Third-Party Electrical Testing — What Inspectors Should Know   by Jim White and Ron Widup  The relationship between existing national and consensus standards, technical certifications, field acceptance testing, and determination of serviceability of newly installed electrical eqiupment is a critical one. Field Evaluation of Uncertified or Modified Products   by Chuck Mello  There are cases where an AHJ will come across electrical products, industrial machinery, or other equipment that does not ear the mark of a recognized testing laboratory.

What Goes into a Listing and Why It Is Important   by Thomas Lichtenstein  Products listed by a third party testing laboratory provide one of the cornerstones of the U.S. safety system providing protection from electric shock, fire and personal injury to the general public and workers.

Perspectives on PV: Questions from the AHJ — To Fuse or Not to Fuse by John Wiles Most utility-interactive PV systems with only one or two strings of PV modules will not require OCPD in the dc wiring between the PV array and the inverter.
