Sizing and dimensional data

Typical AC switchgear sections, 635V maximum,
50/60 Hz
Switchgear section and line-up sizing
AKD-10 indoor low voltage switchgear height is 92" (97" over
the top wiring trough and 103.5" over the optional breaker
hoist). The available breaker stacking space is 84". Optional
78"-high indoor equipment with a breaker stacking space of
70" is also available (contact factory for details).

Breaker frame size and type determine the width of the
breaker sections and also the minimum depth of the
switchgear line-up. Refer to Tables 31.1 and 31.2 for properly
sizing AKD-10 line-ups. The depth of the entire line-up is
determined by the deepest device in the line-up. For example,
a line-up with a WPS-20 breaker with a fuse roll-out (depth -
60") and WPF-08 breakers (depth - 67") would be a minimum
of 67" deep — the WPF-08 being the deepest device. Also
refer to the section arrangements on the following pages for
available breaker stacking configurations.
