ECN Forum Forums Code Related Discussion NEC & other Code issues Commercial Range Hood - Residential Dwelling

I've been asked to install a commercial range hood in a fancy residential kitchen. The hood is in good used condition with luminaires identified for the application. It is wired so that the junction box is on the outside of the hood with EMT conduit penetrating the side and routed through the hood's ceiling to each fixture. Hi-temp conductors throughout etc. Referencing NEC 99 & 02 (my 05 code is in my shop, regardless, here in NYS we are still working under the 99 code) 410.4(C)(4) ..."wiring methods and materials supplying the luminare(s) fixtures shall not be exposed within the cooking hood" what would be your definiation to "exposed"? Also, does this code apply to a commercial hood installed in a single-family residential kitchen?

I'd rather not route the conduit on the exterior of the hood as it will be plainly visible.

Need some good argument here for the AHD.
