BRANCH CIRCUIT AND FEEDER REQUIREMENTS

SECTION E3706
PANELBOARDS
E3706.1 Panelboard rating. All panelboards shall have a
rating not less than that of the minimum service or feeder
capacity required for the calculated load. (408.30)
E3706.2 Panelboard circuit identification. All circuits and
circuit modifications shall be legibly identified as to their
clear, evident, and specific purpose or use. The identification
shall include an approved degree of detail that allows each
circuit to be distinguished from all others. Spare positions
that contain unused overcurrent devices or switches shall be
described accordingly. The identification shall be included in
a circuit directory located on the face of the panelboard
enclosure or inside the panel door. Circuits shall not be
described in a manner that depends on transient conditions of
occupancy. [408.4(A)]
E3706.3 Panelboard overcurrent protection. In addition to
the requirement of Section E3706.1, a panelboard shall be
protected by an overcurrent protective device having a rating
not greater than that of the panelboard. Such overcurrent pro-
tective device shall be located within or at any point on the
supply side of the panelboard. (408.36)
E3706.4 Grounded conductor terminations. Each
grounded conductor shall terminate within the panelboard on
an individual terminal that is not also used for another con-
ductor, except that grounded conductors of circuits with par-
allel conductors shall be permitted to terminate on a single
terminal where the terminal is identified for connection of
more than one conductor. (408.41 and 408.41 Exception)
E3706.5 Back-fed devices. Plug-in-type overcurrent protec-
tion devices or plug-in-type main lug assemblies that are
back-fed and used to terminate field-installed ungrounded
supply conductors shall be secured in place by an additional
fastener that requires other than a pull to release the device
from the mounting means on the panel. [408.36(D)]
