Article 500,electrical hazardous classification II, division I3/19
Electrical inspector claims that a woodshop is Class II, Division I . This would potentially require all electrical conduit to be threaded, all boxes to be dustproof, and more...building is circa 1960.
I am interested if anyone has had this experience and any suggestions to help resolve this quandary.
technically the fine dust puts us in the category. Good housekeeping and good maintanence schedules prevents the hazards from becoming accidents. Unfortunately, lots of inspectors have only seen dirty unkept shops
Well, TEFC motors are required, so the argument makes sense.
In our last shop the inspector required us to use plastic conduit (which, presumably is dustproof, since it's glued) and totally enclosed light fixtures. Also, we had to build a dustproof box around our transformer (which was in the shop), which was vented outside for cooling purposes.
Our current shop has mostly metal conduit (not threaded) and open light fixtures.
My guess is that technically your inspector is right, but most are not so concerned as long as everything is done right and well maintained. We sweep down our walls and the top of all piping and fixtures yearly.
