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."

I think where it might get hit with a snowplow would qualify.

Snowplows and forklifts.

Isn't the time aspect, "...during installation or afterward..." a more recent addition to the rule? Before—always was just implied, I suppose.

Well here is an example I think is understandable (atleast as much as we have per the NEC)



On the left I think we have "physical damage"
On the right we are probably looking at closer 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.

Very good Roger

Pierre

My guess is,it'd be a common-sense type of thing. If it's in an area with vehicle traffic,EMT's probably a bad idea.

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.

Joe; you picked a real good point!!
