The section frames are connected as shown in Figure 40. The joining of the sections contains two bolted connections on the
top and bottom depth-frame members. In addition, two bolted connections are made on each vertical frame member. The
vertical connections are located one-third and two-thirds up from the bottom of the switchboard (for a 90” switchboard, the
connections are made at 30” and 60” off the ground).
