As John said, you could do it yourself but a 3/4" Uni-bit is a expensive
tool for a one-off. A hole-saw might work if you're careful.

I'd go to a electrical house and ask them directly. Apparently John already
researched that it's not readily available in a two-gang, but perhaps the
store or one of the electricians hanging around (go early in the morning and
they're there) will punch your blank for you. All good electricians are
going to have Greenlee knockout set around.

With the right tools.. it's about a 2 minute job and probably could be done
pretty cheap! If you're in central Indiana... let me know. I'll punch it for
you for free..

I am wiring a SPA and have a manufacturer supplied subpanel. The
contractor prewired my 230v connection to a flush, plastic, double gang
outlet box
with a plain metal cover on it. I need to run the wiring from the gang
box
to the subpanel using three quarter inch weatherproof plastic conduit. I
can't find an appropriate connection to attach the conduit to the face of
the gang box. I have some right angle and straight weatherproof fittings,
but I can't find an appropriate face plate to accept the fitting. I'm
thinking it would look like a plain faceplate with a three quarter inch
hole. What I have found is box covers that do not fit with half inch
holes
in them. Does what I am looking for exist? Am I thinking about the
connection correctly?
Thank you, Dan. Remove protection to reply.
