Pigtail grounding
I believe that requirements to sit for Inspector certifications-be it "ncpcci"certs[res 1@2,general,plan review] or the more recent iaei/nfpa designations [in place since approx 2000] listed as Master electrical Inspector,or Residential Electrical Inspector,are similar-7yrs as an electrician before consideration.
Exception-P.E.'s are granted an exception waiving the 7yr field requirement.
Understand that there are guys who can spend 14 yrs in the field and still be useless?
and there are guys who may come in Under the PE exemption and be as at home as if they were born in the field.
Point of my reply being that any GOOD inspector is allways learning ,allways listening,and rarely will leave you feeling as if you were dictated to[especially if you were!-You know I'm just kidding about the benevolent dictator deal ,right?].
