Electrical Problem: Conservative Field Checks

Confirm the scope of what is dead, test the GFCI and breaker once, and unplug suspect loads. If a breaker trips again, if you smell burning, or if any panel or device needs to be opened, stop and call a licensed electrician. Do not take live readings unless that is your qualified, authorized work.
