GROUND CONNECTIONS

The circuit breaker must be grounded in

accordance with the requirements of the National

Electrical Code, Article 250 or applicable local

standards.

Proper grounding

connections must be made

to the circuit breaker before

incoming power is applied.

It is very important that the circuit breaker and its

enclosure be adequately grounded to protect the

operator from injury in the event of short circuits

or other abnormal occurences and to ensure that

the metal parts of the equipment, other than live

parts, remain at ground potential.

For U and MU type circuit breakers, the ground

terminal is on the left side of the operating

mechanism as viewed from the rear of the

breaker. To make the ground connection, first

remove the fastening M6 hex head bolt and

crimp-on terminal (provided with the breaker)

and crimp the terminal to the end of the ground

wire (Fig. 18). Then, reattach the terminal using

the same bolt previously removed and torque to

50-65 kgf-cm (43-56 in-lb).

For L and ML type circuit breakers, the ground

terminal is on the left side of the terminal block

as viewed from the rear of the breaker (Fig. 19).

The same instructions as for the U and MU

breaker above should be followed to attach the

ground wire.
