Hello All, I'd like to wire up a plug on my workbench for working on amplifiers requiring 234/240V. Currently, there is a second dryer in place where I had planned to put the new outlet for 240V. I measured the voltage on the plug, and it's about 250V. Is there anything I have to do to drop the voltage down to 240V? Or am I able to install the plug without having to worry about the voltage difference? BTW, the amp I'm working on is an Amp Supply LK-500NTC wired for 234V.
