Common residential problems include defective switches and bulbs, tripping circuit breakers, loose wiring, dead outlets and circuit overloads. Other problems may involve outlet sparks, power surges, redundant wiring, power sags and outages.
Light bulb defects include bulbs burning out at a higher rate, flickering lights and recessed lights. Flickering may result from a poor connection in the circuit. This could lead to broken connections, causing the constant blinking of the lights. It can also be caused by a faulty main wire connection in the circuit system. When the light bulb burns at a higher rate, it signifies the use of poor quality bulbs.
Dead outlets are caused by poor connections along the circuit or failure to reset breakers. Overuse of the power connection cords causes failure of some portions to work. Strain on the circuit connection by using multiple electrical appliances may cause circuit overloads. Electrical outlet problems are caused by tripped breakers or burnt outlets. Wear and tear of wires and damaged power cables can cause loose wiring.
Power spikes and surges are caused by sudden bursts of excess voltage arising from accidents and storms. They can destroy home appliances and electrical equipments. Clustering of improperly uncapped and terminated wires causes redundant wiring. Power outages, dips and sags are caused by brief low voltage periods along the connection.
