Homeowners can take a few safe steps to keep track of electrical equipment, but fixed wiring and panel work should be left to qualified professionals.
Look for visibly damaged power cords and stop using damaged items.
Keep electrical devices and extension leads away from water.
Avoid daisy-chaining power strips or overloading outlets.
Keep the area around the electrical panel clear and accessible.
Make a note of recurring issues such as flickering lights or tripping breakers.
Call a qualified electrician for recurring breaker trips, warm outlets, buzzing, burning smells, damaged fixed wiring, or any work involving panels and circuits. If there is smoke or fire, evacuate and call emergency services.
