When Mechanical Inspectors and Electrical Inspectors Need to Talk

[jar546]

There are many instances where it either pays to be a multi-discipline inspector (I am but no longer believe it that) or when the inspectors and plan reviewers need to talk. Here is one such example:

In a major repair garage, the pit is often a troublesome spot. NEC 511.3(C)(3) allows the pit area's classification to be either Class 1, Division 1 or Class 1, Division 2 based on whether or not ventilation is provided, specifically 4 air exchanges per hour. (it used to be 4 exchanges)

The electrical inspector is often told one thing but unless it can be verified by the mechanical inspector, all is lost. I have witnessed similar situations in other overlap disciplines.

Thoughts?

I believe in multi discipline inspectors. Both of my electrical inspectors are only just that electrical inspectors.
So in that case we talk all the time. Have not had a pit situations in quite a long time, but there are many other areas that are of concern.

That ventilation should be addressed on plan review....No?
