30 amp vs 50 amp outlet dimensions?

I replaced a 30 amp outlet with a 50 and used the same box and piping.(I did pull new larger wiring.The 50 amp receptecle I got was slightly larger than the 30 amp.5 minutes of filing and I am good to go.

Both are 3 1/8" diameter. Just checked both of mine.

I bought a 50amp RV box at Home Depot, due to the fact that is all they had. I went to my local Granite City Electric (Proud sponsor of the Boston Red Sox!), and got a TT30 receptacle. The hole size was the same, but the 2 had different mounting holes. I just drilled 2 new mounting holes, and now I have a TT30 with a 50 amp sitting on the shelf if I ever get a bigger camper.

woops, misread the question

They sure look like they are:

I,m a retired electrician.I know the wiring requirements.I just want to know if the physical size(dia.) is the same.

An odd question. Why do you ask? If you are considering converting one to the other, there's a lot more to it than the diameter of the receptacle. They are wired differently, you know.
