FeederTap Fusible Switches
Fusible feeder switches, 30A through 200A, are mounted in
plug-in units. Switches above 200A are fixed mounted and
consist of molded-case switches and separate fuse blocks.
Dual-mounted fusible switches are available, 30A and 60A,
with clips of same rating. Fuse clips are Class RK dimensions
for 30-600A.
FeederTap Circuit Breakers
These breakers are thermal magnetic type and feed
lighting or power circuits. 125A and 250A frame
breakers are mounted in plug-in units. Higher rated
breakers are fixed mounted. (See chart on page G6
for short circuit ratings and type of circuit breakers
available.)
Dual mounted 125A frame breakers may be mounted
in a 12” plug-in unit with a common door.

Distribution Units
A Motor Control Center is principally intended to
house multiple combination starters for the control of
electrical motors. It is often convenient to include a
limited number of power distribution units.
Transformer Protection - Lighting and Master
Control
Primary protection is required, per NEC sizes as follows: (lp = transformer primary currents.)
125% lp for lp greater than 9A.
167% lp for lp less than 9A.
300% lp for lp less than 2A.
In addition to primary protection, secondary protection must be supplied if the transformer secondary is
3 or 4 wire (dual voltage). Secondary protection is
not required if the transformer is 2 wire (single voltage secondary).

• Transformers
• Feeder tap circuit breakers
• Feeder tap fusible disconnects
• Lighting panels
3 Phase Transformers:
All three phase transformers require 20” deep sections, must
be mounted in the bottom, and will not have vertical bus in
that compartment. Refer to page B22 for conduit entry.
All 3KVA and larger single phase and all three phase transformers are mounted approximately 5 inches above the
structure base channel sills.
