INTRODUCTION
The PG60-80-100 Series is designed to be installed in very close prox-
imity to the power bus of an electric distribution panel or electric panel-
board. It can be used with most panels or panelboards in distribution
today. The PG60-80-100 Series offers peak surge amperage protection
levels of 60 kA to 100 kA per mode. It is designed to be easily mounted
above or below the panelboard. Provisions have been made with a
reversible cover plate to keep the instructions and indicators in a user
friendly position. Standard features include all mode protection, multi-
mode LED indicators that show full protection, diminished protection and
lost protection for all phases. A form C relay for remote alarm indication,
audible trouble alarm with test and silence switch are also standard
equipment.
The system is comprised of three sections; outer housing, cover plate
and inner module. Each section is engineered to make the installer/ser-
vice technician's task as easy as possible. A description of each section
and the function follows.
Outer Housing - Metal housing measuring 20" wide x 16" high x 6"
deep. The outer housing contains the inner housing. connection lugs for
each phase, neutral and ground, connections for the form C alarm relay
and the audible alarm test and silence switch.
A 5/8" flange on the forward side of the housing has ten (10) threaded
holes that are used to attached the cover plate. Four (4) mounting holes
are located in the back surface of the housing for mounting. It is sug-
gested that all four (4) fasteners be used to secure the outer housing.
Cover Plate - Metal plate measuring 19 13/16" wide x 15 13/16" high.
The cover plate contains ten (10) holes located around the edges that
matched the threaded holes in the outer housing and are used to secure
the cover plate to the outer housing. The cover plate is reversible and
has an identification label on both front and reverse sides. The labels
are mirror images of each other and selection of which side to use
depends upon the placement of the outer housing. (This process will be
explained in the installation section that follows.)
Inner Module - Metal box measuring 13 3/16" wide x 9 3/4" high x 4
15/16" deep including the mounting rails that are part of the module.
The inner module is fastened to the outer housing with four (4) bolts
through the mounting rails. Module identification and wiring diagram
labels are attached to the inner module. The inner module contains all
of the surge suppression, noise filtering, fusing, monitoring and reporting
components. Copper bus bars and terminal lugs extend from the inner
module.
NEC Section 285 requires that a SPD have a fault current rating equal
to or greater than the point of installation (switchboard or panelboard).
The PG60-80-100 Series is suitable for use on a circuit capable of deliv-
ering not more than 200,000 amperes (120/208-3Y, 120/240-2S,
120/240-3HLD, 277/480-3Y models). 480-3D models are rated at
25,000 amperes. Should you require a 480-3D model with a higher fault
current rating consider Intermatic PG2500/PG3000/PG3500 Series
which are rated at 200 kAIC.

the SPD to the appropriate points on the electric panel. See
T able 2 for recommended wire and breaker sizes.
Use of a ded-
icated circuit breaker is optional since the SPD has integral
overcurrent fusing.
The SPD can be connected through feed-
thru lugs on a panelboard. The SPD can be connected through
a breaker or direct tapped for Switchboard installations.Select a
position for the connection that results in the shortest lead
lengths between the SPD and the power bus. Leads should be
kept as short as possible to insure optimum operation. Measure
and cut all leads to proper length. Strip the ends of each lead
9/16" for the SPD terminal lugs and to proper length for the
breaker used. Connect the wire leads to the lugs on the bus
bars of the SPD. T
orque the lugs 35 to 50 inch pounds per UL
486 torque tightening requirements.
