A Challenger 20 Amp single pole breaker shouldn't be priced much different than any other brand of breaker if you buy them online and not at Home Depot. That is if it isn't the Zinsco style like these:

According to Eaton's cross reference a BR 120 will cross with a C 120. You can find the cross reference here:
Lowes shows the BR 120 at 3.47

They look like these:

Challenger A1515

It appears that Siemans, Murray, Eaton, and Square D are compatible. Look for those brands with "1515" in the part number, such as MP1515, Q1515, BR1515, HOMT1515. Challenger is presume\ably no longer in business.

Following link shows $97.
20 years ago they sold main breakers for 100$.

Certainly buying a breaker is cheaper than installing entire new panel.

What GFI breaker is compatible with a Challenger Breaker Box

The National Electrical Code prohibits the use of mixing circuit breaker manufacturers and circuit breaker panels by requiring all electrical equipment to be certified (UL Listed, FM, etc.). Challenger breakers are UL listed, as are Challenger panels. All the circuit breakers installed must be made by Challenger and must be approved for use in that particular panel (more on this below). Installing a different brand breaker into the panel causes the panel and the breaker to lose the UL / FM listing. The lack of a listing causes the electrical code violation. Should a fire occur, and the source is determined to be the use of a mixed manufacturer panel / circuit breaker installation, you insurance company may balk at paying a claim.

If you are unsure of the circuit breakers that are approved for use in your panel, look on the inside cover of the door. On it should be listed the manufacturer's name and all the devices that that the panel will accept. Deviating from the list will trigger the loss of listing.

A final thought: Most GFI breakers are much more expensive than a GFCI outlet. Install a standard non-GFI Challenger breaker and feed a new outlet (next to the panel) with a GFCI plug via the LINE terminals. Connect the rest of the old circuit to the outlet's LOAD terminals. The portion of the circuit that is connected to the LOAD terminals are now GFCI protected. Overloads will trip the circuit breaker as usual, but ground fault issues will trip at the outlet instead.

I hope this helps and good luck! Please rate my reply. thanks.

How to change a breaker in a challenger panel

Turn off the main. Carefully remove the cover (held on by 4 corner screws) --- the fat wires coming in to the main will be exposed and they are very much LIVE. Remove the wire on the existing breaker by loosening the screw and pulling out the end of the wire. The end of the breaker that held the wire just pulls out. The other end of the breaker is held under a hook that will easily disengage. Replacement is reverse of removal. BE VERY CAREFUL OF THE WIRES AT THE TOP GOING TO THE MAIN. If you are not sure what the main is, or you don't know what I mean by the wires going into the main, then DO NOT ATTEMPT THIS REPAIR YOURSELF!

What other brand will fit a challenger 100 amp main breaker?

You can only safely use breakers listed for your panel . It will depend on the style of the challenger breaker you are using. Go by the breaker number you currently have and it may cross over to a different brand with same part number . There are two basic Challenger styles. The Zinco/Westinghoue/Challenger Long skinny Like thi one.

I have a residential panel with all Challenger circuit breakers with the exception of a single GE breaker. Challengers say Type C115 and GE says 15A. Can you tell me if these are compatible?

You should only use breakers listed for the panel you have Look on the inside cover of the panel and see what breaker numbers are listed. Many breakers will fit, but are not listed. They are both 15A, but you didn't indicate what brand of panel they are installed in. Most likely, the GE breaker was added,

Main Breaker (QFP-2T) Opens intermittently (about once a year) independent of load or temperature. It doesnt open all the way and have to switch off and then on and it works okay for quite a while.

Usually when old breakers do that they are near being worn out and should be replaced. Unfortunately that breaker is expensive, probably about $200 if you can find one. It's possible that you may have a branch circuit that is (intermittently) faulty and the circuit breaker protecting _that_ circuit is not functioning correctly, thus causing the main to trip (as it should).
It would be safer and cheaper to replace the entire electric panel if you DIY.

Air conditioner trips breaker

The circuit breaker could be tripping because its old and getting too warm; it could trip because of a short circuit or an overcurrent condition. You need an ammeter so that you can check the current draw on the line.

The ammeter will also assist you to find which component is drawing too much current, or if the problem is a short circuit.
