How to remove ground pin on power cable

Mickeyb, if the panel and meter are grounded to two ground rods (NEC code currently, I believe) what is the additional grounding to the water line?? I’m curious.

I can think of 101 ways by which a chassis can become live.

His advice could be L E T H A L !!

@nemesis18 - do you have the sub plugged into a different circuit? Is it on the other leg of the power service?

Are you sure you need it plugged into a different circuit?
See https://forum.audiogon.com/discussions/should-subwoofer-be-plugged-into-same-circuit/post?highlight=breaker&postid=1843996#1843996 - A/C circuits can supply several multiples of rated breaker capacity for brief instances ala musical peaks. If your system is properly configured so the sub frequencies are not in the mains, they do not require the power.

DBA? Then use an isolation transformer. The life you save maybe your own!!!

I can only think of two: Frankenstein. Frank N Furter. 99 still to go. You got me.

Don’t cut the grounding 3rd pin off the male plug; it voids a warranty if it’s still in effect. Same for any DIY ’surgery’ to defeat it...
Besides, it’s likely there for a good reason. Like keeping your hide intact.

Instead, try a simple test 1st.
Insert a 3>2 ’cheater plug’ that comes with the separate ground wire.
(These are also colloquially referred to as a ’dead man plug’.....Gee, I wonder why.....}.

Turn your unit back on. Listen for annoying noise.
If it’s gone, wonderful.
If not, problem is elsewhere.

Bonus points and curiosity cure: Ground wire to the central screw that holds the cover plate of the wall box. Hum returns, Bingo.  Hum still exists....Well, fook....*L*

I had a similar hum issue a while back.....had nothing to due with the AC lines....faulty interconnect RCA cable....took a while to find That...
