21. Repeat Steps 18 through 20 to power up Side B.
A
and
B
power LEDs must both be green.
22.
Make sure none of the fuse positions contain
operable fuses.
23. For TPA output wiring, crimp single-hole lugs onto
one end of the #18 to #6 AWG copper output wires,
as required by NEC. (Work with one output wire
at a time.)
24. Clean the panel terminals and lugs with a non-abrasive,
non-metallic pad.
25.
If required, lightly coat anti-oxidant on the lugs and
output
BATT
and
RTN
terminals.
26. Connect the lug to the terminals, as shown in
Figure 7. (NEC specifies only one lug and load at
each output terminal.)
27.
Tighten the nuts to 20 in.-lb (~2.3 N•m).
28.
Connect the other end of the output wire to load.
29. For GMT output wiring, use #22 to #12 AWG
copper wire. (Work with one wire at a time.) At
the panel end of the wire, crimp a single-hole
ring or fork lug, as required by NEC.
30.
Clean the panel terminals and lug (if applicable)
with a non-abrasive, non-metallic pad.
31.
If required, lightly coat anti-oxidant on lug/wire and
output
BATT
and
RTN
terminals.
32. Connect to the terminals, as shown in Figure 8.
(NEC specifies only one load at each output terminal.)
33. Tighten the panhead screws to no more than 6.3
in.lb (~0.7 N•m).
34.
Connect the other end of the output wire to load.
ALERT
!
ALERT! GMT fuses have a small inherent electrical
resistance resulting in a small inherent power loss.
For this reason, the GMT fuse manufacturer
recommends that the load for GMT fuses up to and
including 7.5A not exceed 80% of the fuse rating
and that the load for GMT fuse sizes between 10A
and 15A not exceed 70% of the fuse rating. For
example, the load for a 15A GMT fuse should not
exceed 10.5A (15A x .70 = 10.5A).
