You know what happens when we were recording and we detected a faulty power cord? We replaced it then shut the studio down for 2 weeks.
Sorry bit of professional humor. We replaced it. No one noticed. Usually it was replaced due to damage/safety not actually failing and we replaced with new. Generally heavy duty as they took a lot of abuse. Then again could be just that the artist forgot the power cord to their amp, synth, etc. Never once do I remember them insisting they had to run/fly home and get their own cord (or let it sit for several days).
Now obviously recording and playback are not the same but the people who make your music don’t fret over this, don’t even give it a thought actually (except hum and noise). For live recordings the equipment including orders of magnitude more sensitive microphone cables were probably set up that day or if lucky the day before and no one gave any thought to the power cords on mic preamps, mixer boards, amps, etc.
Oh, contacts ... That's where problems existed most of the time. Contact cleaner/enhancer is your friend and sometimes tools to fix a bent pin.
