Breaker Question


I have a GE panel and they have the thick 20amp breaker and the skinner 20amp breaker? What is the difference and can I take out the thick 20amp breaker and put in 2 of the smaller? They look like the would just fit in.

yes these are mini or tandem breakers. They only fit in certain sections of the panel. Look at the label and you will see where these can fit.

There is a line diagram that shows the breaker slots. Some show one spot with two breakers that can fit there. If this breaker fits, it will be fine. The areas that the breaker is not designed for will have a different center bus and they cannot fit in that slot.

They aren't Tandem. They are the "Half Size" and "Single-pole", which is the thicker one. There is only one place for the wire, unlike the tandem that there is 2.

Actually I looked and there is a tandem (2 of the half sizes) of 40amp each that is one is installed in half of position 15 and the other 40amp breaker is installed in half of position 17. Is that normal? Should they be installed in the same slot? This is for 2 wires going to the Air Conditioner.

That's called a double-pole breaker. THQP type.

While those half-pint breakers may "fit" into any slot in your panel, that is by no means a guarantee that there is a bus bar section for them to grab in every section. You end up with what appears to be a dead breaker in some instances.
