Light Pole Hand Hole
The Edco SHAS Series surge protector is a compact device that is designed to be
installed directly within a light pole to protect the sensitive lighting ballast or
power supply from damaging transients. The Edco SHAS Series easily fits into the
3” x 5” hand hole located at base of the light pole and is wired in series with the
load for the best performance. This series contains a green status LED that will go
out in the event the units protection has been reduced. This enables maintenance
personnel to identify if the unit needs to be replaced.
Electronic high frequency ballasts are more susceptible to line
transients than line frequency magnetic ballasts. Therefore,
transient protection shall be included...IEEE C82.11-2002
Surges are an everyday occurrence and can come from a host of different sources. We typically think of a lightning
strike as the major culprit of equipment damage and though lightning CAN cause catastrophic damage in a single
incident, over time, it’s actually lower level transients that wreak havoc with sensitive electronic components,
including ballasts and switch mode power supplies, (in LED lighting).
The breakdown of these electrical components may cause intermittent light distribution. If these malfunctions are not
repaired in a timely fashion, parts can overheat, wires can melt, causing a fire or the fixture could explode, showering
glass and debris to the ground, not only resulting in a replacement cost of the light itself, but an expensive service call,
as a response would require a qualified electrician and an arial bucket truck.
Additional sources of transients to consider are those generated from utility grid switching, individual pieces of
equipment (or loads), and traffic accidents. All of these sources are potentially damaging to unprotected equipment.
This could mean street and parking lot lights, but it also includes the main source of power, the main electrical service
supplying the equipment.
In addition to being a ‘best practice’, including a surge protection device into the base of the light pole fixture
is relatively inexpensive and easy to install. Surge protection is the problem solving solution in reducing overall
maintenance costs and improving safety.
