Wood Saw Mill

[Michael15956]

I'm preparing a bid for re-lamping of the old existing fixtures which are not dust tight in a wood saw mill. Is this considered a classified location and governed by Article 506? The existing fixtures are fastened in place by plug and cord in a 20Ft. ceiling.

TIA

506 is based on the European "zone" system and covers what Articles 502 and 503 cover as far as classified areas go. The saw mill would most likely be a 503 application and not a 502 application. 503.130 does not require dust tight fixtures.

Thanks Don, 503.10(A)(2) does require boxes and fitting to be dusttight though.
