Section 11: Certifications
Section 12: Maintenance Information
Electrical and mechanical inspection of all components must
be performed on a regularly scheduled basis, determined by
the environment and frequency of use. It is recommended
that inspection be performed a minimum of once a year.
1.
Inspect contact crimp locations for security.
2.
Clean exterior surfaces, making sure nameplates
remain legible.
3.
Check tightness of all shell parts before using.
4.
Check contacts for signs of excessive burning or arcing
and replace if necessary.
5.
Check shell parts for damage to threads and skirts and
replace if necessary.
In addition to these required maintenance procedures,
we recommend an Electrical Preventative
Maintenance Program as described in the
