Abstract
Abstract A box of the switchboard is generally of floor-to-ceiling height and contains an upper bussed current transformer compartment with provision for a watt-hour meter. A lower compartment contains a horizontally extending stack of bus bars fed by a main circuit breaker disposed adjacent one end and on the upper side of the stack. Branch circuit breakers for relatively large loads may be plugged on the bus bars from the lower side of the stack and the load wires extended therefrom toward the bottom of the box. If desired, branch circuit breakers for relatively small loads can be accommodated by distribution panels plugged on the bus bars adjacent the other end of stack from the main circuit breaker. The smaller branch circuit breakers can then be plugged on the distribution panels and the load wires run therefrom toward a side of the box.

Claim 1
Independent Claim
220 words
A service section switchboard comprising a box having a rear wall and a pair of opposite side walls, a mounting pan in the box generally parallel to and spaced from the rear wall and also spaced from one of the side walls to provide a vertically extending wiring trough along the one side wall and spaced from the bottom of the box to provide a horizontally extending wiring trough along the bottom of the box, a plurality of flat, elongated, flatwise aligned, horizontally extending bus bars mounted on the mounting pan with flat sides parallel to the rear wall of the box, a multipole main circuit breaker mounted in the box above the bus bars and adjacent the other of the side walls, poles of the main circuit breaker being electrically connected respectively to the bus bars, means for mounting relatively small branch circuit breakers in the box some with line terminals electrically connected to one of the bus bars and others with line terminals electrically connected to another of the bus bars and all with load terminals facing the vertically extending wiring trough, and means for mounting relatively large branch circuit breakers in the box below the bus bars with line terminals electrically connected respectively to the bus bars and with load terminals facing the horizontally extending wiring trough.
