Hardware for connecting power input cables to the BIP

The cables that input power to the rear of the breaker interface panel (BIP) can
be connected by one of the following methods.
• directly to the studs on the rear of the BIP
• indirectly through one of the power-and-ground assemblies (described in
Using an optional power-and-ground assembly (page
See the figure
connections include the following parts for each BIM:
• one pair of studs for connecting one dc power input cable and one return,
that is, one feed
• one power input stud with an anti-rotation mate for each 2-hole lug
• one lug per pair of studs that is a 90-degree offset narrow-tongued 2-hole
lug sized No. 2/0 AWG; the lug is oversized so that it accommodates the
different thicknesses of 1/0 AWG (53.49 mm
manufacturers, for example, with a 0.625 pitch
Attention: When using power input cables that are thinner than 1/0 AWG,
you must provide lugs matched to the cable gauge. When powering from an
Astec MFA150 power system of ac rectifiers, the appropriately sized lugs for
power cable installation are specified for the installation.
• one insulating boot per pair of studs to safely cover the studs, the end of
the 1/0 AWG cable, and the lug
Attention: When using power input cables that are thinner than 1/0 AWG,
the same insulating boot is used and the gap is addressed by the procedure
to connect each cable.
