Disconnect
The optional disconnect is a molded case switch with many of
the same features of the circuit breaker. The disconnect comes
standard with a through-the-door handle and mechanism to
disconnect power to the unit prior to opening the door. The
handle can be padlocked in the OFF position while performing
maintenance to the unit.

Terminals
The terminals are spring clamp type. They only require
inserting (see
!
in Figure 123) and clamping the wire to be
stripped, which offers several advantages over screw
terminals. The clamping is done by inserting a flat-bladed
screw driver (up to 9/64" wide). See
#
in Figure 123.
