Audioengr, if I may sidebar and ask a few general questions about things electrical:
1. I current have a 115 volt 20 amp dedicated circuit to my amplifier and the ground has been lifted. I have the schematic and instructions on how to convert my amp to 230 volts. If I install the proper 20 amp duel circuit at the service panel and connect my rewired 230 volt amplifier by simply running two leads (using my currently installed 10/2 romex and obviously from opposing sides at at the service panel), would I need a ground? I know I should always have a ground but I am not using one right now. But all's I need for 230 volts is two 115v lines from opposing phases?
2. If your answer to number one is yes, then why does a 20 amp or 30 amp cooktop or oven have two leads, 1 neutral, in addition to the ground? What's with the second lead in these appliances? Or is it the neutral I should be asking about?
3. You say that the neutral contains the return current as I've heard this many times. But why is it that I can touch my neutral bus in the service panel and not feel a thing? What is different about 'return current'?
