6.3 Circuit Protection
The AC circuit breaker protects the generator set from extreme overload. The AC circuit breaker trips when it detects a fault in the output circuit.
For application and selection information contact an authorized distributor/dealer.
After correcting the fault, reset the AC circuit breaker by placing it in the ON position. Restart the unit. See an authorized service distributor/dealer for AC circuit breaker ratings. The unit’s voltage configuration determines the circuit breaker selection.
Note: Circuit breaker ampere rating and availability are subject to change.
6.3.1Circuit Breaker Considerations
Mounting location. Mount the circuit breaker in the generator set’s junction box.
Sizing. Use the generator set voltage/frequency configuration to determine the circuit breaker amperage. If the circuit breaker was sized for one voltage configuration and later the generator set is reconnected to a different voltage, change the circuit breaker accordingly to provide optimum protection.
Have a qualified electrician or technician install circuit breakers and reconnect the generator set. Comply with all governing standards and codes.
WARNING
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before working on the generator set. Remove the negative
Disabling the generator set. Accidental starting can cause severe injury or death. Before working on the generator set or connected equipment, disable the generator set as follows: (1) Move the generator set master switch to the OFF position. (2) Disconnect the power to the battery charger.
(3)Remove the battery cables, negative
WARNING
Hazardous voltage. Moving rotor.
Can cause severe injury or death.
Operate the generator set only when all guards and electrical enclosures are in place.
Grounding electrical equipment. Hazardous voltage can cause severe injury or death. Electrocution is possible whenever electricity is present. Open the main circuit breakers of all power sources before servicing the equipment. Configure the installation to electrically ground the generator set, transfer switch, and related equipment and electrical circuits to comply with applicable codes and standards. Never contact electrical leads or appliances when standing in water or on wet ground because these conditions increase the risk of electrocution.
Short circuits. Hazardous voltage/current can cause severe injury or death. Short circuits can cause bodily injury and/or equipment damage. Do not contact electrical connections with tools or jewelry while making adjustments or repairs. Remove all jewelry before servicing the equipment.
Electrical backfeed to the utility. Hazardous backfeed voltage can cause severe injury or death. Connect the generator set to the building/campground electrical system only through an approved device and after the building/campground main switch is opened. Backfeed connections can cause severe injury or death to utility personnel working on power lines and/or personnel near the work area. Some states and localities prohibit unauthorized connection to the utility electrical system. Install a transfer switch to prevent interconnection of the generator set power and other sources of power.
