Bought wrong panel

turn it to off position and then back, if it still wont reset it has gone bad and needs replacing

Call cutler hammer for nearest distributor. It may need to be ordered.

You can check home Depot for the breaker, they're compatible with Cutler hammer.

It sounds like a bad neutral wire. Somewhere the neutral is not properly connected. Most residential wiring operates on a 240 single phase system comprised of two seperate 120 volt legs. Connect between either leg to the neutral gives you 120 volts.connect btween the two legs gives you 240 volts. If the neutral is not present the circuit will search out the other leg to try to complete the circuit causing dimming of lights extremely bright lights and all around chaos. Check ahead of the main to see that the voltage is correct. Check each leg to neutral with a voltage tester. Have some one turn some lights on and off while checking as sometimes a load is required to get fluctuating readings. If the reading fluctuate wildly the problem is between the power grid and the panel. If not recheck on a a couple of breakers and if the readings fluctuate it is on your side of the system.

It sounds like you have a main lug only panel. They are for sub panels where a main breaker isn't needed. I would return it and get the right one.

To do this safely you should call an electrician. No way I can give you complete instructions that will be sure to be safe because I can't see exactly what the situation is that you have. But the basic steps include: turning off the main, understanding that you are about to expose the feed lugs TO the main which are still LIVE (and giving them a wide berth!), carefully removing the cover, CONFIRMING that everything else in the box is NOT LIVE (use a non-contact voltage detector - $15 or less), removing the wire from the old breaker, pulling the old breaker out, plugging the new breaker in, connecting the wire to the new breaker (nice and tight), replacing the cover and then turning the main back on.

Hi .. If the load center is next to the main panel you can use #2 copper or #1aught aluminum. You need to use 4 wires .. two hot, neutral, and ground. And in your load center you will need a 125amp main breaker and you will need to keep the neutral bus separate from the box, do not use the bonding screw. You will then need to install a ground bar to the back of the box for the ground wires connection.
any thoughts, questions.?

Please call an electrician. There are 3 possibilities---- 1. The sum of the branches are occasionally spiking higher than 200 amps. (If you add up all of the branch ratings you will find that their combined capacity is much higher than 200 Amps in total) In this case you need to find a way to level the load or add capacity by adding a second breaker box -- you can't do this yourself because you need help from the utility company. 2. There is something shorting out inside your breaker box. (unlikely) 3. There is a problem with the main and you need to replace it. But DO NOT ATTEMPT TO DO THIS YOURSELF. In all three cases you need help from an electrician.

I was able to go online and locate numerous sites that offered the ability to order the CH2100 and also the CH2100x main breakers. You could also take the breaker to an electrical supply and see what they have to offer as a replacement, but be sure that the connectors in the panel are not damaged before purchasing and installing a new breaker.

no this is not normal sounds like it has gotten hot a couple times but they are easy and cheap to replace shut off your main breaker at the top of your panel then take the cover off most breaker just snap in you might have to slide it under one side then press till it snaps in onthe other side but some cutler hammer and others have a screw in you hook it in on the back of new breaker and put the screw in the front any way if you need more help i can find a diagram on your brand of breaker and tell you exactly how to do it
