Consultant trying to site me for not having a formal maintenance schedule for our grounding system (internal audit). Here's exactly what he states. I cannot find anywhere that requires this. Industrial facility mostly 480Y installation. Officially stating it comes from 1901.304 (g)
Here is the quote
Essentially OSHA took a circuitous route to get to this requirement:
? First OSHA required either GFCI or assured grounding on construction sites for temporary wiring per 29 CFR Part 1926.
? Then the Industry standard in 1910.304 (b) required a similar program for similar wiring in industry in "construction like" settings. Unfortunately while many industries are past the point of being able to, by regulation, use temporary wiring, in fact temporary wiring is still used in many plants (and not for construction only). Thus the extension of 1910.304 (b) to any temporary type wiring (flexible cord/cables) - even those used past six months and not technically temporary at all.
? Then 1910.304 (g) required that all building wiring (system, circuits, equipment) be grounded. Various means are provided in this regulation and NEC to assure that this grounding is in fact functional over time. Consequently the phrase "assured grounding" is meant to relate that a facility must prove that grounding in fact is functional; keeping in mind that various grounding schemes are available for use and may, therefore, need various "proving" requirements.
OSHA in general practice ALWAYS puts the responsibility on the user of equipment to determine either through manufacturer's information or through user knowledge (testing, inspections) that equipment is being used as specified by whomever designed the equipment.
So essentially, you can call the inspections needed for other than temporary wiring something else - besides an "assured grounding program"; however the requirement is still in play - the facility must have a means to prove compliance and usually an overall assured grounding program (by any other name) is how that requirement is met.
