KPA-1500 Power Supply Cable Size

The 75 amp Powerpole connector is designed for 6, 8 or 10 AWG wire so you
might have problems squeezing a larger wire in. John KK9A [Elecraft] KPA-1500 Power Supply Cable Size Clay Autery KY5G at montac.com If it uses a 75 Amp PP connector, my inclination would be to use the 6AWG MINIMUM. I would be tempted to use the flexible welding cable lead stock in the largest gauge I could fit in the application space. I'd trim down the end of the conductor to JUST fit into the 75 AMP crimp contact. Then, I'd tine the trimmed down end to bond ALL the conductors together right at the end before I crimped/soldered. Then, I'd crimp/solder the terminal on making sure not to be sloppy and cause a fitment issue. If possible, I would put as many twists in the red/black leads between radio and power supply connection as possible.... I've not investigated the wiring yet, BUT, if there is a ground wire between the PA chassis and the PS chassis, I would integrate the ground wire into the power harness in a 3-wire bundle with all three wires as close to the same length and shinked into a single cable. But I'm nuts... <smile> > > On Sat, Jul 28, 2018 at 5:04 AM, Richard Thorne <rthorne at rthorne.net> wrote: > >> What gauge wire is used for the HV line between the power supply and amp? >> I'd like to build or source a shorter cable. >> >> Thanks >> >> Rich - N5ZC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I purchased 75 amp Anderson Powerpole connectors and #6 flex speaker
cable from Debco Electronics for my extension cable. #6 fit easily. I suspect even #4 would have fit, but I see no reason to get that large. -larry (K8UT) ------ Original Message ------ From: [hidden email] To: "'Elecraft Reflector'" <[hidden email]> Sent: 2018-07-28 15:21:03 Subject: [Elecraft] KPA-1500 Power Supply Cable Size >The 75 amp Powerpole connector is designed for 6, 8 or 10 AWG wire so >you >might have problems squeezing a larger wire in. > > >John KK9A > > >[Elecraft] KPA-1500 Power Supply Cable Size >Clay Autery KY5G at montac.com > >If it uses a 75 Amp PP connector, my inclination would be to use the >6AWG MINIMUM.

See my previous post.... teim down the end to fit the 75 amp crimp terminal.... tin the step point so that all strands are soldered together... <smile>.
In fact, I just did this today to get some #10 wire to fit a piggy- back spade connector that was for smaller wire... (all I had) Was making a dual power pole to 1/4" quick connector adapter with piggy back male quick connect.... to use on a Bioenno battery with 1/4" quick connect spade connectors.

Classic pissing contest about whose wire is better.
What is the maximum current draw for the amp? #6 AWG copper is rated at 101 amps for chassis wiring and 37 amps for power transmission, not this case. #6 will fit a 75 amp PP connector. (stick it in the hole squeeze it and solder it) and has a resistance per 1000 ft of 0.3951 Ohms. Let's figure the voltage drop. 10 foot zip cable (two conductors so use 20' in the formula) 50VDC @65 amps. Voltage drop equals .26V. The amp won't even notice it. If you bump the current draw up to the PP limit of 75 amps the Vdrop is 0.30V. #8 AWG copper is chassis rated for 73 amps and has a resistance per 1000 ft of 0.6282 Ohms.. Voltage drop = .41V People need bigger cable because?...Use what Elecraft uses, whatever that is, and be well. http://www.powerstream.com/Wire_Size.htm https://www.calculator.net/voltage-drop-calculator.html R.

Pissing contest? I was trying to be helpful by illustrating the possibilities.
I clearly pointed out that it wasn't necessary, but merely an option. How about you use whatever you want, and keep your negative opinions to yourself. Sincerely,Clay E.

It is good it will accept a larger conductor, especially for someone wanting to move their KPA1500 power supply further from the amp portion. I had a tough time installing 8 awg to the PowerPole 45 amp K3S connector which is designed for 10 awg max.
