FeederTap Circuit Breakers These breakers are thermal magnetic type and feedlighting or power circuits. 125A and 250A framebreakers are mounted in plug-in units. Higher ratedbreakers are fixed mounted. (See chart on page G6for short circuit ratings and type of circuit breakersavailable.)
Dual mounted 125A frame breakers may be mountedin a 12” plug-in unit with a common door.
FeederTap Fusible Switches Fusible feeder switches, 30A through 200A, are mounted inplug-in units. Switches above 200A are fixed mounted andconsist 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 dimensionsfor 30-600A.

Distribution Units
A Motor Control Center is principally intended tohouse multiple combination starters for the control ofelectrical motors. It is often convenient to include alimited number of power distribution units.
These units consist of the following: • Transformers • Feeder tap circuit breakers • Feeder tap fusible disconnects • Lighting panels
Transformer Protection - Lighting and MasterControl Primary protection is required, per NEC sizes as fol-lows: (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 protec-tion must be supplied if the transformer secondary is3 or 4 wire (dual voltage). Secondary protection isnot required if the transformer is 2 wire (single volt-age secondary).

Transformer Ratings and Space Requirements Single Phase Transformers:1KVA and 2KVA sizes with 120V secondary can bemountedin a single 12” plug-in unit with a primarycircuit breaker or fusible disconnect.
3KVA and larger sizes are mounted in bottom of sec-tion. 20KVA or larger sizes require 20” deep sections.
3 Phase Transformers:All three phase transformers require 20” deep sections, mustbe mounted in the bottom, and will not have vertical bus inthat compartment. Refer to page B22 for conduit entry.
All 3KVA and larger single phase and all three phase trans-formers are mounted approximately 5 inches above thestructure base channel sills.
