-12- G0501 Sliding Table Saw
The Model G0501 can be rewired for 440V oper-
ation. This rewiring job consists of disconnecting
the saw from the power source, changing the
connections on the voltage transformer, changing
the overload relays for the cutting motor and
scoring motor, and rewiring the cutting motor and
scoring motor.
The necessary overload relays for this procedure
can be purchased in the Model G0501 440V
Conversion Kit by calling our customer service
number at (800) 523-4777.
This procedure takes moderate electrical skill and
the rewiring job must be inspected by a licensed
electrician before the saw is connected to the
power source. Also, the motors can be accessed
easier for rewiring if the blade is moved to 0˚ (90˚
to table) before beginning.
To rewire the Model G0501 for 440V opera-
tion:
1. Disconnect the saw from the power source!
2. Open the electrical panel and locate the volt-
age transformer shown in Figure 2.

connected to 440V location.
3. At the voltage transformer, remove the wire
that leads to the “220” terminal and connect
that wire to the “440” terminal (see Figure 3).
4. Remove the main motor overload relay (RH-
18/26 21-31A) and replace with the 440V
overload relay (RH-18/15 12-18A) that was
included with the Grizzly 440V conversion
kit. Set the overload relay dial to 13A.
5. Remove the scoring motor overload relay
(RH10E/3C 2.4-3.6A) and replace with the
440V overload relay (RH10E/1.7C 1.3-2A)
from the conversion kit. Set the overload
relay dial to 1.7A.
6. Open the motor cabinet door and remove the
motor wiring caps from the main motor and
the scoring motor.
7. Rewire the motors as shown on the diagrams
that are placed on the inside of the motor
wiring caps. Note—The diagram labeled
“Higher” is the correct wiring for 440V.
