CP could be Control Panel? for an alarm system.

Or you may have the main breaker for the Canadian Pacific railroad.
Turn it off and see if trains stop.

TC could be trash compactor. Do you have one?

On a rainy Saturday when you have nothing to do, check out what braker
does what if the labels look at all confusing.

Good advice, and mine are pretty well labeled by the original
electrician, I think, but in all these years, only one or two have ever
tripped, plus one or two I turned off to work on the circuit. I don't
really know what the others do.
