Can anybody help me on how to determine the amount of clean (as opposed to noisy/damaging power that I can get on a 20Amp circuit in a 30 year old typical Japanese home? I have my home PC and an air conditioner on the same circuit, and after 3 years, the PC now crashes regularly on power issues. I suspect that the compressor motor kicking on and off sends a surge and has slowly been damaging the PC over time. The only way that I could actually look myself would be to put an oscilloscope on the circuit.. and I don't have one… thanks!
