Common residential electrical problems include defective bulbs and switches, dead outlets and the tripping of circuit breakers. Other problems may involve power surges, outlet sparks, power outages and sags.
Light bulb problems include flickering lights and bulbs burning out at a higher rate. Flickering lights may be caused by a poor connection on the circuit that could lead to broken connections. It can also arise from a faulty main wire connection in the system. When a bulb burns at a high rate, this signifies the use of a low quality bulb.
Failure to reset breakers and poor connections along the circuit can lead to dead outlets. When some portions of the outlet don't work, this indicates the over-use of the connection cords. Electrical outlet problems may also arise when breakers are tripped or the outlets burn out, indicated by the blackening of the outlet plugs. Use of high wattage electrical equipment may lead to overloads along the connection, causing the breaker to trip.
Power surges and spikes stem from sudden bursts of additional voltage arising from external events such as storms and accidents. The sudden increased voltage can destroy electrical equipment and home appliances. On the other hand, brief low voltage periods lead to power outages, sags and dips. Power outages may result in blackouts resulting from weather conditions, damage to power equipment and electrical short circuits.
