I just looked at the door and the handle for sure isn't made for outdoor.
All of the buttons are typical Allen Bradley but no rubber over the push buttons.

You can order NEMA-4 buttons with or without boots.

I think (emphasis on think) the boots are recommended if there are going to be icy conditions, among maybe other things.

No that you mentioned that. I had a recent inspection where we relocated a control station and it was moved closer to an outside area.
We opened the control station box and looked at the back ot the buttons and it seemed to me like they were oil-tite and he accepted that as OK for outdoor.

BTW, no ice to be concerned with here.

You can get boots for 30.5MM (full size) A/B buttons, they just screw on in place of the locknuts.

Hmmm...
Why is it that EVERY one of your posts, no matter what the subject, or even the forum, has a link to the same vendor website, and you have NEVER posted anything that doesn't involve a "question" about a product that they sell?

Hmmmm.... inquiring minds want to know....

Do you put initials inside every panel and box you install?

I would just install the right box to begin with. Red stickers suck.

Years ago, even venerable suppliers like Hoffman used to say you could add a "Drip Shield kit" to make a NEMA 12 into a NEMA 3R. There used to also be a difference in the enclosure painting spec in that Type 12 didn't require the salt spray test that is part of 3R, but enclosure painting technology has changed (epoxy powder coating on virtually everything now) to where that's no longer an issue.

What changed is that when UL took over doing the 3rd party testing of the old NEMA ratings, the test standard for 3R required two things that made this invalid now: The end user was responsible for mounting the drip shield and drilling the weep hole (3R requires that moisture will not accumulate inside to where it contacts live parts, so you need a drip hole to let it out, which would violate Type 12). UL never allows a rating of a product to be dependent upon the actions of the user. But if that's what you did, I don't see a need to turn yourself in, unless maybe you hid some body parts in the boxes.

We were going through the start up checklist for one of our lines and I noticed that one of the cabinets housing VFDs was a "Signature Series" with a little plaque with names on it from the supplier or contractor or whoever

Every piece of equipment I've started up or commissioned going back a long time I initialed and dated.

ie: MAC SU 28 Mar 0000

Take enough pride in your work to sign it.

Next time I'm down there I'll take a picture if I can, it was pretty elaborate. It reminded me of how you see consumer sports equipment branded and I had never seen or heard of that before
