What’s That Green Wire For?

One of the most common problems we find with electrical installations, whether it be a do it yourself renovation, or even new construction, is finding that the ground connection is not properly terminated to light fixtures, switches and outlets.  They will work without making that connection, but for devices that include a ground connection, it is very dangerous to leave it disconnected.

What does the ground connection look like?  It’s the green screw on light switches and receptacles, and it is usually a green or bare wire on light fixtures and ceiling fans.

Why is it important?  The ground wire is used to make sure that the metal surfaces a person could come in contact with in an electrical system do not become energized, creating a shock hazard.  When properly connected, the ground wire creates a “short circuit” pathway for electrical current to flow in a large enough volume to trip the circuit breaker off in the event that the “hot” wire comes in contact with any metal it is not suppose to.  Without this ground pathway, current can’t flow, and the breaker can’t trip.   The metal would then become energized, waiting for someone to touch it.  When a person touches the energized metal they become the pathway for current to flow, leading to injury and sometimes death.

How to Troubleshoot a GFCI Receptacle

GFCI stands for Ground Fault Circuit Interrupter.  The GFCI is a device designed to provide protection to users from electric shock.  This special receptacle works by constantly monitoring the flow of electricity in a circuit.  If a loss is detected, the GFCI will trip and stop the flow of electricity to the circuit preventing injury from electrocution. It is much more sensitive and will respond much swifter to a problem than a fuse or circuit breaker.  Since their introduction in 1971, it is estimated that GFCI’s have reduced the occurrence of electrocution in homes by over two-thirds.

10 Electrical Safety Tips for the Holiday Season

As the holidays approach, many of us will be using lights and other electrical devices to decorate our homes.  As we do this, we need to be mindful of the dangers that are always present when electricity is being used.

According to the U.S. Consumer Product Safety Commission (CPSC), each year hospital emergency rooms treat about 12,000 people for injuries related to holiday lights, decorations, and Christmas trees.  In addition, dried out Christmas trees are involved in hundreds of fires annually. Read more
