Acceptable manufacturers: Cutler Hammer / Square D.
3.1
INSTALLATION
.1
Locate panelboards as indicated and mount securely, plumb, true and square, to adjoining
surfaces.
.2
Install surface-mounted panelboards on U-channels. Where practical, group panelboards on
common length of U-channel.
.3
Mount panelboards to height indicated in Section 16050, unless otherwise indicated.
.4
Connect loads to circuits as indicated.
.5

a)
split wired parking or kitchen countertop receptacles.
b)
balanced three-phase lighting circuits feeding fluorescent and/or incandescent
sources only.
c)
Convenience receptacle circuits in corridors or stairwells. Where a common neutral
is acceptable (a, b, or c above), they shall be shared by vertically adjacent breakers.
Neutral conductors shall be identified with Mylar/cloth wire markers showing the
circuit number of all circuits sharing the neutral. Wire markers for each phase
conductor shall be provided.
.6

centre, and right hand panelboard busses represent Phases A, B and C, respectively. All
indicating meters shall be identified to this sequence.
.10
Panels shall be complete with 10% spare breakers and 10% space (and mounting hardware)
based on Panel capacity for future breakers.
