Re: [Elecraft] KPA-1500 Power Supply Cable Size
WHICH is why I detailed in the VERY beginning on this thread how to make the longer cable using 4AWG (or larger if desired). The ONLY place the cable would not be the larger gauge would be in the crimp terminal...

Re: [Elecraft] KPA-1500 Power Supply Cable Size
I'm missing something here!I keep seeing the question being asked, " What size cable is the power cord?" How about employing the KISS theory. Would it not make sense to make up an extension cord with a length to the approximate desired location from the power source? Such an extension would be fitted with proper receptacle as required by code,and is capable of at least twice the Amperage required by the KPA1500. Milvereton /W9MMS.

Re: [Elecraft] KPA-1500 Power Supply Cable Size
Points to consider. A legal limit amp dissipates ~1kW of heat. Small compact amps must provide the same heat dissipation as physically large amps. Thus airflow must increase in order to cool the components in a physically small case amp. Physically large amps have more room and slower airflow with the same cooling capacity. Slower air makes for less turbulence and equally less noise.

Re: [Elecraft] KPA-1500 Power Supply Cable Size
Jim Brown is on the National Electrical Code Committee, so he knows what he is saying and I would trust his opinion 100%! I guess my thought on any remote wiring is, if your really going to go through all the effort to do the project, then do it with materials, that you know when you purchase them are going to work for the duration of the installation, and provide you a reliable and safe installation. Cost should not be your only consideration. I have never seen any detailed specifications on speaker wire, when I have bought it to wire up my audio system. However, I knew that I was using it to wire up speakers, and the speakers were not a long distance from the amplifier. If the remote run is long, voltage drop in the cable is very critical. You also should consider protecting the wiring, so you may need to think of using conduit or some type of protected raceway as having wires carrying 60V in the open is also not a good idea. I think that considering diesel locomotive wire or similar flexible cable would be a good solution. It all depends on how far away the remote supply is located from the main amplifier and where it is being routed to the final destination. Unfortunately, I have seen people try to use speaker wire or lamp cord to do provide power in crazy ways. One guy I remember years ago was a recent immigrant from Eastern Europe with no electrical knowledge although he was an engineer. He wired his entire basement with speaker wire. Of course, I politely told him that was not a good idea, and that it was against the local and National Electrical Code to install. His initial response was that he thought is was a lot easier to install than the solid wire cable called Romex.

Re: [Elecraft] KPA-1500 Power Supply Cable Size
One of previous posts recommended using speaker wire for the remote connection of the KPA-1500 amplifier to the KPA-1500 power supply. Speaker wire is made for speaker systems. Although it may look like "lamp cord" it is not listed for use to wire up a lamp. You should buy rated "lamp cord" for that purpose. I think the same applies for dc wiring. I am not the code inspector for anyone, so do what you want, but if I had a long remote power supply feed, it would be wired with the proper size cable rated for the purpose. I suppose one idea could be to splice the larger size cable required for the longer distance to the Elecraft supplied cable at the termination end of the amplifier. The power supply protection protects the smaller Elecraft wire as designed, so going back to it at the very end is not an issue. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
