ELECTRICAL REQUIREMENTS
We do not recommend using an extension cord
with 220V equipment because the cord can
generate heat that may cause fire or circuit
damage. If you must use an extension cord, use
the guidelines listed below and
TABLE 2
to
determine the correct cord length and gauge.
The amp rating of both motors combined is 27
amps at normal operation; however, the amperage
will increase or decrease depending on the load
you apply on the Double Drum Sander.
•Use a Standard Service (Grade S) cord or
better
•Use a cord that is 50 feet or less only
•Use a cord with a NEMA-style L6-30 plug
•Use an undamaged cord only

220V Operation
The
SHOP FOX
®
Model W1678 Drum Sander uses
one 220 VAC single-phase motor. This sanding
drum motor is rated at 5 HP and draws
approximately 25 amps under a normal sanding
load.The
1
⁄
3
HP varyable speed conveyor motor
uses 60 VDC and draws approximately 2 amps.
Refer to the wiring diagram on
Pages
35
and
36,
and hard wire the power supply to the sander, or
use a NEMA-style L6-30 plug and receptacle as
shown in
Figure 9
. In either case, the supply
circuit, circuit breaker, or fuse must be able to
carry a load of at least 27 Amps. Remember
other machines using this circuit add to the total
electrical load applied to the circuit. If this total
amperage load exceeds the amperage rating of
the circuit breaker or fuse, use a different
circuit with a higher amperage rating.
DO NOT modify an existing low-amperage circuit
by only replacing the circuit breaker with a
breaker rated for a higher amperage. The
breaker and the complete circuit must be
replaced by a qualified electrician.

Grounding
Ground this machine!
The electrical cord
supplied with the Model W1678 does not come
with a 220 volt plug. Use a plug with a ground
pin as shown in
Figure 9
. If your receptacle does
not accommodate a NEMA-style L6-30 plug with
a ground pin, have the receptacle replaced by a
qualified electrician or have an appropriate
adapter installed and grounded properly.
Remember, an adapter with a grounding wire
does not guarantee the machine will be grounded.
A ground source must always be verified in the
electrical circuit within the wall or conduit.
Any electrical outlet and
circuit that you plug your
machine into must be
grounded. Serious injury or
fire may occur if this warning
is ignored!
