Hello, I am thinking of connecting my KPA500 to a 240V outlet that is close to the shack that has a NEMA 10-30 receptacle. I'm soliciting advice on how to proceed.
As background, I am looking into this because the lights dim a bit when the amp is keyed down. It's a bit distracting and while I don't think the circuit is actually overloaded, it's definitely close to the limit. I was thinking of making a cable by modifying an IEC power cord (with C13 connector) by connecting the two wires to the two hots of a NEMA 10-30 plug, and ignoring the neutral plug AND ignoring the ground wire in the IEC power cord. A few questions about this approach: - Is it the correct way to wire the connectors together? - Is it dangerous in any way? - Is there anything that can be done to reduce/mitigate the danger (if any) other than having an electrician install a currently-up-to-code 240V circuit in the shack? - With respect to safety, assuming it is safe for the KPA500 would it be safe to run other amplifiers that require 240V? How would I determine this? It seems that clothes dryers that are connected via a NEMA 10-30 connector typically have the neutral pin connected to the chassis. Based on my research, the NEMA 10-30 connector was used widely before it was declared not up to code for new installations in 1996. Since many homes were built prior to 1996, I would imagine that others on the reflector might have encountered this sort of issue when dealing with 240V in the shack. Advice appreciated. 73, Matt NQ6N ______________________________________________________________ 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
