*We recommend that you size fuses such that they do
not run at more than 70% of their rating. Thus a 20A fuse
should not be run at more than 14A.
**The sum of the fuse ratings must not exceed the bus
rating, or input fuse rating
Compatible lugs for Input Block
2 hole compression lugs for 1/4” studs on
5/8” centers (torque 5.5ft-lbs) example;
Panduit®
LCD1-14A 1awg wire
LCD2-14A 2awg wire
LCD4-14A 4awg wire
LCD6-14A 6awg wire
LCD8-14A 8awg wire
The Panduit® CT-1700 crimping tool can be
used for securing wire to any of these lugs.
Input wiring should be rated 90°C or better
and fused at 125% of total Bus current (ie: up
to 125Amps MAX rated input fuse/breaker)
Output lugs
(locking fork recommended):
Ring or fork for #6 screw (up to 10awg).
(Torque to 9 in-lbs, use wire rated 90°C or
better.
NOTE:
If fuse size is not specified in the
equipment manual, fuses should be selected
such that they do not run at more than 70%
of their rating. When installing fuses, the
sum of the fuses installed in each bus should
not exceed the bus rating (100 Amps) or
input fuse rating.
Chassis Grounding:
Depending on the bus input current being supplied, the chassis bonding
conductor used should meet the minimum requirements. Please note that 100 A is the maximum
allowable bus current rating.
