I have something I want to hook up in a room but I have no outlets with three hole sin that room, I know that is there for a reason though, grounding I believe. What is my risk if I break that off?

while breaking off it could fly up and impale your eye

get an adapter that you can attach to the wall. they have a small loop at the bottom that the wall plate screw goes through

edit for slowness fail :(

What's the device?

The ground is usually there a safety, in case some wiring fault should cause the hot wire to contact something's metal chassis. If that happens, and you happen to touch the case while grounded, you get an instant and intimate understanding the joys of 120VAC@60Hz.

Some things will also use the ground for surge protection, as a path for the excess power.

I think there are adapters. I would go with that instead.

this, or just get a three-pronged outlet at Home Depot or Lowes. They're like...80 cents or something, and super easy to replace. hell, you might even be able to actually ground the outlet, if you know what you're doing...

I would not do that. Yes its the ground and its there for YOUR safety not the tool or item you are plugging in.

What you should do is drill the 3rd hole into your outlet so that all future appliances and electronics are guaranteed to fit. :sneaky:

Most of the time it's for safety, other times it can produce "interesting" results.

Example:
When I moved into my house I didn't have any grounds, even though I had a lot of 3 prong outlets. When I hooked up my LCD TV my cable was flaky. And there was another side effect, I got zapped every time I touched the outside connector. You know, the one that is supposed to be ground. Inside the TV's power supply there are some caps that go between the line, neutral, and ground. This is a common and fair design. When it's not grounded, it puts the ground at approximately 60VAC (I measured 70...) due to leakage currents and the like. Thus, my LCD TV caused the shield on the coax, which happens to be ground, to be the ground. And this ground isn't a good ground like I needed it to be. So the net result... I got shocked every time I messed with the coax until I just used a pair of rabbit ears with that TV.

I want him to do it and see what his 'on my way to the hospital' thread turns out like

I had an arcade machine that was wired wrong and had the ground plug wired to the neutral line. Good grounding can be a lifesaver. If you absolutely have to plug a device with a ground prong into an ungrounded outlet, get one of the adapters mentioned above and screw the lug at the bottom into the faceplate of your outlet, it should give you some protection. Also, they are like $0.50 at home depot or walmart.

Better not be, if you're meeting code.

Ground and Neutral ARE bonded together at the electrical panel to meet code. There should also be a ground rod outside that the ground is bonded to.

Perhaps you were thinking he meant bonded together somewhere else? That would be wrong.
