installing larger electrical box

I decided to replace the 250V 30A receptacle in my older home. Once I removed it I noticed it is stuffed into a shallow one gang electrical box. That's a big receptacle in a box barely big enough to hold it, even without the 10ga wires. So I also want to replace the one gang box with a two gang one.

Seems like all the two gang boxes are made with the assumption that any switches/plug will be installed side by side. That is, they have two pairs of mounting tabs for installed devices, one to the left side and one to the right side of the box. I want to mount my receptacle in the center of the box. (I already have a 4x4inch box cover with the correct circular opening in the center) Is there any way of mounting my receptacle in the center of a 2 gang box, perhaps via some extra brackets? Or do I just have to mount it off center and then use a pair of 2x4inch box covers?

I think this is basically a cosmetic issue, unless there is something in the code I'm missing.

A flush mount device has mounting holes that match the 2 gang box mounting holes.

I think you are looking at a mud ring on your 4x4.
Is this it?

If that is the case, remove it and install your raised cover on the box.
Is this the cover you have for your receptacle?

Cool

Yes, that's basically it. You can't beat knowing the correct terminology! Once I searched online for "mud ring" I quickly found what I was looking for, something like this.

Thank's for your help.

That mud ring shown is for a lighting fixture, not an appliance receptacle.

Could you please post a picture of what your box currently looks like, and what you plan to install?
When you say "shallow" I envision a 4x4 box.
But when you say "one and two gang", I'm now thinking 1104 boxes.
