To field install the NFD shaft and handle (see Fig.46 and 47):
1. Remove the unit front panel (see Fig. 2-4).
2. Remove (3) hex screws on the NFD enclosure - (2) on the
face of the cover and (1) on the left side cover.
3. Remove the front cover of the NFD enclosure.
4. Make sure the NFD shipped from the factory is at OFF posi-
tion (the arrow on the black handle knob is at OFF).
5. Insert the shaft with the cross pin on the top of the shaft in
the horizontal position.
6. For sizes 08 to 14, measure from the tip of the shaft to the top
surface of the black pointer; the measurement should be 3.75
to 3.88 in. (95 to 99 mm). For size 16, measure the tip of the
shaft to the top surface of the pointer to be 3.75 to 3.88 in.
(95 to 99 mm) for 80A and 100A NFD and 3.43 to 3.56 in.
(87 to 90 mm) for 200A NFD.
7. Tighten the locking screw to secure the shaft to the NFD.
8. Turn the handle to the OFF position with red arrow pointing
at OFF.
9. Install the handle on to the painted cover horizontally with
the red arrow pointing to the left.
10. Secure the handle to the painted cover with (2) screws and

UNITS WITHOUT FACTORY-INSTALLED NON-
FUSED DISCONNECT —
When installing units, provide a
disconnect switch per NEC (National Electrical Code) of ade-

ALL UNITS — Field wiring must comply with NEC and all lo-
cal codes. Size wire based on MCA (Minimum Circuit Amps) on
the unit informative plate. See Fig. 37 and 38 and the unit label di-
agram for power wiring connections to the unit power terminal
blocks and equipment ground. Maximum wire size is #2 ga AWG
per pole.
Provide a ground-fault and short-circuit over-current protection
device (fuse or breaker) per NEC Article 440 (or local codes). Re-
fer to unit informative data plate for MOCP (Maximum Over-cur-
rent Protection) device size.
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is to be
connected to a 208-v power supply, the control transformer must
be rewired by moving the black wire with the 1 /
4
-in. female
spade connector from the 230-v connection and moving it to the
200-v 1 /
4
-in. male terminal on the primary side of the transform-
er. Refer to unit label diagram for additional information.
