Siemens 80 amp breaker replacement
Hi,
I have a 225 amp Siemens panel model g4242mb1225 which I need to replace a breaker on.
Its an 80 amp which goes to a sub breaker box for the upstairs wiring.
All the lights on that sub are flickering and the breaker is buzzing.
I need it as soon as possible, but HD and Lowes don't seem to carry it in store.
Is there an equivalent I could use? Would be work instead or any other brand?
Thanks
James

Have you pulled the breaker and checked the condition of the buss bars then reseated the breaker?

Its a 2 pole. I dont know much about electrical - I had an electrician round to replace the main 200amp breaker which was hot and burning, and he replaced it with a 225.
He said he also noticed the 80amp breaker to the (125amp) sub panel also needed replacing but he didnt have one to hand and told me I could do that one myself.
He actually recommended upping the amps to 90 or 100. ?!?!
It powers the sub which powers all the upstairs, my downstairs lighting and my living room. So it does have a lot to do.
Lowes has the siemens 90amp in stock, so I need to be sure that this is not too high.
Its obviously below the 125 rating for the sub panel, but does this mean the wiring inbetween the main panel and sub panel will take more amps? (not that I'm ever likely to draw 90 amps from these circuits)

Unless you can determine the size of the wire, wire material, and wiring method, I would just replace it with one with the same rating. 80 amps is not as common as 100 amp breakers sio it is likely an 80 for a reason. If you never had an issue with it tripping there really is no advantage to up the size IMO.

Unless the wires are rated for more than 200 amps the breaker change has created a fire hazard.
