EMP Shield (120/240V, single -phase version), (120/208V, 3-phase version) or (277/480V, 3-phase version) Branch Panel Mounted devices have been designed to protect residential, small commercial, and industrial establishments from high voltage transients. The standard J-Box plastic enclosure with integrated conduit port simplifies mounting in typical frame construction environments, and provides convenient connection means to
System Voltage Requirements
1.Measure panel voltage, L-N, to determine the system voltage. System voltage must not exceed the specified maximum continuous RMS voltage on the EMP Shield device label.
Location and Mounting
2. Remove the circuit breaker panel cover and determine the breaker-panel wiring entry point relative to
3. For surface-mount circuit breaker panels, the EMP Shield device may be connected using rigid conduit to any conduit port.
4. For non-surface mount installations, secure the EMP Shield to the support stud in the wall by cutting a 6 x 6-inch mounting hole.
The EMP Shield (TB – Version) comes with a terminal block 12 AWG COPPER WIRE ONLY. For wire range Solid or Stranded 12 AWG, tighten to Torque 25 in-lbs.
The EMP Shield (W – version) comes with preconnected 12 AWG COPPER WIRE. Tighten to Torque 25 in-lbs.
1. WARNING: TO AVOID FIRE, SHOCK OR DEATH, TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT POWER IS OFF BEFORE WIRING!
2. Connect wire leads to terminal block: BLACK, RED, BLUE to PHASES, WHITE to NEUTRAL and GREEN to GROUND. See Figures 1 through 4 on
3. Thread the EMP Shield device’s wire leads through the conduit to
4. Secure the EMP Shield cover with the screws removed previously.
5. Select circuit breakers as close as possible to each service entrance lug. Twenty-Amp (20A) circuit breakers are
NOTE: Do not connect EMP Shield leads directly to service entrance lugs. This may result in fire, shock or death.
6. Lead lengths should be as short as possible. Connect the BLACK, RED, BLUE leads to each PHASE through the selected circuit breakers. Connect the WHITE lead to NEUTRAL as close as possible to NEUTRAL entrance service lug.
NOTE: Avoid long loops and do not coil extra lead wire.
7. Replace the circuit breaker panel cover. Installation is complete.
