ManualsBrandsLegrand Wiremold ManualsElectrical120/208-Volt Hardwired Surge Suppressor

A and PB Series Surge Protection Devices (SPD) from Legrand/Wiremold are designed for use at the service entrance,

distribution or branch panel, or at sensitive equipment. Units with an “-A” suffix include remote monitoring contacts; units with

a "-B" suffix include a noise filter. Units with suffix “-AB” include both remote monitoring contacts and noise filter options.

The following tools are required to mount and install the

surge protector:

1. Electric Drill

2. Hole Saw (1 1/8" [29mm] typical) or other knockout

device. (Or use pre-punched knockout on electrical panel.)

3 Wire cutter stripper for #10 AWG wire.

4. Miscellaneous hand tools.

PREPARATION

The following materials are required to mount and install the

surge protector:

1. Nipple (1" [25mm]) close metallic nipple for typical

installations.

2. Connecting wire: #10 AWG stranded.

3. Fasteners appropriate for the wall type where the SPD is

to be mounted. (Unit features built-in mounting holes,

11/64" [4.4mm] diameter.)

CAUTION

• Installation should be performed by a qualified electrician.

• Read all instructions prior to installing this device.

• TO AVOID FIRE, SHOCK, SERIOUS INJURY OR DEATH, TURN OFF POWER TO ELECTRICAL PANEL AND

EQUIPMENT TO BE PROTECTED PRIOR TO INSTALLATION OF THE SURGE PROTECTOR.

• PA and PB Series Surge Protection Devices are not lightning arrestors. They are not designed to

provide protection against direct lightning strikes or against a sustained overvoltage condition.

1. Test and check system voltage to verify proper surge protector selection. TURN OFF POWER TO ELECTRICAL PANEL.

2. Remove the cover from the electrical panel.

3. The SPD must be connected through a dedicated circuit breaker or fused disconnect switch. The breaker (or disconnect

switch) will provide a means of removing power to the unit for maintenance.

Use a 30 amp circuit breaker with an interrupt rating of at least 5,000A RMS, or fused disconnect switch (customer supplied).

Use a three pole breaker for three phase systems, a two pole breaker for 120/240V systems when configuring for

240V, two phase, and a single pole breaker when configuring a 120/240V unit for 120V single phase.

NOTE: Locate the SPD as close to the breaker as possible in order to minimize the connection length between

the panel power lines and the SPD.

4. Unscrew the four (4) nuts on the front of the unit and set them aside. Carefully remove the lid of the SPD; note that the

circuit board is attached. Place the lid with attached board in a safe location where it will not be exposed to dirt,

dust or physical impact.

Legrand/Wiremold electrical systems conform to and should be

properly grounded in compliance with requirements of the current

National Electrical Code or codes administered by local authorities.

All electrical products may present a possible shock or fire

hazard if improperly installed or used. Legrand/Wiremold electrical

products may bear the mark of a Nationally Recognized Testing

Laboratory (NRTL) and should be installed in conformance with current

local and/or the National Electrical Code.

5. Determine the desired location for the SPD. The figure at right illustrates potential locations for the SPD relative to the panel. Hold the SPD case to the panel box and mark the location of the knockout on the SPD case. Make a knockout in the electrical panel where the SPD is to be installed. The knockout should be as close to the breaker feeding the SPD as possible. SPD PANEL SPD SPD SPD 6. Using a hole saw (or knockout device), cut a hole in the SPD enclosure at the entrance location.

120T MODELS Connect Line 1 from panel to Phase 1 on SPD. Connect Line 2 from panel to Phase 2 on SPD. NOTE: When using for 120V only and connecting to only one phase, connect Line 1 from panel to Phase 1 on SPD. Use the supplied jumper wire to connect Phase 1 and Phase 2 on the SPD. 120/240 VOLT SINGLE PHASE SPD Phase 1 120 Volts 240 Volts Primary Voltage Neutral DO NOT USE THE JUMPER WIRE IF YOU ARE CONNECTING 240V. 120 Volts Connect Ground (green wire) from panel to Ground on SPD.

READING STATUS OF PA AND PB SERIES DEVICES Visual Status Protection is indicated by one (1) LED for each phase. An excessive surge, a lightning strike, or a loss of power can cause one or more LEDs to turn off. If power is provided to the SPD unit and one or more LEDs are not illuminated, the unit has been compromised and should be replaced. REMOTE MONITORING For units with remote monitoring contacts option (“-A” suffix), the SPD is equipped with Form C (SPDT) NO/NC dry contacts.
