Electrical safety No. 1 priority

Flickering or dimming lights could indicate overloaded system

Electricity is such a fundamental part of our everyday lives that we hardly ever think about how it works or any safety issues that could occur as a result of our plugged-in homes.

Here are five electrical safety facts that you should know to protect your family and your home.

Flickering lights

 If lights flicker or dim repeatedly, you should call an electrician.

Flickering or dimming lights signify an overload, and a professional should be contacted. 

Power outages due to power line accidents, strong winds, storms or extreme heat also can cause brief interruptions. 

You can call your power company to find out details on the situation or check your circuit boxes for those outages. 

You also should call your electrician if you are constantly resetting circuit breakers or changing fuses, smell the scent of something burning or need to replace faulty wiring.

Losing power

Your house may temporarily lose power due to weather issues or even on hot summer days when there’s high demand for air conditioning. 

If you experience an outage, turn off all of the appliances in your house to prevent a circuit overload or even another outage when the power is restored.

Electric companies recommend leaving one lamp on so that you'll know when the power is back.

House wiring

Depending on the amount of use, insulation on house wires can become frayed or broken, creating a fire hazard. 

If you have any doubts aboutyour wiring, have a qualified electrician perform a complete inspection. 

Houses built between 1965 and 1973, in particular, are at risk because many were built with aluminum wiring. That type of wiring the U.S. Consumer Product Safety Commission says is 55 times more likely to reach “fire hazard conditions” than regular copper wire.

Circuit breakers

A circuit breaker is not designed to protect against a ground fault.

Circuit breakers are designed to protect against high levels of electrical current caused by a short circuit. 

Ground Fault Circuit Interrupters (GFCIs) protect against ground faults, when current leaking from an appliance goes to ground through a persontouching the appliance. 

Even a small amount of current passing through a person this way can be lethal; a GFCI will trip if there’s a ground fault; a circuit breaker won’t.

Using power tools

You can damage a power tool by using the wrong size extension cord.

If your electric lawn mower, hedge trimmer or leaf blower doesn’t get enough power, either because the extension cord is too thin or too long, the motor can be damaged and eventually destroyed. 

Also, overloading an extension cord can cause a fire or shock hazard. 

Be sure to use a cord rated to provide the proper amperage the tool requires. That information can be found on the tool.

Just a little electrical knowledge can go a long way. 

Remember, when dealing with electrical issues in your home, safety should be your number one priority.
