mudd boxes

[wire monk]

Is it a violation to use a regular metal 4/0 box in brick and concrete.. I was always told you have to use mudd boxes..??

What would be the physical difference? They're both made from the same material so why would a mud box be better?

I do it all the time.

That seems like more of a spec driven rule someone got confused on.

I agree. I have used 4/0 boxes and 4 square boxes with plaster rings in masonary for years.
