For kitchen remodel/addition, I currently have exterior OSB, 1/2 or 5/8 thick. I have a few outdoor lights and electrical outlets that have been roughed in. I used a 1″ deep circular mud ring but it gives only 1/2″ or so of reveal. So, I haven’t spoken with a stucco contractor yet, but to match the rest of the house the stucco finish will be that salt and pepper kind (think that is what you call it). They will do normal process, paper, lathe, scratch/brown/finish coats. So, is having a mud ring that sticks only 1/2″ or so beyond the OSB ok or should I go with 1.25″ mudrings ? I’m not done with the electical so I can change out the current 1″ mud rings. I guess I could leave the 1″ and just use longer screws when the lighting fixtures and outlets are installed but wont the stucco go into the mud ring and look lousy ? Advice ?
thanks !

You'd better run that question by your stucco guy - at least in areas that get wet the detailing of the water barriers depends a great deal on being able to keep everything tightly sealed between flashing, that tyvek looking stuff, and caulking, especially around penetrations - I don't think having a thick layer of stucco over the top of your mud rings is ideal.
Stucco over block is 3/8"
Stucco over block is 3/8" thick give or take. I don't see a lot of stucco over wood here.
Stucco
Felt paper, wire lath, scratch and finish coat over a wood sheathing can be from 1/2" to 3/4" depending finish textures. Call your stucco sub and ask.
BTW caulking is not flashing. It is a maintenace item and should never be expected to do the job of flashing in keeping water out.
Deeper mud rings are called 'tile rings,' and I've seen them as deep as 2". More than that, and you need an extension ring for the box itself.
Make up for 'extra' mud ring depth by setting the box farther back in the wall.
