Size wire for 20 amp circuit. For single phase
4HP motor wire for 30 amp circuit. See Motor
Operating Data Table.
Never operate the motor on line
voltage less than 208V. Motor damage may occur.
IMPORTANT: Use separate circuit for each power
unit. Protect each circuit with time delay fuse or
circuit breaker. For single phase 208-230V, use 20
amp fuse. For single phase 4HP motor use 30 amp
fuse. Three phase 208-240V, use 20 amp fuse. For
three phase 400V and above, use 10 amp fuse. For
wiring see Fig. 15, Fig. 16, and Fig.16b. All wiring
must comply with NEC and all local electrical
codes.

NOTE: Assure cord used for connection
between the overhead switch and power
unit is of the type specified in:
UL201, Sections 10.1.1.3 & 10.1.1.4
(Example: SO, G, STO) Size for 25 amp
circuit. See UL 201, Section 15 for proper
wiring requirements for this connection.
