How to remove ground pin on power cable

From some posts here, apparently many homes continue to be grounded via the water line.

This hasn't been acceptable ( up to code ) in decades. I mean, there's no requirement to fix this, generally, but you may no longer rely on copper pipes for new construction and upgrades.  You MUST use grounding rods (sometimes more than 2, depends on soil conditions) for the electrical ground and they must connect to the neutral only at the service entrance. Any sub panels must maintain the ground/neutral separation.

There are some requirements to ground copper pipes, which I forget why, but you don't use them as electrical safety grounds. Not only are the connections iffy, but with modern water pipes using mostly plastic it is quite easy to find an older home which has plastic in the middle.

There always comes a point in every discussion of electricity where the common sense ends and Nervous Nancy and the Technobabbler’s take over. This is it. The end of the common sense. And now, without further ado, performing twenty five shows a day for endless nights only, our encore presentation of Nervous Nancy and the Technobabblers!

That's some kwisatz haderach level presience there, fellas.

Which like I said, ignorance and irrational fear abounds. Now you know we have two grounds, the utility ground everything has plus the redundant earth ground they made us add.

Like most everything, mc is ignorant on electrical wiring. There is one ground and that is the utility neutral. The Earth safety [ground rod, Ufer, copper pipe] is connected to it in the event lightning hits the electrical service. The Earth safety takes the current to earth, not the neutral.

The Earth safety on equipment is to prevent the chassis becoming live in the event of accident or failure.

Nervous Nanny:

1. remove safety ground pin
2. slide heavy amp w captive cord into rack
3. pinch cable between amp and rack, cut through insulation to hot lead
4. drop amp
5. cut off toe

I see SatTV and Cable 'grounded' to hose bibs on houses plumbed with PEX.

Like most everything, mc is ignorant on electrical wiring.

+1. Or as Mark Twain famously said, “What gets us into trouble is not what we don't know. It's what we know for sure that just ain't so.”
