Referencing the specification standard U.L. 2200, many times- local inspectors blur the line between its dominance for standby generator systems and NEC-70 (NEC- code). The former covers ‘factory’ design wiring on stationary standby generators subject to witness testing by a U.L. certified representative. The latter applies to ‘field wiring’- that is anything outside the box including connection conduits, load wiring ( at 75 deg. F) transfer switches, distribution panes and the like. As resident designer for the past twenty-six years, I have myself- written eight standards/code rebuttals successfully, both for U.L. and local inspectors.
