Warning Signs of Electrical dangers

There are several ways you can assess your risk and make simple changes to reduce the hazards that may be present in an electrical system. By ensuring that your home undergoes a thorough electrical inspection completed by a qualified electrician before buying, selling, or remodeling a home, you can help make certain your home’s electrical system operates at the highest level of safety possible.

circuit breakers

Warning sign: Frequent or re-occurring issues with blowing fuses or tripping circuit breakers
If a fuse opens or circuit breaker is tripped, be sure to investigate the cause before replacing the fuse or resetting the breaker. If necessary, call a qualified electrician to investigate the cause.


Warning sign: A tingling sensation when you touch an electrical appliance or other metal objects
Getting a shock when you touch appliances in your house can indicate a more serious problem. Be sure to unplug the appliance and discontinue use.

discolored outlet

Warning sign: Discolored or warm wall outlets, or Sparks from an outlet
This can indicate arcing, smoldering, burning happening behind your outlets, damaged or improperly installed wiring in the outlet, or a problem with the receptacle itself. Avoid using the outlet or switch and contact a qualified electrician as soon as possible.

old appliances

Warning sign: A persistent burning smell coming from an appliance, room, or area
This can indicate that the appliance is overheating or malfunctioning. Unplug the appliance or turn off the circuit breaker.

dimming lights
