Electrically, it's the same, but mechanically, it's quite different. A dryer receptacle won't see as much use as a regular receptacl, therefore less likely to have a connection break or come loose.

Go back and have another look. The question was asked "How is this different from jumping the neutral to ground on a 120 volt 15 amp receptacle?"

My answer is that it isn't different electrically.

You're not allowed to do that with a 120V 15A receptacle, but you are allowed to bond neutral to ground for a 240V 30A dryer feed.

That's not the law elsewhere.

When someone buys a dryer they pay for the cord kit. When the dryer is delivered, the driver installs either a 4 prong or 3 prong cord to match the receptacle that the customer has. The dryer comes equipped from the factory with a bonding jumper for the express purpose of bonding neutral to ground when using a 3 wire cord. I am sure that you have seen that in the dryer's instruction manual.

It's perfectly code compliant and within the dryer's listing.

what's with the 10-2? as others have mentioned, that's never been legal for dryer receptacle

I plead ignorance. My bad.

I probably shouldnít have said what you quoted me saying. As I mentioned later in the thread, I donít really install three prong outlets at all. The situation today was very uncommon.

The NEC allows that? That would not fly here.

It did allow it. I think it was the 1993 or 1996 NEC that nixed it. You can still repair existing installs.

Here if you touch an old installation you must follow new code. You can replace a broken outlet, but alter the wiring at all, even if you only want to move it an inch, it must be to new code.

The bond is typically done in the dryer itself, read a post 46 for the explanation.

I’ve done a lot of work in older houses here and never seen a three prong dryer outlet.

It's very common here.

I don't know why they allowed neutral to be bonded to ground in dryers/ranges. I agree with the others who say that it's not a good idea. Just like I think it's silly to allow parallel paths in the service entrance, and I support the Canadian code change to disallow that.

Maybe next time carry a 3 wire dryer outlet, and a 3 wire cord to match, make the bond in the dryer where it's supposed to be, and call it a day.
