Delmarva Power Recommends Surge Protection for Home Electronic Equipment

Monday, April 12, 2010

NEWARK , Del. – When it comes to expensive home electronic equipment, Delmarva Power reminds customers to take the necessary steps to protect it from power surges.

A power surge is an increase in voltage significantly above the designated level in a flow of electricity. In normal household and office wiring, the standard voltage is 120 volts . If the voltage rises above 120 volts, there is a problem that could result in the loss of electronic equipment.

“A voltage surge is the most serious form of power interference, which can occur inside or outside a home, and can damage sensitive electronic equipment such as computers, printers, treadmills, and other electronic devices,” said Glenn Moore, Regional Vice President, Delmarva Power.

Delmarva Power encourages customers to invest in one or both of the following types of surge protection:

· Surge Suppressor – This most common surge protection device is a power strip that can handle up to 6,000 volts.

· Surge Arrester – This is installed in or near a home’s main electric service panel and offers protection against voltage surges up to 20,000 volts (such as a lightning strike).

Delmarva Power also warns against confusing a standard power strip with one that offers surge protection.

“Both power strips and poorly made surge protectors can overheat during a surge and set electrical devices on fire,” Moore said. “The surge suppressor and arrester will divert the short-lived electricity into the outlet’s grounding wire,” he added.

“For maximum protection, consumers should invest in suppressors and arresters, ensuring the voltage surge gets reduced enough to prevent the loss of any and all home electronic equipment,” Moore said. Electrical surge suppressors can be purchased at most hardware or home improvement stores; the whole house surge arrester should be installed by a licensed electrician. Please note: neither a surge suppressor nor surge arrester guarantees protection from power surges in all instances.
