Double gang Box

[mstrlucky74]

I get confused by the statement below. Is this a double gang

Wall outlet boxes shall be of size and type to suit each individual location. In general, doublegang
4 inch square boxes with plaster rings, 2-1/2 inches deep

If I understand your question,

4" square box is not a double gang box. It is a "4 inch square" box

You turn it into a single or double device box by the use of single or double device plaster ring.

Agreed. If you use a 2 gang ring then it is a 2 gang box. Why does this matter?

This is also a two gang box. So how do you differentiate when you see "provide 2 gang box". I guess in my original post it says 4" box 2 gang so that is clear.

It does not matter how you provide the 2 gang. If the plans call for a 2 gang then you need to know the limits of the space and what will wok with the number of conductors. The box you provided a link to can be a 2 gang but I would only use that if I had a fill issue with the number of conductors. Providing a 2 gang IMO only refers to the final outlet space. When a 2 gang is required it is generally to ensure that a specific switch or something similar would fit in it. For instance a 2000 watt dimmer may require a 2 gang box.

That box would be used when you need more cu in area, need to use a barrier or you like spending $45 for a two gang box. For a 2 gang I would use a 4 11/16" box with the appropriate depth 2 gang adapter cover.
