Grizzly G0503 instruction manual Circuit Requirements, 220V 3-Phase 440V 3-Phase, Amperage Draw

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.
