    I've answered this question before. The best solution (and possibly the only legal solution) is to install a panel with a shunt trip main breaker. Forget the C25DND330. It is not going to be able to handle the amps. It's just a regular contactor. Sorry, but if you need a schematic for it you shouldn't be working with it in the first place. I strongly recommend calling a qualified licensed electrician.

    Sorry, but as a licenced electrician, I'm not going to tell you how to jerry rig a fire protection system that should have been installed with a shut trip main breaker in the first place. I seriously doubt that anyone else will either. If you want to know how to hook up a shunt trip main breaker panel, I'll be glad to help.

SOURCE: 20 AMP Cutler Hammer CH GFI wont fit in the breaker box

It will fit, the extra bump out on the back makes it a bit harder to hook the back locking tab before you push it on the bussing. Also, make sure no wires are in the way obstructing the bump out since it hangs out further than the standard breakers. The most common problem is the bump out making it hard to hook the locking tab onto the outer rail. Make sure the breaker is in the off position, then try holding it more flat as you insert it keeping it close to the bussing. This will help keep the extra bump out from obstructing the locking tab from hooking the back rail. Once it's hooked on the back rail you can push it on the bussing like normal.

Smells electrical when running

Unless it is very new, this would indicate some of the wiring is getting too hot. Since stoves are not normally wired through a safety switch, get it checked by an appliance electrician. You do not want a fire.

How do I install a 220 volt outlet using existing wiring?

I would recommend getting an electrician. If you chose not to any mistakes you make can be a safety hazard and possibly kill somebody.

In this area we are required to use a 4 wire connection; Phase, Phase, Neutral (bare or white in the US), Earth (green in the US). You are missing the Earth connection and will need to run a wire back to your electrical panel and connect to the earth bus. Earth and Neutral are connected together at one point in your home. In older systems the Neutral was used for the earth connection as well, this is dangerous if a fault occurs. The Earth may also be called ground as could the Neutral but they are different even though they are connected connected together at one point in your system. If you have an older electrical system and do not have the appropriate Earth connections I would highly recommend hiring an electrician, electricity can cause fires and kill.

I have a new furnace and the breaker keeps tripping (20/30). It is a bryant westinghouse box. I think 200 amphes

1) You got a FIRE truck coming.

2) Wire is too small.
Problem is NOT circuit breaker.

3) Both 240Volt appliances on same breaker is a hazard, especially if space available in 200 amp service panel for more breakers.

4) Usually each 240V appliance has separate breaker.

5) Circuit breaker trips because of High heat on the wire.
If wire gets hot, it will start a fire inside the wall.

Electric code requires wire-size match breaker-size.

6) If you put larger amp breaker on same wire that is getting hot, then wire will get hotter.
Result: FIRE truck middle of night with folks jumping out window in glass-cut bare run across yard.

7) Each appliance has volts and watt rating on label.
EVERY appliance has label.

8) For example stove might be rated 8000 watts and 240Volt.
8000 watts divided by 240 volts = 33.3 amps
Stove would require 40 amp breaker and 8 gauge wire.

9) How to figure it out:

10) Do same calculation for new furnace.
12000 watt furnace divided by 240 volts = 50 amps.
Use 60 amp breaker and 6 gauge wire.

11) Summary: fixya wants you to be safe, and buy stuff showing in the ads.
Use a bigger breaker ONLY when bigger wire is also installed.
Call furnace installer, the installer should know to check safe wiring before installing.

Hi i have a really old Kawasaki ke 100cc that i fixed up. but is is too damaged to have the lights and indicators. i want to know how to wire the bike up with just the (magneto) cords from the engine to...

no headlight and no start. the starter switch is bad. the switched needs to be removed and cleaned and also the guides for the shunt need to be fixed. the overheating of the switch melts the plastic guides and prevents the shunt from sliding up and down. it sticks in the down position and stops the headlight ans starter from working. when you get the switch working again you should put your headlight on a relay to remove the power draw through the switch.

I have an electric stove that has 1 black, 1 red

Since 1996, the NEC has required that all stoves and dryers be wired with a 4 wire configuration; 2 hot wires (red/black - supplies 240 volts), the bare green ground wire and a white neutral wire. Before you do anything, review this article which speaks to the 3-wire/4-wire arrangement. Good luck!

I live in a mobile home with a westinghouse DP 200 amp main breaker. it trips alot when i run the stove and the dryer along with other items.

You need to run a new circuit to the stove before your electrical wires catch on fire. that is a hazard you have taking a big chance if left alone. Your old wires and breaker is not heavy enough to run both so a complete rewiring job will be in order if not reaired very soon I would say from past experiences I've encountered

Need wiring info for cutler hammer C25DND330 30amp fire shunt breaker...need to shunt 4/220's and 1/110 can you help

Probably easier and about the same price to just buy a shunt trip main breaker. IIRC, code usually requires that anyway.

As far as the c25dnd330, it's just a regular 3 pole contactor, each pole is good for 30 amps. The three poles are L1,2,&3>>>T1,2,&3. The other two contacts are the control coil. I believe your model is 120 volt (most are)....the voltage should be stamped somewhere near the contacts.
