Weights of Vertical Sections

The following estimates may be used in foundation loading 
calculations. These estimated weights are for each vertical 
section within a shipping group. The estimates are based on
maximum conditions; actual equipment weights will probably
be lower.

Indoor

22” wide with 4 breakers

2850 lbs. (1300kg)

32” wide with 2 breakers

3050 lbs. (1385kg)

32” wide with 1 breaker and fuse carriage

3150 lbs. (1430kg)

Transition box

680 lbs. (310kg)

Outdoor

22” wide with 4 breakers

4200 lbs. (1910kg)

32” wide with 2 breakers

4550 lbs. (2070kg)

32” wide with 1 breaker and fuse carriage

4650 lbs. (2110kg)

Transition box

680 lbs. (310kg)

These estimates should be increased for unusual secondary or
auxiliary equipment, impact loading, or for seismic conditions, 
if required.
