Primary and secondary current injection testing
Primary and secondary current injection testing
(OP)
For small molded case breaker frames rated 400 amps and below, would you typically test with primary and secondary injection? NETA ATS 2004 list these test under molded case type breakers but I am hearing from co workers that you do not typically perform these tests on molded case breakers.
Thanks.

RE: Primary and secondary current injection testing
As with all things one must weigh risk and reward. Most of my customers will not spend $1000 to test a $600 50A molded case breaker that feeds the wash room.
Some will spend that the money because they were told to do it.
Others would just buy a spare breaker.
If the 50A breaker feeds the lube oil pump to a $500,000 machine one may look at it in a different light.

If the job requires testing to NETA specs then primary injection is required.
