Inspector's Tips

Oct 1, 2005 12:00 PM, By Tom Garvey, electrical inspector for the state of Wisconsin

Follow these tips so your wirewayless wiring installation passes inspection.

1. Following the NEC guidelines, install electrical wiring and equipment in a neat and workmanship-like manner.

2. Use control gear listed to UL 508, as they meet the regulations spelled out in NFPA 70 and NFPA 79, respectively.

3. Have documentation to show your machine was built and tested for its particular environment.

4. Ensure the conductors and cords are electrically protected within their limitations, voltage, and currents.

5. If using transient voltage surge suppressors, install them downstream from the circuit breakers or fuses so they don't become a fire hazard.

6. Do not use supplemental protectors as a substitute for a branch-circuit-rated overcurrent protective device.
