get you later, and their sales staff will bother you incessently with better and better short term promotions.

OP was talking about putting an L6-30P on a 20 amp appliance: a PDU that has its own 20 amp breaker. Big difference. If the PDU isn't listed for 30A then it's the essentially the same thing, safety-wise. Unless there is overcurrent protection at the source of the feed to the conductors of the flexible cord (240.21) that meets the ampacity of the conductors of said flexible cord, unless one of the exceptions of 240.5 apply, then it's a potentially unsafe condition (NEC doesn't directly apply to supply cords of appliances themselves; that's what the 'listing' is for from UL or similar; see http://ecmweb.com/code-basics/nec-rules-overcurrent-protection-equipment-and-conductors for more info, and see UL's FAQ entry for modifications to listed equipment at www.ul.com/global/eng/pages/offerings/perspectives/regulator/faq/). Just replacing an L6-20P with an L6-30P on a 20A-listed PDU would be unsafe and (IMO) unwise, since the breaker in the input of the PDU does not protect the flexible cord's conductors from internal overcurrent faults. A 20A listed PDU should have 20A overcurrent protection to the connected receptacle, in addition to any overcurrent protection internal to the PDU. A cord with a 20A ampacity may overheat significantly if it faults internally in such a way as to cause more than 20A, but less than 30A (or whatever overcurrent protection is in the branch circuit), to flow; there are numerous ways cords can fault in this manner. You could easily get a situation where the cord is partially faulted internally but the PDU's breaker doesn't detect it because the fault shunts current ahead of that breaker; again, not a dead short but still an overcurrent fault. I've seen this type of fault before, where the cord itself was shunting a few amps prior to the PDU input breaker (in this particular case the cord was damaged by lightning, even though the equipment to which it was connected still had power). But the other condition, where a 20A breaker is feeding a 30A PDU, could result in dropping power to the PDU but is not unsafe. I know that I wouldn't approve (in the NEC-speak sense of that word) of the use of any of these adapters or similar kludges in my data centers, as the insurance liability issues are potentially much more costly than just buying the right PDU or running a branch circuit with the correct overcurrent protection in the first place. It also depends a bit on exactly how the PDU is listed. You can look up the listing's details in the UL White Book (download link: http://www.ul.com/global/documents/offerings/perspectives/regulators/2013_WB_LINKED_FINAL.pdf ). But the final say rests with the authority having jurisdiction, AHJ in NEC-speak.

RE: L6-20P - L6-30R
I recently bought a UPS with a 30R plug on it, and sat and tried for about 20 minutes to plug it into what I thought was a 30 socket. It was, in fact, a 20. They're similar enough that if you're looking at the ends you might be convinced that someone has bent a one of the ends of the plug funny, but no amount of trying will make them fit.

Re: L6-20P - L6-30R
You probably should ask your facility operator or electrician what the requirements are (who, unlike most network engineers, is qualified to decide what to do), but it sounds like replacing the PDU is simple and easy, and unquestionably not a bad thing to do. Alternatively, you can replace the 30A circuit with a 20A one. I'm not an electrician, but I'll bet it's not much more complex or expensive than replacing a breaker and a receptacle, and I'd be shocked if it took more than an hour of a qualified person's time, and I suspect it would cost about the same for parts as building some sort of adaptor cord (and less if you the electrician has spare parts - he gets a 30A breaker and 30A socket in exchange for a 20A breaker and 20A socket). The added benefit of 20A, assuming your equipment power usage is low enough to use 20A, is that it's usually cheaper (sometimes significantly) if you're paying someone else for the power circuit each month.

RE: L6-20P - L6-30R
Just because you say the debate should be ended doesn't mean it's true, or that you are even correct. To end the debate, my staff master electrician says just replace the breaker. Your staff electrician missed half the answer, which would be to replace the breaker AND the receptacle. But you make sound as if the OP has that option readily available to him, and it's doesn't answer is original question. You can leave the outlet if you want or replace it too. Really, a mismatched outlet on a breaker size not intended for it? That seems like a good idea. Doesn't matter. The 30A circuit should be 10 gauge which is fine for 20amp. That part is correct. And to Jay: Network cables most certainly do carry power. No, they carry signal, which is considerably different - unless of course it is 802.1af.

[Whee.

Get real man. The NFPA thinks so. They also allow interoperability between a 20A T-slot receptacle and a 15A plug (so that a 2-15P can work in a T-slot 2-20R, or a 5-15P can work in a 5-20R, etc). Things are different above 20A, at least in the NFPA's view. NFPA 75 is interesting reading, especially in those sections where its committee and the NFPA 70 committee seem to see things differently. However, my SOP is to use no smaller than 16AWG for a 5-15P or 6-15P (with a 14AWG preference), and no smaller than 12AWG for 20A use, etc, unless protected by suitable overcurrent devices (for 18AWG, that's 7A, and for 16AWG that's 10A, so a power strip with a 10A breaker or a PDU with a individual 10A breakers is fine for use with 16AWG power cords). I do have an EE background and degree, and so I do tend to be very conservative in those things. I have seen the results of pinched 18AWG zipcord in a 5-15R, and it's not pretty. The 22AWG Christmas lights get away with it by having overcurrent protection in the plugs. You got two things right: The NEC (and related fire codes) don't apply to supply cords of appliances in circumstances such as OP's PDU. The modification cancels the UL certification. If you have an external requirement to use only UL certified components then you can't make any modifications no matter how obviously safe they are.By the way, you either don't have that requirement or you're breaking it. Your custom network cables are not UL certified. Here's the bottom line, at least in my data centers: if it could be considered questionable by the insurers (that's where UL got its start) then it's not likely to happen. Modifying a piece of utilization equipment with a UL QPQY listing is likely to be considered questionable. Now, network cable installation is covered by the NEC in article 800, which got some revisions in 2011, and the class 2 and class 3 cables used are also covered, in articles 725 (fiber is covered by article 770, and ITE rooms by article 645). The major theme there is reduction in spread of products of combustion, and the UL DUZX listing reflects that purpose. Yes, listed cables are required by code when part of the premises wiring, but putting a listed connector on listed cable is within the listing. Further, 802.3af and even 802.3at are considered Class 2 power limited sources under article 725 of the NEC (that is, there's not enough available power to initiate combustion). So, sure, I can still use custom network cabling and stay within using only listed items.

The limits for Class 2 and 3 circuits are found in Chapter 9, Table 11 (A and B), of the NEC (Table 11(B) for DC circuits, and for a power source of 30 to 60 volts a Class 2 circuit can have, for a 44VDC supply power, up to 3.4A available (a max nameplate rating of 100VA).

However highly unlikely to be code-worthy of slapping on a 30A breaker in place of a 20. 10-20 CCCs in a raceway or cable is a 50% derating, so if those conductors were for 20A branch circuits it would have to be 10AWG, not 12 since with 10AWG you're derating from 40A. But the max protective device on 10AWG is 30A unless permitted by 240.4. Even 7-9 CCCs in a raceway or cable derates 10AWG to 28A (70%), so while still suitable for a 20A breaker it's not for 30A.

It's not the conductor that you're derating; it's the breaker. Per NEC Table 310.16, ampacity of #12 copper THHN/THWN2 (which is almost certainly what you're pulling) with 3 conductors in a conduit is 30 amps. Refer to Table 310.15(B)(2)(a) for derating of more than 3 current-carrying conductors in a conduit. 4-6 is 80%, 7-9 is 70%. Plenty good for 20 amps for any conceivable number of conductors in a datacenter whip. Thermal breakers are typically deployed in an 80% application for continuous loads, per NEC 384-16(c). See the references to 125% of continuous load, which of course is the reciprocal of 80%. http://cliffordpower.com/wp/wp-content/uploads/2010/08/CPS_info_sheet_37_CB_80_versus_100.pdf -r

We need a new customer ticketing system and I’m looking for input. I am still working on a scope document on everything we want to do with the new system. The most common problem I run across is that a system is either built for enterprise internal IT helpdesk or it is built like a CRM sales tracking system. We are an ISP among other things and are looking for a powerful and yet reasonable cost system to answer email inquiries, allow customers to open tickets via portal, mobile support, escalation/SLA support, and several other things. Solarwinds NPM integration would be a huge bonus but not a deal breaker. If anyone has a system that they have integrated with Ivue from NISC (our billing platform) I would be really interested in hearing more as well. So my question is meant high level. For those folks that are ISP’s supporting business customers (including managed customers) along with residential eyeball traffic what system(s) do you use and what do you like/dislike? I’ve looked so far at WHD (Solarwinds product), OTRS, RT, RemedyForce, ZenDesk, HappyFox, Kayako and several others. All of them so far would require a fair amount of configuration or modifications based on our still developing wish list. Also worth noting is that we have no full time development staff so hoping to find something that has a lot of promise and then work with the vendor to evolve it into what we feel we need. **This is not an invitation for sales folks to call on me** Thanks, Paul

It has a 5-15P on the end of it, which could be plugged into an outlet rated for 20 amps (5-20R), with 16 gauge lamp cord rated for 10 amps or less. Mine all seem to be NEMA 1-15P, some (most?) with 18 AWG wire. Have I been shortchanged? :) I wrote that too fast, you are absolutely right. But my point remains. Appliance/load wire size is often, and many times smaller than the ampacity of the circuit. Heck, how many times have you plugged in a 14 gauge extension cord to a 5-20R? I believe the thinking behind the standards is that the breaker is sized to protect the wiring to the receptacle or fixture. After that you are on your own. It is always safe to demand less current than the circuit is designed to provide. It is never save to deform connectors. Changing a receptacle to one of a lower capacity is safe, if confusing to those who follow you. If I operated a facility I would offer short adapters cords rather that changing the receptacle. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.

No, they carry signal, which is considerably different - unless of course it is 802.1af. That's what he meant, yes, and a couple other people made the point as well. 1af is 48VDC *precisely* to make it remain Low Voltage, which takes it outside the realm of NEC[1], and hence, UL.

It is even*possible*, though unlikely, that if you did so, you wouldn't have to derate it to 80%. I would have to reread the Code to be sure. Well, I'd say it's pretty likely. However highly unlikely to be code-worthy of slapping on a 30A breaker in place of a 20. Well, the situation were were discussing was replacing 30A CB -- 10 AWG -- L6-30 with 20A CB -- 10 AWG -- L6-20 and as I was reminded, you'd still have to derate that unless the CB was magnetic. And you can't leave the breaker at 30, cause then the attached 20A single device isn't protected properly by it. So I was worng on the derating. Cheers, -- jra -- Jay R.
