• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or NOM-029-STPS.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this equipment before working on or inside equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
  Failure to follow these instructions will result in death or serious injury.

Double Row Bus Construction
Tandem circuit breaker type HOMT may be installed in combination service entrance devices where the bus bar connector has a slot at the centerline of the desired pole space. See Figure 1.

NOTICE

HAZARD OF EQUIPMENT DAMAGE
Do not use excessive force to install a HOMT tandem circuit breaker where no connector slot is provided. See Figure 1.
Failure to follow this instruction can result in damage to the circuit breaker case.

Note: Tighten all electrical connections to specifications. See lug torque data chart on combination service entrance device wiring diagram for torque specifications.  See circuit breaker marking for lug torque specifications.

Single Row Bus Construction

NOTICE

HAZARD OF EQUIPMENT DAMAGE
Tandem circuit breaker type HOMT may only be installed in combination service entrance devices where the bus bar connector has a configuration as in Figure 3.
Failure to follow this instruction can result in equipment damage.

Use only Homelike™ circuit breakers and replacement parts with this product. Use of other components voids the warranty, may void the UL listing and may result in personal injury or equipment damage. Refer to device markings for specific restrictions.
Failure to follow this instruction can result in personal injury or equipment damage.

Circuit Breaker Installation

1. Turn off circuit breaker.
2. Insert wire terminal end of circuit breaker into mounting hook.
3. Push circuit breaker inward until plug-on jaws plug securely on to bus bar connector.
4. Install wires.

Identify Circuits
Identify branch circuits on directory label or directory stickers.
Energize the Circuit
Note: Before energizing combination service entrance devices, turn main and branch circuit breakers to the OFF position.

1. Turned on power to the combination service entrance device.
2. Turn main circuit breaker ON.
3. Turn on branch circuit breakers.

Handle at mid position indicates the circuit breaker is tripped. To reset, move handle to the off position and then to the on position.

Removal of Circuit Breakers

1. Turn circuit breakers OFF.
2. Remove wires.
3. Disconnect plug-on jaws from bus bar connection by pulling circuit breaker outward until it disengages from mounting hook.
