Service Panel and Breaker Compatibility
Hi all. This is my first post here--what a great site!!.
I'm fairly new to working with electricity and with home wiring, and want to make sure that my first foray inside the service panel is a safe and productive one.
So, how does one ensure that a given circuit breaker is compatible with a given service panel?
My panel has the logo with the capital letter D inside a box. The main label on the panel contains this information:
CAT. QO-40M SER. T4
200 AMP CU/AL
3 other stickers inside the panel give the following information:
Made in U.S.A.
40 degrees C
Tighten to 250 lb. in.
Serrer a 250 lb. po.
#4 - 300 MCM CU/AL
120/240 V. AC
SQUARE D. CO.
The circuit breaker itself also has the logo of the capital D inside a square and, in various places:
UL listed C.B.
That's all I can find--I've heard that an incompatible panel and breaker are fire hazards so I definitely wanted to check this out first. Thanks in advance for any help!
