ELECTRICAL REQUIREMENTS
220V Operation
The Shop Fox
®
Model W1687 requires a 220V sin-
gle-phase power source for operation. Also, you
will need a NEMA-style L6-20 plug as shown in
Figure 6. The motor supplied with your new
machine is rated at 3 HP and will draw approxi-
mately 18 amps during 220 volt operation. When
choosing a receptacle for this machine, consider
using one with a 20 amp circuit breaker or fuse.
Keep in mind that a circuit being used by other
machines or tools at the same time will add to
the total load being applied to the circuit. Add
up the load ratings of all machines on the cir-
cuit. If this number exceeds the rating of the
circuit wires or circuit breaker/fuse, use a dif-
ferent circuit.
Extension Cords
We do not recommend using an extension cord
for 220V equipment. Instead, arrange the place-
ment of your machinery and installed wiring to
eliminate the need for extension cords. If you
must use an extension cord, make sure it is
rated Hard Service (grade S) or better. The
extension cord must always contain a ground
wire and plug pin. Always repair or replace
extension cords when they become worn or
damaged.
Grounding
This machine must be grounded! The electrical
cord supplied with the Model W1687 does not
come with a 220 volt plug. Use a plug with a
ground pin. If your receptacle does not accom-
modate a ground pin, have it replaced by a qual-
ified electrician or have an appropriate adapter
installed and grounded properly. An adapter
with a grounding wire does not guarantee the
machine will be grounded. A ground source must
be verified.
NOTICE
Never replace the circuit breaker with one
rated at a higher amperage or damage to the
circuit may occur.

Any electrical receptacle
and circuit that you plug
your machine into must be
grounded. Never remove
the grounding pin from any
plug and always make sure
all wiring to the machine is
grounded before operating.
Serious injury may occur if
this warning is ignored!
