Note 1: Two 30-amp feeds are typically adequate for a column with four modules (five wires
total-two 30-amp battery/battery return pairs plus logic return).
Note 2: When using dual conduit, the wires must be run in battery/battery return pairs, with
one pair in one conduit and the other pair, plus logic return, in the other conduit.
Note 3: Five single runs of #4 AWG wire are used from the distribution point to the NT6D53
junction box near the pedestal; #10 AWG wire in a single conduit (supplied with the junction
box) is run from the junction box to the pedestal.
Note 4: Five double runs of #4 AWG wire are used from the distribution point to the
NT6D53 junction box near the pedestal; #10 AWG wire in a single conduit (supplied with the
junction box) is run from the junction box to the pedestal.
Legend: Yes = Wire size is adequate for the distance
No = Wire size has too high a voltage drop and is inadequate for the distance.
