    How to quickly disconnect power from a primary distribution box

    To turn off power supply, firmly switch the main circuit breaker or main service disconnect to the Off position. So, to add confidence to your maintenance or repair activity, it's better to cut off the primary power source before your breaker panel. Turning off the main electrical source before the breaker panel usually doesn't require. Always shut off the power to an outlet before working on it—and then test with an electrical tester to be sure there's no voltage present. This breaker acts as the designated disconnect switch. To shut off the electrical power to your entire house, locate the main electrical panel (it pays to know where this is before you need it!) and flip the main circuit breakers at the top (usually a pair) to OFF.
