If you are not familiar with electrical wiring, I would suggest an electrician. NEVER TRUST COLORS! Most of the time, white goes with white, black with black, red with red, and bare to bare. But depending upon whether this is a 110 or 220 they could be mixed up depending upon how the feed wire is wired at the box. Hope this helps! c

If the breaker is not a ground fault breaker, then you you have an over current situation which could be caused by the pump in the well or the wiring in between.
You said it burnt the wires which tell me that one of two things happened. 1 the pump had a short internally which gradually caused the current to increase which would not of blown the breaker. 2 the breaker was defective and allowed the pump to draw excessive current and burn the wires supplying it's power.
As mentioned above you have a bad pump or shorted wiring.

Wire wont fit in new coleman breakers


Hi - I'm an electrican and would like to help.

If the wire you're trying to install on a circuit breaker doesn't fit - then something is wrong. Typically, circuits are designed around the amount of voltage and current a product requires. The voltage determines the combination of material & thickness of the insulation on the wire and the the amount of current (in amps) determines the size of the conductor or wire. The appropriate circuit protection (fuse or circuit breaker) is selected to protect the circuit from trying to deliver more current than the product requires (in the case of a fault, etc.) which would cause the wire to over heat and potentially cause a fire. So, if the product requires (for simplicity) 120 volts and 20 amps, a wire is selected with the proper insulation for 120 volts or more and conductor sized to carry no less than 20 amps. Aluminum and copper is expensive, so providing larger sizes than needed is a waste of resources and money. A #12 copper wire is suitable for this amount of amps. A circuit breaker rated for 20 amps is chosen. A 20 amp circuit breaker must be able to accept a wire capable of 20 amps - other wise it's not really a 20 amp circuit breaker. Most circuit breakers are designed to accept LARGER wires than needed - because often times circuits will need a wire that is one or two sizes larger due to the length of the circuit (how far the product is from the electrical panel).

If you're seeing a circuit breaker that will not accept the wire, the circuit breaker is probably the wrong size (and if you could force the wire in it - it would probably trip instantly when turned on) or someone has made a very expensive blunder when chosing the wire type and size for the circuit.

If the the latter is the case, simply connect a short length of the correct size wire to the oversized wire in an appropriate connector and secure to the circuit breaker terminal screw. otherwise, have a qualified person evaluate the situation. Be smart. Be safe.

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:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-install-a-subpanel.html

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.

Can a tandem breaker fail in a way that the two circuits are tied together somehow within the breaker?


Charlie,
If these tandem breakers are the separate 1/2 height breakers in the space of a normal breaker, then no, they can't fail internally to cause what you are describing. But if you have the kind that are permanently stuck together, then I can't say. But here is a simple test: Use a meter or a test light to confirm at the breaker terminals that turning off either one of the breakers still gives you power at both breaker output terminals. Now turn off BOTH breakers, and disconnect one output wire (being careful that the loose wire isn't going to touch somehting!), then turn on the breaker that still has an output wire connected - if the loose wire is live then you have a wiring error where both circuits are connected together downstream. If that is the case, then it may have been intentional as a way to "fix" a frequently tripping breaker by giving it a second chance each time it tripped! (This is a pretty far-fetched idea, but it may give you something to think about!) If it was me, I would just replace the tandem pair with a single breaker and put both of the output wires together on the single breaker.
Good luck! Be careful.

Have Challenger Type C 2100 circuit breaker in residential home electrical panel. Manually turned to off position and now cannot turn back on. Pops back to off position. Also says HACR type and common trip...


First HACR is heating, air conditioning,refrigeration. So in other words you could use it on an electric furnace or air conditioning.
IS this the main breaker for the panel? or for and electric furnace. I'm assuming its for the furnace, perhaps back up heat for heat pump. See if there is another disconenct on the furnace, turn it off and see if the breaker resets. IF so you have a short or overload in the furnace.
If' it IS the main for the panel, turn off all the other breakers in the panel, and try to reset the breaker. If that works, turn the other breakers back on one at a time. IF it "POPS" then it is tripping. Don't keep resetting, find the problem.

Electric furnace wire heating up


you should have a 3- conductor # 6-3 copper wire running to this 60 amp breaker @ the furnace to the panel if this is not the case you should replace this with a # 6 as of now as it is a fire hazard as it is and needs to be fixed at once , # 10 -2 wire is only good for 30 amps and a 60 amp breaker will not trip under fault condition and you could have a fire , if you need further assistance on this let me know and i will try to help
