Way insufficient, if you're talking about
"normal" NEMA 5-15R
or 5-20R receptacles.
I would tend to agree - not for density of outlets, but for the kinds of
outlets. Most larger machines generally have some sort of locking plugs
(L5s and L6s). So better include those. Of course we all know that REAL
machines don't plug in...
One nice way of doing things is to have the boxes tethered to armored
flexible conduit (not BX, but sort of a plastic coated Greenfield), so
the box can move to the machine, and not the other way around. It is
quite legal.
RCS/RI is installing dual voltage locking receptacles (L14-30Rs), so that
most machines can be plugged in anywhere. Damn expensive, though.
