G5963 Surface Grinder -5-
SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
The motor supplied with the G5963 can be oper-
ated at either 110V or 220V. The motor comes
prewired for 110V. If you wish to operate at 220V,
refer to the section at right.
Under normal use, the motor draws approximate-
ly 7.4 amps @ 110V. We recommend a 15 amp
circuit breaker for 110V operation. This should be
satisfactory for normal use, while providing
enough protection against motor damage caused
by power surges.
Grizzly recommends that the circuit you use
should be dedicated, (i.e., the G5963 should pro-
vide the only draw from that circuit). If frequent
circuit failures occur when using the Surface
Grinder, contact our Service Department or your
local electrical contractor.
220V Operation
The G5963 Surface Grinder motor can be rewired
to operate at 220V. Refer to the wiring diagram
supplied with this manual. If converting to operate
at 220V, the 110V plug must be replaced with a
220V plug. Plugs and receptacles can be pur-
chased at your local hardware store or home cen-
ter. The type of plug you choose will depend upon
the type of 220V outlet used in your installation.
See Figure 2 for a typical plug and outlet. This
plug must be rated for at least 15 amp draw.
It is not necessary to change the switch supplied
with the G5963 for 220V operation.
Under normal 220V use, the motor draws approx-
imately 3.7 amps. We recommend a 10 amp cir-
cuit breaker or a 10 amp slow-blow fuse.
