You are right, Steve, it really doesn't matter as far as the operation of the KPA500 is concerned. However, 240VAC service is convenient for any high-current device because it requires only half the current of 120V. That means less line voltage droop under full load, particularly if your outlet is some distance from the breaker panel, and greater load capacity for the circuit overall.
Europe, and I guess much of the world, uses 240V as the standard household mains voltage. As our electrical demands increase, we just might make that change here in the USA one day, just as we changed from 6V to 12V for automotive electrical systems decades ago.

I found this thread interesting as I had 220VAC installed when I built my house. I hope to have a KPA500 one day soon. So my question is, what are the advantages then to using 220VAC over 110VAC in this case, if any? It sounds like it really doesn't matter. 73, Steve WU9B ______________________________________________________________ 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 ______________________________________________________________ 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
