Looking for some thoughts on the pros and cons of primary injection testing of circuit breakers. Should it be done and, if so, how frequently? I'm also interested in thoughts on the validity and thoroughness of secondary injection vs. primary injection and what methods might be most effective and practical on LV (<600v) and MV breakers.
