Switchgear Maintenance
Switchgear Maintenance
(OP)
What is the standard and referrence for existing panelboard and switchgear electrical testing & maintenance? What is the desired interval for this maintenance? I have searched Manufacturers, NFPA, NEC, Nema and found little instruction yet, I am certain there must be an authority with multiple written sources of information on the subject.





RE: Switchgear Maintenance
They have 2 books that tell you how to test everything.
the two books I go buy are the "Acceptance Testing Specifications" - for brand new equipment
"Maintenance Testing Specifications"- routine testing on existing equipment
The typical standard for maintance is once every 1-2 years.

Poor Ave. Good
Low 1 2 2.5
Med .5 1 1.5
High .25 .5 .75
The numbers in the columns are the multiplication factors to apply to typical maintenance frequencies.
This is from the 2001 NETA standard.
