Rule always said: "358.12 Uses Not Permitted. EMT shall not be used under the following conditions: (1) Where, during installation or afterward, it will be subject to severe physical damage."
Joe We have been mulling that over here for a while, and come up with the AHJ decision as well - but that doesn't bode well for some guys who have to deal with the ' ' inspector type.
AS an inspector....I honestly could not differentiate "severe" and "regular" physical damage.
Is 'severe' damage the EMT being flattened to 1/8" thickness? Damage is damage I would have to say. Determining future possibilities for damage has to be a basic common sense move on the EC's part.
