When y'all are doing a job, let's say you are installing a GFCI receptacle in a bathroom where there is an existing non-GFCI duplex receptacle (by the sink), and the box is an older metallic one about 2x3 in., do you break out the old box and install a "old work" box 4x4 and use a single-gang mud ring?
Or, do you tape around the GFCI and try to cram the GFCI in the box that is barely larger than the GFCI itself?
Can't they make the GFCI's smaller yet?
