120 V GFCI DUPLEX RECEPTACLES
A GFCI (Ground Fault Circuit Interrupter) electrical receptacle is a device to protect against electric shock should a piece of defective equipment connected to it develop a ground fault. If this situation should occur, the GFCI will trip, removing voltage from the output of the receptacle. If a GFCI receptacle is tripped see the MAINTENANCE section for detailed information on testing and resetting it. A GFCI receptacle should be properly tested at least once every month.
The 120V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs.
The current rating of any plug used with the system must be at least equal to the current load through the associated receptacle.
480 Volt 3 Phase Receptacle with Ground
The 480 volt receptacle can supply 12.6 amps of 3 phase power, or up to 15 amps of single phase power. A NEMA plug
If 480 volt single phase load is to be run, the X lead must be one of the leads in the circuit in order for the automatic idle to function. Using a NEMA plug L16- 20P, connect either X and Y or X and Z to the recep- tacle, as well as the machine ground.
All auxiliary power is protected by circuit breakers with the following values:
The 120V has 20 amp circuit breakers for each duplex receptacle. The 240V has 50 amp circuit breakers for each hot lead going the 240V receptacle. The 480V 3 phase circuit breakers / switch has a 3 phase, 15 amp circuit breaker.
Ground Wire
Periodically check the ground wire at plugs, power cords and auxiliary loads to ensure that the grounding circuit is intact and connected.
MOTOR STARTING
Most 1.5 hp AC single phase motors can be started if there is no load on the motor or other load connected to the machine, since the full load current rating of a
1.5hp motor is approximately 20 amperes (10 amperes for 240 volt motors). The motor may be run at full load when plugged into only one side of the duplex receptacle. Larger motors through 2 hp can be run provided the receptacle rating as previously stated is not exceeded. This may necessitate 240V operation only.
The 480 volt 3 phase output of the RANGER 3 PHASE is capable of running most 480VAC 3 phase motors up to 10HP. A 10HP motor must be started with no load on the motor and no other load connect- ed to the machine, since the full load current of a 10HP 480VAC 3 phase motor is approximately 12.5 amps. Refer to the reconnect phase output to any load, the ground at the 3 phase receptacle is NOT the neutral of 3 phase connection, and should under no circumstance be connected to the neutral of any 3 phase load.
