36. Make sure the load devices are switched off 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 the TPA fuse carrier
and insert the operable fuse, as shown in
Figure 14.
• For a GMT fuse, pull out the dummy fuse and
insert the operable fuse, as shown in Figure 15.
• Test the power and polarity at the input of each
equipment load.
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 20A 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).
