i would prefer your personal explanation rather than code text.

312.2 Damp and Wet Locations. In damp or wet locations, surface-type enclosures within the scope of this article shall be placed or equipped so as to prevent moisture or water from entering and accumulating within the cabinet or cutout box, and shall be mounted so there is at least 6- mm (o-in.) airspace between the enclosure and the wall or other supporting surface. Enclosures installed in wet locations shall be weatherproof. For enclosures in wet locations, raceways or cables entering above the level of uninsulated live parts shall use fittings listed for wet locations.

R703.1 General. Exterior walls shall provide the building with a weather-resistant exterior wall envelope.

The cabinet can't be sealed to the wall. Water will get behind the cabinet and enter the wall cavity as well as the cabinet. Conductors are spliced without benefit of a junction box. Some would say that punching holes here and there violates the cabinet listing.

The claim was made that there are no splices in the wall.

I understand the part anout no splices in the wall. But if you install a panel over an old hole, and there are no penetrations in the cabinet at the hole ... ?

The hole is an opening in the exterior wall. The 1/4” gap between the cabinet and the wall will let water and bugs into the wall cavity.

Would you guys cite someone for vinyl siding tight around a meter can? Or just strictly the gap behind? Asking for a friend....
 
As you can see from the picture that panel has no flange for a waterproof mounting, as far as I recall I've never seen a panel with a flange for waterproofed mounting. About 15 years ago I remodeled a few homes I had built in the 70s, there was a common failure in all of them, all of the shower wall penetrations for valves were leaking, nobody makes a shower valve with a flange for a waterproof installation (like a shower drain). I went so far as to call Moen and Delta but they wouldn't talk to me about the problem, they had their code approval so they didn't care whether they leaked or not, especially 30 years later.

Years ago I was talking to a construction defects attorney and asked him about having a building inspector testify about something, his response was that building inspectors never deal with the important stuff (this is the guy who got $19 million for leaking windows set in sealant per mafs specifications so to code), I think the problem here is Tiger is beginning to confuse building well and building to code, two entirely different things, maybe we all ought to all kick in some money and stage an intervention for him.

I would like to know the proper way too. We have very few stucco walls here, almost all are vinyl siding.The electrician always mounts the meter panel over a piece of house rap before the siding crew comes in.
 
Is a patio "slab" a foundation?

IMO...If you build walls on it....yes. Everything gets built on a "foundation", it is just usually frost protection that is in debate...

R401.2 Requirements. Foundation construction shall be
capable of accommodating all loads in accordance with Section
R301 and of transmitting the resulting loads to the supporting
soil.
Fill soils that support footings and foundations
shall be designed, installed and tested in accordance with
accepted engineering practice. Gravel fill used as footings for
wood and precast concrete foundations shall comply with
Section R403.

So you are okay with any rain, snow, moisture getting directly in the wall?

I'm in the dessert and we don't allow it. Stucco, vinyl, brick, etc. As stated earlier, most exterior boxes are not listed to be in stucco,brick, etc. Here we have the install WRB then cement board and mount the box to that and stucco to the cement board. If vinyl, usually installed on top of uni-strut after vinyl. Same with brick, box installed after brick. These areas are usually done first so the box can be set to get rough-in.

Siding does not protect against rain, snow, or moisture. That is the weather resistant barrier's job. Siding's job is to protect the weather resistant barrier and to look pretty. In high moisture areas, like where I am, we even add a secondary plane of protection to fight capillary action.

I agree. The areas between the meters and panels is not protected if not installed first. Here that means the sun will destroy the WRB in a very short amount of time and then you will have a direct opening in the WRB to the wall behind it. We don't get much rain but when we do it is in large amount at once. 6" in 2 days last week.

Very true. The degradation is usually related to UV damage, so here int he Great White North, we can wait around for that kind of thing.
 
This solar array will produce at peak performance for about an hour each day. A major PV company did this. They also installed a 200 amp electric service and have stood me up three times in a row.

Dont know what the orientation is, but it looks like the roof on the left could support some panels. At the time the picture was taken, they would be replacing the ones on the right that are shaded.
 
EMT is permitted to be used as an equivalent to an equipment grounding conductor. I have a poor opinion of that practice. Here we see the lock ring at a sub-panel. I can see approximately eight of eighty feet of EMT. The contractor is serious about his reluctance to provide a wire for the EGC.

The feeder involved shall be #2 awg. The contractor points to the -2 after THWN as proof that this is in fact #2. Even if the lock ring was tight I am pretty sure that I wouldn't approve the EMT as a grounding path. Well in fairness I should point out that there were a bunch more mistakes made.

He acted surprised when I asked for the dead front to be removed from a sub-panel. The job is a service panel upgrade ........which had him wondering why I want to see inside..... he pointed out that there are no breakers in the sub-panel...."What are you looking for?" Once the dead front was removed I said, "That, I was looking for that."

A major HVAC contractor that can't hire competent help or supervise the help they have. The picture is taken from the attic access.

I can count on them to never have a sloped condensate drain.

The job is a service upgrade. The person that met me was quick to point out that he drove 75 miles to be there. When they tell me that up front it is taken as a plea to go easy on them.....you know.....no minor corrections. I always take that into consideration and if there's a minor correction I might allow a picture of the correction completed to final the permit. However, more often that not I find major and minor corrections.

The existing ground rod was reused.

There's more that they don't get about grounding.
