When a home circuit breaker opens the lights in some rooms go off but the lights in some rooms stay on. Explain why.?

The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.

The exterior garage lights have always been on All garage switches work but none turn these off How do you find the off switch?

Find out what circuit the lights are on by shutting off breakers until the lights go out. Find the wire that connects to that breaker. If there is no wallboard or insulation in the garage , follow the circuit to the light. If there is a switch then it will have to be somewhere in that circuit and before the light fixture. If your situation is different from this, please use the discussion page and explain.

They don't cost that much, and it also depends on where you are. I suggest you approach your electrician or electrical supplier, explain to him what you need it for and then he will then tell you the cost. Installation will be extra, as you can guess.
