Electrical Requirements
220V Operation
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.
Extension Cords
Grounding
This machine must be grounded! The electrical
cord supplied with the Model W1679 does not
come with a 220 volt plug. Use a NEMA-style 6-
30 plug and outlet similar to
Figure 6
. Make sure
your ground source is verified!
The SHOP FOX
®
W1689 has a 5 HP, 220V single-
phase sanding motor and a
1
⁄
4
HP, 220V feed
motor. Both of these motors combined draw
approximately 27.8 amps under load.
Use a 30 amp circuit breaker in a circuit that has
wiring rated to handle this amperage draw.
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. Add up the load
ratings of all machines on the circuit. If this
number exceeds the rating of the circuit break-
er or wiring, use a different circuit.
6-30R
6-30P
Figure 6.
This is a typical NEMA-style 6-30 plug
and outlet.
DO NOT replace the circuit breaker with
one rated at a higher amperage or damage
to the circuit may occur.
Any electrical outlet and cir-
cuit 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!
