Q-Line 15 Amp 1 in. Single-Pole Circuit Breaker

There is no standard life span. They can be bad out of the box, fail within a day or last the lifetime of the panel which could be 50 or more years..

Hello. It may fit however you should check the panel. It usually will state what breakers are compatible with the panel. Also, if you have a home Inspection, a decent inspector will check the compatibility. Hope this helps!

General use 120 volt circuits are limited to a maximum of 20 amps by the NEC. Not only would increasing to a 25 or 30 amp breaker be a code violation, but it would also be a fire hazard.

It worked in the electrical panel I had to feed an RV from. You need to make sure this breaker will fit in the panel you have.

Yes you could easily fit 2 12awg conductors on this breaker. No you shouldn't, buy a tandem breaker and place one conductor under each screw. This allows better independent control of those 2 circuits, avoids a splice inside the panel and would not fail in an inspection senario. Check first if your panel accepts tandem breakers.

Unless your new fridge is a Sub-Zero brand fridge, a 15 amp circuit breaker will be enough for even the largest refrigerator you can buy without special ordering.

This is such a basic question I would suggest you enlist qualified assistance to remove your breaker. I would further suggest you ask questions and receive some basic instruction for future use.

They are not the same breaker, but the THQL will sometimes replace the TQL breaker in some applications. Consult the label inside the panel door for breakers that can be used in your panel.

The number you provided is of no use to identify the breaker. Most likely you need a THQL breaker, but I would recommend either taking a picture of a current breaker or taking one into the store to be matched with a THQL breaker.

I believe series II panels use TEY,TEYH,TEYL breakers. You did not specify model but to my knowledge those are bolt on breakers. The GE Q line is mostly for residential stab lock panels.
