NEC wet location.

I not sure you are correct (and I am open for correction). Drywall is not an acceptable protection material. So if it's drywall then it should be evaluated as if there is no drywall,

Where did the discussion of drywall come from? Are you reaching for justification of your position?

My point was, if the location is called wet then all of the electrical installed must be suitable for wet locations, the plan inspector cannot say the panel needs to be rainproof but the switch does not.

An argument was put fwd that a 1 and 3R flush finished with drywall has the same water protections. Not the case.
A 1 flush finished with maybe 1/2ply might have same front door protection as the 3R.
 
"is it a wet location?"

Answers range widely, right here on MH forum. Thank goodness I install RH meters on the walls. LOL. ;)
"It can't be wet if it is typically less than 95% relative humidity, and therefore, not a condensing environment, and not subject to rain."
 
The question was (from MH thread), in an outdoor kitchen that is exposed directly to the weather, is the underneath enclosure wet damp or dry?

Look in Article 100, under "Location, Damp" and
"Location, Wet". It sounds like the enclosed storage
area you're talking about falls under Damp. NM cable
isn't allowed in damp or wet locations, so don't think
it matters whether it's damp or wet.

What exactly makes the enclosed portion "damp"? Just because it has no controlled air? In my outdoor kitchen the underneath will temporarily get near 40%RH but never wet from rain, after that it's 20%RH or less. Seems like a dry location to me.

If controlled air is the requirement, then the NEC code should say so. Makes sense to me.

So maybe interpretation?

The point I made was: a closed Type 1 door would provide similar protection from  splashing as would a closed Type 3R door. Drywall or flush mounting was not part of my comment.

The bottom part, below energized parts, of a Type 3R enclosure is allowed to contain knockouts and openings the same as a Type 1. Also the definition of a Type 1 enclosure says it protects against indirect  splashing.

I get it, but who evaluates just the door part of an enclosure? Is that something I can argue with an inspector, "the doors are the same in this setup, so........". If it's a wet location and I install a 1 that is flush finished to 3/4ply (10ft of ply in all directions), I am good, using ply gets me around a 3R requirement?

No you argue that the listing of a Type 1 enclosure says it is protected against light splashing and the Listing for a type 3R is also only rated for light splashing due to the lower parts of the enclosure being similar in construction.

Also don't forget all of the other equipment and devices also need to conform to the location rating he wants for the panel.

Type 4 enclosures are what is needed it you want watertite.
