What happens in this clip
Before proceeding with any electrical work, locate the main electrical panel (usually in a basement or utility room) and identify the circuit breaker that controls the light fixture. Turn this breaker to the 'OFF' position. Double-check that the power is indeed off at the light fixture itself by attempting to turn it on via the wall switches, which should now be unresponsive. This is a critical safety step to prevent electrical shock.
Goal: Ensure no power reaches the light fixture to be worked on.
