nameplate and table in Fig. 2-1. Torque mounting screws
to 30-35 Ib-ft. (41-47 Nm).
Re-install load end and line end covers and secure with
pan head screws provided. Torque large screws to 35-45
Ib-in. (4.0-5.0 Nm) and small screws to 24-30 Ib-in
(2.7-3.4 Nm). When prospective fault currents of cabled
