DEVICEIMECHANISM CHECKS
All devices should be checked for
damage (Fig. 43). All necessary repairs
or replacements should be made.
Do not energize damaged
equipment that has not
been
repaired and
verified.
Ensure that safety signs are not
covered or obscured by paint.
Do not remove, cover or
destroy any safety signs.
The setting of any adjustable current
and voltage trip mechanisms should be
verified to the proper values.
NOTE:
Damage from faults can be
reduced if devices used for short circuit
and ground fault protection are chosen
and set to operate at values as close to
minimum as feasible, while allowing
normal transients.
All switches, relays and other operating
mechanisms should be manually
exercised to make certain that they are
properly aligned and operate freely.
Operating mechanisms such as
interlocks, key switches, etc. should be
checked for function as intended for
protection of personnel and equipment.
Overload relays should be checked to
be sure they are selected and adjusted
to the proper settings per the load
nameplate data (Fig. 44).
Power circuit fuses should be selected
and installed in accordance with the
application requirements. Fuses must
be completely inserted in their holders.
