No. your panel is designed for full size circuit breakers. Check the label inside the panel and it will tell you what style circuit breakers are allowed.

yes it will, you need to always make sure that you put the same brand in the panel box, good luck

Usually siemens, murray, cutler hammer will interchange

You will solve the problem of the breaker tripping but you'll create a fire hazard as the wiring may overheat because of what you are drawing through the line. If you need a higher amp circuit breaker for the load you are creating on the line, you need to make sure the wiring can also handle the extra load. You'd be way better off by spreading the load over several different circuits or installing another line to reduce the load on the line that's tripping the breaker.

Hi. I'm a Siemens employee directly involved in helping customers with this situation. You may check the following website for information on the breakers affected. Please use the response form there if you need further assistance:

Also, you may check with your local distributors for assistance with replacements. They have quarantined the affected breakers and should be able to sell existing unaffected stock.

Enter your zip code and choose Residential Products or Murray depending on the branding of your circuit breaker.

i will double check my supplier to see if they actually stopped making them but even if they did almost all breakers will interchange with other brands like a siemens and a ge will interchange etc. any electrical supply store should be able to cross reference your model number to one that will work

sounds like a loose connection ,or possibly a weak main breaker.

faulty, exchange it
