400 AMP DISCONNECT USER MANUAL
INSTALLATION
Installing S400 Disconnect
The S400 Disconnect is installed between the house service and a portable power distribution system, such as the
PRG Series 400 Power and Data Distribution System. It may also be used to protect a dimmer installation.
CAUTION: Before installing, refer to "Proper Use and Operation" on page 3.
WARNING: Ensure house service main breaker and S400 Disconnect breaker are OFF before connecting
mains power cables. Ground should always be connected first.
To install:
Step 1. At house service main breaker, turn power OFF.
Step 2. Meter voltage at the input of the house disconnect to ensure that all voltages are correct. Phase-to-phase
voltages should be 208 Volts +/- 8 Volts. The voltage between Neutral and Ground should be less than 5
Volts.
CAUTION: If the house breaker has a capacity greater than 400 Amps per phase, the pigtails connecting the
S400 Disconnect cannot be longer than 10 feet.
Step 3. Connect Cam-Lok 5-wire pigtails to house breaker output terminals. Ensure connections are tight to avoid
heating of the connections.
Step 4. Place S400 Disconnect in desired location and remove front and back covers (Figure 3).
