Installation Guide

When it comes to surge protection, no other manufacturer delivers all of the Transient
Voltage Surge Suppressor (TVSS) receptacle options that Cooper Wiring Devices can. Our
TVSS duplex receptacles offer a variety of features to choose from: grounded, isolated
ground, LED indicators and switched alarms. These receptacles provide extra protection
from momentary spikes and surges at point-of-use inside a building.
Most of the new equipment being manufactured today has built-in
microprocessor chips which are extremely vulnerable to momentary surges or
spik
es that occur on an hourly basis.
T
ransient voltage spikes are involved
with an estimated 89% of all power disturbances.
Lighting and utility
switching equipment, air conditioners, pumps, microwaves, copy machines and
po
wer tools are just a few of the devices that can cause voltage spikes.
The effect that these spik
es have on electrical equipment causes varying degrees of damage:
n Destructive is caused by transient spikes that are instantaneous, causing
catastrophic failure (lightning or short circuit).
n Dissipative is the result of cumulative transient spikes that continue to erode the
performance of equipment until it ultimately fails (fax machine ceases to function
suddenly without damage symptoms).
n Disruptive occurs when electronic components attempt to process transient spikes
as a valid logic command, resulting in system lock-up, malfunctions and lost or
corrupted files (computer freezes up).
Ev
en though a building ma
y be protected b
y an outside TVSS panel, additional protection
is needed at the point-of-use on devices inside the building. While a TVSS at the service
entrance protects the building from surg
es entering the building from the outside, it
does not protect equipment from surg
es that occur within a building.
An estimated
63% of transient voltages spikes originate within buildings, leaving valuable
equipment vulnerable to damage. With the addition of surge protection devices on
the branch circuit, equipment is protected from damaging spikes and surges originating
inside the building.
