Thanks for the link, looking forward to discussion. Quick comment: Table 130.7(C)(15)(A)(a) looks interesting, but if I'm reading it right it cannot be used when using IEEE 1584 for hazard analysis. Is there any guidance for risk analysis in that case? Is the new risk assessment procedure in F.2 meant to be used? |

110.4 B(3)(a) Exception: says that a plugged in piece of equipment has no need for the plug to be inspected until it is relocated. Even though it is plugged for portability, a plugged piece of equipment may be plugged in and stay plugged in for many years. Plugs are not just for portability, but may also function as a way to de-energize the equipment for testing and repair. Corrosion can build up over time in the plug - receptacle connection. This creates heat and can cause melting and exposure of energized wiring to the operator or a short. An inspection for loose pins and discoloration of the plug when ever the equipment is tested or repaired is not an unusual requirement. UL allows equipment up to 50 Amps to be plugged. See NEMA 6-50, 10-50 and 15-50 plugs to see what i am talking about. Equipment that draws 50A is not likely to be considered to be "portable." Nor is it likely to relocated until it is removed from service permanently. |
