SECTION 2: CIRCUIT REQUIREMENTS

220V 3-Phase

440V 3-Phase

 

 

 

Serious personal injury could occur if you connect your machine to the power source before you have completed the set up pro- cess. DO NOT connect the machine to the power source until instructed to do so.

Wiring

The Model G0503 is prewired for 220V 3-phase operation.

Amperage Draw

The Model G0503 has a 20 HP main motor and a 2 HP hydraulic pump motor that will draw the following amps at 220V 3-phase:

Main Motor

48

Amps

Hydraulic Pump Motor

6

Amps

Circuit Breaker Requirements

Install the machine on a dedicated circuit to reduce the possibility of overloading the circuit and tripping the circuit breaker. If the circuit breaker trips and the circuit is of the correct load capacity, have the circuit inspected by a qualified electrician. Never use a larger circuit breaker than stated below, or you will increase the risk of fire.

Circuit Breaker

60 Amp

Minimum Wire Requirements

 

For 220V 3-phase operation, use the following type of wire:

Wire

6 GA. Copper

We recommend running THWN/THHN grade insulated wire through rigid conduit and hardwir- ing into a locking power disconnect. Consult a qualified electrician for information on local and national electrical codes.
