Range ckt is 3 wire but extened with new 4 wire ...GROUNDING?

[Finite10]

Is it legal to extend a range circuit that is existing 3 wire by using new 4 wire with ground?

250.140 Exception doesn't say you can alter or extend from a non-grounding cable using a 4 wire grounding cable to another location - using the old range recept. box as a J-box.

I would say no, it's not legal. Besides what you mentioned, because it' s decieving

Thanks Buck. The guy just felt stuck- he said he couldn't find 3-wire #6 Al cable and walls/ceiling would need to be opened up to fish new cable back to the new panel - - the owner or GC likely didn't want to go for that.

He left the bare ground coiled in the new box - so the deceiving part is that the next owner/electrician will see a ground and hook his new range up with a shiny new 4-wire recept and cord. Probably not put the bonding jumper in. Then the frame could be a death trap because it's not even connected to the grounded conductor.

Do I have that right?

You have it right. If they were just changing out ranges then they could have kept the three wire. But moving the circuit. to a new location would require a 4 wire taken all the way back to the panel. Regardless of what the GC or owner wanted.

Strange, isn't it, how when plumbing fixtures are moved to another area of the home, ceilings and walls are easy to open up, but when electrical appliances are moved, the drywall suddenly becomes almost impossible to cut!

That happens to you too ??? I thought that only happened here in NJ.:grin:
