Model G3620/G9966

440V Operation

The Model G3620/G9966 Bandsaw is pre-wired for 3-phase, 220V operation. Under normal use, the 712 HP motor for this model draws approxi- mately 19 amps. We recommend using a 25 amp circuit, including a 25 amp circuit breaker and wir- ing rated for at least 25 amps. If frequent circuit breaker failures occur when using the bandsaw, contact our service department.

This bandsaw must be connected to its own dedicated circuit. It should not share a circuit with any other machine. A standard 3-pole breaker is necessary for use with the Model G9963.

We recommend using a NEMA-style L15-30 plug and outlet, similar to Figure 2. You may also “hard-wire” the bandsaw directly to your panel, provided you place a disconnect near the machine. Check the electrical codes in your area for specifics on wiring requirements.

The Model G3620/G9966 Bandsaw is furnished with a 712 HP 3-phase motor that can be wired to 440V. Under normal use, this motor draws approximately 10 amps at 440V. If 440V opera- tion is desired, we recommend using a 15 amp circuit that includes the appropriate wiring and circuit breaker. If frequent circuit failures occur when using the bandsaw, contact our service department.

The bandsaw must be connected to its own dedi- cated 10A circuit. It should not share a circuit with any other machine. A standard 3-pole breaker is necessary for 440V use.

This bandsaw is not supplied with a power plug. We recommend “hard-wiring” the bandsaw to the power source, provided you place a locking shut off switch near the machine to disconnect the power. Check the electrical codes in your area for specifics on wiring requirements.

If you convert the bandsaw to 440V, the stock mag switch must be replaced with a differ- ent mag switch specifically for 440V use. The 440 mag switch is not included with your bandsaw.
