Whole home/office surge suppression systems

Thursday, June 19th, 2014

Spikes in electricity can destroy electronic equipment in your home or office. These surges, many times caused by lightning storms, can destroy your computers, office equipment, heating & cooling systems. televisions, dishwashers, washing machines, dryers, stereos, gaming and home theater equipment beyond repair. Virtually anything that contains electronic components and that you have connected to your building wiring is in danger. Small power strip surge protectors are not your best choice. Whole house surge suppressors installed by a licensed professional electrician can save you from costly replacements or repairs.

What is whole home/office surge suppression? Surge suppression equipment keeps all of your electrical devices safe from sudden surges and spikes in the electrical power supplied to your home or business. Power surges can damage any type of electrical equipment, particularly if it contains electronic components. What has become known as a whole home or office surge suppression system, this type of protection is generally attached at the main service panel usually located adjacent to the electric meter. These devices are intended to stop voltage surges from entering a buildings wiring via the conductors extending from the service equipment, thereby protecting all of your equipment attached to your electric service.

While surge protector strips can protect just a few 120 volt electronic devices (computers, monitors, TV’s, etc.), a surge suppressor installed at your service panel can diffuse a power surge from ever entering the building and will provide protection for 120 volt as well as your 240 volt equipment. Many home and office owners have a false assumption that surge protection is simply a matter of plugging their devices into a low-cost, multi-outlet surge suppressor. These devices often fail, while a surge suppressor is much more reliable and provides greater protection.

What Are Ground Fault Circuit Interrupters? Answers from Duffy Electric

Ground Fault Circuit Interrupters…what you should know from Duffy Electric in Tucson, Arizona

GFCI functions by electronically sensing current flow differential between two current carrying conductors (hot/neutral).  Should a difference of five milliamps be detected (5/1000 of an ampere, .6 watts) the device will be tripped out.  It de-energizes itself and all receptacles being protected by it downstream.  This serves to provide personal protection from electrical shock.  This is its proper function.

Rather than blame the GFCI, look for a problem with connected loads.

1.) Unplug all appliances, lights, cords, tools, etc.

2.) Reset the tripped GFCI receptacle.

3.)Plug-in all items disconnected in #1 , one at a time.  Operate the device.  If no tripping occurs, plug in another item.  Follow the same procedure one item at a time.  When the GFCI trips, the last item plugged in is the source of the problem.

4.) Leave the item unplugged until it is repaired or replaced with a properly functioning item.  Reset your GFCI.
