Section 2: Circuit Requirements; 220/440V 3-Phase - Grizzly G0451 Instruction Manual

SECTION 2: CIRCUIT REQUIREMENTS

220/440V 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 G0451 is prewired for 220V 3-phase
operation. If 440 voltage is required, rewire the
machine according to the instructions on Page 14
and follow the circuit requirements on this page.
Amperage Draw
The Model G0451 has a 10 HP main motor and
a 1 HP scoring blade motor; combined they will
draw the following amps:
Motor Draw at 220V .............................. 28 Amps
Motor Draw at 440V .............................. 14 Amps
Minimum Circuit Requirements
Only connect your machine to a circuit that meets
the requirements below. Check to see if the wires
and circuit breaker in your circuit are capable of
handling the amperage draw from your machine,
as well as any other machines that could be
operating on the same circuit. If you are unsure,
consult a qualified electrician.
220V Circuit .............................................30 Amp
440V Circuit ............................................. 15 Amp
Minimum Cord Requirements
Use the following type of cord to connect your
machine to power (a cord is not provided):
Cord ............................................................4 wire
Gauge .................................................. 10 Gauge
G0451 14" Sliding Table Saw
Connection Type
Because of the high amperage draw from this
machine, we recommend that you hardwire it
directly to your circuit breaker and install a locking
shut-off lever (see Figure 6) near the machine as
a way to quickly disconnect the power and pre-
vent accidental starting.
Figure 6. A power disconnect is preferable to
high current plugs and receptacles.
A fire may occur if your particular electrical
configuration does not comply with local and
state codes. The best way to ensure compli-
ance is to check with your local municipality
or a qualified electrician.
