NSS Linegard GFCI Installation And Testing Procedure

INSTALLATION AND TESTING
PROCEDURE
IMPORTANT!
THIS DEVICE MUST BE INSTALLED BY A QUALIFIED
PERSON WHO UNDERSTANDS ELECTRICAL
CIRCUITS.
Please read all the information on this sheet.
WARNING
A Ground Fault Circuit Interrupter (GFCI) is an electrical
safety device that under normal use is intended to mitigate
electric shock hazard. Use this product only within the
specified operating parameters. (Failure to do so may result
in bodily injury.) Consult a licensed electrician for assistance
on installation and repairs. Do not use this GFCI if it fails to
function as instructed. Never attempt to tamper with this
device. This GFCI must never be used as a switch to
connect or disconnect power.
disconnected at main power feed or by secondary switch
located at the primary feed of GFCI.) This GFCI is not an
over-current protection device. (An appropriate fuse or
circuit breaker must be used in series at primary power
feed.) This GFCI does not provide protection against shocks
caused by holding both circuit conductors. This GFCI does
not provide protection against electrical shocks generated
by the conductors supplying power to the device. Note:
primary feed to GFCI is live even when GFCI is tripped.
(Power should be disconnected at main service panel
before servicing load side of GFCI.)
 Do not use this device to feed power to life support
apparatus.
 To minimize nuisance tripping:

Do not use on swimming pool equipment
installed before 1965 NEC code.

Do not use on electric clothes dryers or electric
ranges with frames grounded by neutral
conductor.
 Installation must comply with local and national
electrical codes (NEC).
 During installation, turn power off at the service panel to
prevent serious injuries.
North Shore Safety TWO YEAR LIMITED MANUFACTURER'S WARRANTY
North Shore Safety warrants to the consumer its Line-Gard Ground Fault Circuit Interrupter (GFCI) to be free from defects in
materials and workmanship, under normal use and service, for a period of two years from date of purchase. North Shore
Safety, at its option, will repair or replace the defective GFCI without charge within 2-years of the date of the product's
purchase provided that the defect occurred during normal use. The defective unit must be returned freight prepaid, with a RGA
(Returned Goods Authorization) including a description of the problem, and a proof of purchase date to the Quality Assurance
Dept. North Shore Safety, Ltd. 7335 Production Drive, Mentor, OH 44060.
North Shore Safety will not be liable, directly or indirectly, for installation or removal of this device, or for any personal injury, or
property damages, or incidental, indirect, or consequential damages of any kind, as a result of a defective device. The
exclusive remedy, under this warranty, is the repair or replacement of the defective device. In no case shall North Shore
Safety's liability exceed the purchase price. This warranty is void or not covered if this device is found to be: not properly
installed, tampered with, not used according to label instructions and ratings, enclosure breached (button cover label, conduit
hubs, vent, or lid fasteners), surged, short circuited, or abused.
(Power should be
What is a GFCI?
A GFCI is a device designed to interrupt power when a
ground fault (a current that takes a path to ground) exceeds
a predetermined value. This power interruption is quickly
accomplished to prevent serious injuries.
Why do we need a GFCI?
The human body is conductive to electricity, and electric
shocks can be fatal. Any electrical tool or appliance is a
potential shock hazard, especially when used near wet
locations; and this is where a GFCI is needed the most.
This is why most electrical codes require GFCI protection in
kitchens, bathrooms, garages, outdoor outlets, laundry
rooms, workshops, etc.
North Shore Safety's GFCI, LineGard
protection. Its safety scope surpasses its peers to include
open supply protection (most receptacle type GFCIs do not
sense open neutral condition) as well as dual indication of
operating modes, with fault indication or power status.
How does a GFCI operate?
The GFCI constantly monitors the current-balance of the
conductors supplying power to the load. When a ground
fault occurs - by a leakage or by shock - the imbalance of
current is sensed and the GFCI trips when the ground fault
exceeds 5 mA +/- 1 mA. The tripping action must be within
a fraction of a second to prevent serious injuries.
What a GFCI cannot do:
 Will not protect the circuit's line side.
 Will not protect you when touching two current carrying
conductors of opposite polarity (the GFCI sees this as a
load).
 Will not protect you when touching a line of another
circuit.
 Will not detect over-current.
