Connect control in accordance with National Electric Code requirements and other local
codes that apply. The KBRG-212D does not contain AC line or armature fusing. It is
recommended that a 20 Amp fuse or circuit breaker be installed on each AC line
conductor not at ground potential. Connect control, in accordance with illustrations in this
section. A separate AC line switch or contactor must be connected as a disconnect switch
so that contacts open each ungrounded conductor. In addition, Table 6, details the
connection, wiring and torque information.

6.1 AC Line Connection – Connect the AC line to L1 and L2 terminals of TB1 as
