Re: [Elecraft] Powerpoles (again)

I always used Molex connectors, they seem to work well. I switched to APP's when it seemed everyone was, I have the WMR crimper and haven't had any problems but then, I don't move my radio around much. I'm sort of with Joe for higher current stuff ... terminals and screws. I know -- KID:

I only have power-pole's on my K3/10 and KXPA-100. I installed a power-pole on the CCI 140w linear I built, but would not do it a second time. None of these power-pole will stay seated if equipment is physically moved. I very much like the power connectors used by DEMI on their

[New subject in an attempt to avoid topic drift.] Several people have said that they don't like Powerpole power connectors. I like them quite a bit, given their flexibility and ease of use. I will note that the proximate problem that started this thread again was a bad solder joint, which

[Elecraft] PowerPoles

IMHO, there are only two kinds of Powerpoles, those that have already fallen out and those that are going to fall out soon. I have had the PowerPoles on my K3 become partially unmated and causing intermittent operation while messing around with the cables behind the rig. Retention force is

[Elecraft] PowerPoles

There are two problems with the PowerPoles: 1. The contact pulls out of the housing due to improper assembly. 2. The completed plug assembly (contacts and housings) pulls out of the matching assembly on back of the K3. Most people having a problem don't specify which problem they're

Re: [Elecraft] PowerPoles s way to prevent from plugging them in wrong

Heck, it is an even better plan to just turn off the power supply before making any such connection, whether it is a computer, radio, or accessory. But, shoot, this could happen to anyone in a hurry or in a moment's distraction. My most frequent connectivity faux pas is to confuse the

Re: [Elecraft] PowerPoles

It appears this thread has broken into several topics based upon the readers interpretation of the problem. Let's break it into 4 categories: 1. Connecting the wire to the contact (crimping or soldering) 2. Inserting the contact into the connector body 3. Mating two connector bodies to form a

Re: [Elecraft] PowerPoles

Thanks, that does clear things up. How about using very flexible stranded power wire? Powerwerx has spools of it, but I'm sure it is available elsewhere. http://www.powerwerx.com/wire-cable/power-wire-automotive.html wunder K6WRU On Jun 17, 2013, at 8:53 AM, Roger D Johnson wrote: It

Re: [Elecraft] PowerPoles

I recently built some 75A powerpole connectors and bought the bonded version. Had some difficulty getting a good insertion of the pins. I wanted to use No. 10 wire and could not get a decent crimp that would allow insertion (granted I do not have the proper crimper). I finally resorted to

Re: [Elecraft] PowerPoles

Roger . . . K3 serial number 21 was received in kit-form on October 27, 2007, with the power pole connector firmly attached to the RF Board (by the board manufacturer) but with one of the wires going to one side of the power pole just barely long enough to reach the connector. This meant that

Re: [Elecraft] PowerPoles

If you do not have a proper crimping tool, solder the APP contacts. Soldering has its downside if used in high vibration environments (the wire will break where the wicked solder ends), but for applications where the wire is not subjected to vibration, soldering is better than connections made

Re: [Elecraft] PowerPoles

Don, I tried that, first. I trust solder joints to maintain low resistance better than crimping in some atmospheres. But the large wire sitting in the connector with the crimp wings sticking straight up would not fit into the square hole of the power pole. I wasted one connector in

Re: [Elecraft] PowerPoles

Ed, If you are using #10 wire, I would rate that at 30 amps. That gauge wire will just barely fit into the 30 amp APP connectors, and I prefer to use the 45 amp connectors for #10 wire. I think your use of the 75 amp APP connectors is overkill. Yes, the proper crimping tool is mandatory

Re: [Elecraft] PowerPoles

The Powerwerx #10 equivalent wire is 392 strands of #36 copper, so it is much more flexible than regular stranded wire. Their #8 equivalent is 616 strands of #36. wunder K6WRU On Jun 17, 2013, at 5:40 PM, Bill Frantz wrote: I have some #12 stranded wire that came from Radio Shack in my junk

Re: [Elecraft] PowerPoles

FWIW - My memory of the National Electrical Code is that soldering is permitted for low current connections (up to 20A), but higher currents require wire nuts or some other approved connection. The code authorities worry that a bad connection will got hot and melt the solder letting it flow

If they are coming apart easily then you are not building them right. I have done thousands and learned a few things in the process. (I make and sell cables at hamfests.) They should take at least 10 pounds of pressure to pull them apart. It should take enough pressure to connect them that you
