23. For output wiring, crimp single-hole lugs onto one
end of #16 AWG to #8 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-abra-
sive, non-metallic pad.
25. Remove the panhead screw on the terminal
block.
26. Telect recommends a light coating of anti-oxidant
on lugs and output
BATT
and
RTN
terminals before
connecting lugs to terminals, as shown in Figure
9. (NEC specifi es only one lug and load at each
output terminal.)
27. Tighten the screw to 15 in.-lb (~1.69 N•m).

ALERT
!
ALERT! Local electrical and operating company
guidelines recommend that the individual load not
exceed 80% of over-current device capacity (for
example, 50A TPA fuse x .80 = 40A max. load). Total
load for all TPA & GMT outputs on each side must
not exceed 150A.
28. Connect the other end of the output wire to load.
29. Make sure the load devices are disabled and then
install the fuses.
NOTE: Under load, TPA modules are disconnect
devices only and must not be used to reconnect
power to enabled equipment loads. Reconnecting
a TPA module under power with an enabled load
may damage the TPA module.
• For a TPA fuse, pull out TPA fuse carrier and
insert operable fuse, as shown in “Installing TPA
Fuses” illustration.
