Note 1: Two
30
A feeds are typically adequate for a full column of 4 modules (two 30 A feed pairs plus
Logic return).
Note 2: When using dual conduit, the wires must be run in BAT/BR pairs. One pair in one conduit and one
pair plus LRTN in the other conduit.
l
A single or double run of 4 AWG wire from the distribution point to
a
junction box near the pedestal.
10
AWG wire is run from the junction box into the pedestal PDU terminal board.
Legend:
Yes
=
Wire size is adequate for the distance.
No
= Wire size has too high a voltage drop and is inadequate for the distance.
