Circuit Breaker Configuration Options

Improper configuration can result in electric shock. All changes from the recommended circuit breaker configuration must meet all National, State,

and Local safety and electrical codes. Consult a qualified electrician before attempting any changes. See page 27 and 28 for correct circuit breaker configuration.

The Electrical Enclosure (DB) circuit breaker configuration described in the tables on the previous page is the recommended configuration.

Sub-Panel Options

Some customer changes are acceptable to accommodate larger loads from auxiliary equipment or a sub-panel. It is suggested that circuit breakers

Component Identification

CB04 be substituted to accommodate larger loads or a sub-panel. The total auxiliary equipment loads added to the configuration must be limited to the system’s available auxiliary current. See Proportioner Models, page 9, for available auxiliary current at 240V, 60Hz.

See the Reactor repair manual for optional circuit breakers and their current ratings. Circuit breakers used must meet UL489 specifications.

Auxiliary Wiring Diagram Options.

The generator supplies power in a 3-wire, single-phase, mid-point neutral wiring configuration. For 240 VAC loads, wire the load across the output terminals of the circuit breaker. For 120 VAC loads, wire the load between the neutral terminal blocks next to the three pole main power switch (CT01) to one pole of the circuit breaker. See electrical diagrams in Reactor repair manual.

Disable LPTCMs For Booster Heat

Both LPTCMs for booster heat must be disabled to allow use of power for additional auxiliary power.

1.Follow Shutdown instructions. See Shutdown, page 63.

2.Refer to Disable Optional Booster Heater Wiring Diagram in the Reactor repair manual.

To replace or repair a circuit breaker, use the following steps:

1.Follow Shutdown instructions. See Shutdown, page 63.

2.Refer to circuit breaker identification table and electrical diagrams in Reactor repair manual.

3.Loosen four screws connecting wires and bus bar to circuit breaker that will be replaced. Disconnect wires.

4.Pull locking tab out 1/4 in. (6mm) and pull circuit breaker away from the din rail. Install new circuit breaker. Insert wires and tighten down all screws.
