At night, I turn off the disconnect, main breaker and all breakers in the electric panel. In the morning, I turn breakers I will be using that morning on. However, shut off valve and manifold to pressure tank underneath my home have frozen and cracked in prior years. To be able to keep the electricity off inside of my home, I had a 15 amp GE breaker installed in the service entrance. This breaker will operate heat tapes underneath my home.
