Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Two more comments: My station runs on an Astron 50M which I run about 14-foot of #4 welding wire to the master fuse (30A) and my power distribution strips. I see about 13.7v at the fuse. My 150w 2m amp gets about 13.3v under load. I ran about 35-feet of No.8-4 wire from my ac service to a

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

I have the resistance chart for various wire size but find that the voltage drop is usually more than ohms law predicts so I go up one size just for insurance. I included 4-foot No.10 Red/Black zip wire (from Powerwerx) with each of my 2M80 amplifiers which typically draw 15 amps key-down CW

Well, again, you have to define terms... "good engineering practice". Depends on how you define good... I am known far and wide for my incessant "over-engineering". I don't consider it over-engineering. I am always considering additional factors in my designs beyond IMMEDIATE cost. Cost for

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

The number of tragedies in my life suggest otherwise, but in this case, I must live a charmed life. I have never had RFI issues while using zip cord for speaker wiring in and around my ham shack. I have used the red/black stuff for DC wiring but lately I'm using 10 AWG wire made for

No Rick, they have developed a new plating process [Cu on Cu] that makes 12 ga wire perform like 10 ga wire. Now, if you wanted to use it for speaker wire, you would need yet another plating to prevent audio distortion and achieve the highest fidelity. That makes it more expensive. At least

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Guy, I am intimately aware of the code... I started out with a 40 Amp breaker at the service to the sub... I changed it to a 60Amp to "match" the 6AWG run... I would never install anything that was not up to code or use non-UL materials... And I always have my work double-checked by a

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

If the feed to the sub-panel has 60 amp breakers in the main panel, then #6 AWG feed to the sub-panel is required by the NEC code. That you estimate at this time you do not ever use more than 20 amps out of the sub-panel has no bearing on the ampacity requirement for the sub-panel. A subsequent

I'm making up a 20' cord to go from my car battery to any given picnic table for portable ops so 10 gauge would probably be appropriate when I want to go QRO. Yes someday I'll get a deep cycle and/or solar panel and someday later I'll put it all in an RV but for now I just want to go to the

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Over the years, I've bought some of the red/black zip cord at hamfests. While I have not measured any of it with a micrometer, my strong impression has been that it IS smaller than labeled. More to the point -- zip cord is TERRIBLE cable for loudspeaker wiring because it has very poor RF

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

How do you define "necessary". Paraphrasing K9YC, Jim "Big wire is your friend". I agree... I typically use wire at least 2 sizes larger than "required" Often the wire size is determined by how big of a wire I can FIT in the application and how much money I can part with at the time.

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Well, I don't use "zip wire" for anything anymore... But if you want a good selection of wire at reasonable prices, and great quality... http://wesbellwireandcable.com/index.html I've bought by the foot and by the spool from these folks. Tell Matt I sent you. :) I suggest using 10 GA

“Is this becoming common practice or is wire going the way of 2X4 lumber?” “Bad analogy. The 2 X 4 inch measurement of a piece of construction lumber is before planning, or rough cut lumber. The finished dimension is more like 3½ X 1½ which hasn't changed.” Not so bad an analogy. A

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Depends on the run length and the voltage drop you are willing to tolerate. 10’ of 10 gauge for 13.8 VDC @ 20A has a drop to 13.4V vs a drop to 13.16 for 12 gauge. Source: http://www.calculator.net/voltage-drop-calculator.html Joe KO8V > On Aug 11, 2016, at 10:43 AM, Ronnie Hull

Re: [Elecraft] [OT] Zip Wire Misrepresentation?

Ronnie, It "all depends" I use 12 gauge myself, but the runs are less than 6 feet. For longer power cables, I would use 10 gauge or larger. #10 is .000999 ohms per foot #12 is .001588 ohms per foot. For 12 feet of conductor (yes, you have to count the resistance both directions) - at 18 amps

I just bought 20' of what was supposed to be 10GA zip wire from that auction site. It is clearly marked as "Audiopipe 10 Gauge speaker cable". The conductor is actually 12GA at best. Is this becoming common practice or is wire going the way of 2X4 lumber? Suggestions for a reputable source of
