Electrical Help - Stove tripping breaker *CONCLUSION*

[mike31154]

Yep, the two 40s will be for the stove, two hot leads (black & red) with a single neutral (white) and of course ground (green or bare). Not sure why they build these monsters with 15s at either end, my 30 amp breaker for the Electric Dryer is the same idea. The reason the two 40s are tied together is that if there is a fault in either of the hot lines to the stove, both breakers will be tripped disabling all circuits to the stove. This is for safety reasons obviously. The two 15s are I guess just nice and convenient, but have nothing to do with the stove circuit.

With all 3 wire circuits, 2 hots and a neutral, the neutral needs to carry the return current for both hot wires, so you might want to double check that all connections are tight, particularly the neutral. What size is your service (main breaker) 100 amps or higher?

I replaced the breakers today and reseated the stove plug into the wall and still the 40 amp breakers trip as soon as they are reset or the master(100 amps) trips. Unless there is a wiring fault in the walls somewhere I have to suspect the range unit itself, a new one arrives Friday. Thanks for the advice.

I have a gas range so do not have the large four prong receptacle you will for an electric range. I do however have an electric dryer and I suspect the wall receptacle for that is much the same. If so, make sure the breaker for the stove is OFF and open up the wall receptacle for the stove if you can. I strongly suspect the wiring is held on by screw terminals inside there. Check those to ensure they're tight, nothing to lose here as long as you make sure the power is off. There's not much that can go wrong with wiring inside the wall unless it's been overheated or it's been damaged through some careless renovation. The connection points at the breaker and the plug are the weak spots in any wiring circuit. Good luck, I hope the new range solves the problem, but if it's just a loose connection, that's a large investment, although sounds like a new range is a good idea anyhow if two coils have gone.

Tonight I flipped the breakers back on with the stove unplugged and they did not trip so the last piece before the range arrives is to inspect that wall socket as described. Thanks all.

Problem is in the stove
