I agree with Bob. An engineer may be able to cite some obscure data and calculations that say the raceway can sustain the likely physical threat but whether it is "exposed" to that threat is going to be the AHJs call.

The code is complicated enough, we don't need to legislate common sense. These things do seem to be a local decision though. As long as everyone locally is on the same page it is fair. The confusion starts when 2 inspectors, working for the same AHJ, don't agree. Then you are timing your inspections based on the inspector's days off [Linked Image]
