Q: Can an electric box stick out the wall about half 0.4 inch?

One question would be if it will seal to keep water out. Is there some sort of gasket?

I've seen fixtures mounted where the entire box was outside the wall.

They probably were not outdoors.

I think the idea is that any sparks or fire that comes from the wires will be trapped in the box and not set fire to the house. If that is accounted for, I thought in or out was just a matter of appearance.

There is no gasket. The manufacturer advises using caulking/sealant.

My question is: What is the code? Can the box stick out of the wall a bit? One way or the other, I'll find a way to seal it.

Photos don't add much, no idea what those even are. I don't see a hole the size of an electrical round box. Why can't the box be flush? One of the old work boxes with swing out ears would work. AFAIK electrical code doesn't care about whether a box is flush or not, you can have boxes that are surface mount for that matter.

"AFAIK electrical code doesn't care about whether a box is flush or not, you can have boxes that are surface mount for that matter."

This answers my question!

Thanks

Just be sure to let your Electrical Inspector know that you got your advice from some unknown self-proclaimed expert on the internet ... .. he/she will be more lenient .. John T.

Isn't that what Clarence Thomas did about reporting gifts? Why should Artur have to meet a higher standard?

Michigan's dictator Governor Whitmer had the state under a covid lockdown while she accepted the use of some billionaire's private jet so she could vacation in the FREE state of Florida.

But that's ok because she's a WEF democrat.
