I am running a 120v receptacle and going to floor flange mount the box, in is next to a air tank for condensate drain, and I want to put another support on it. Does it say anywhere how a support must be mounted ( a mini ). I know the picture has the wrong size mini need a 0, but can I use neo magnets to mount it? I cant drill or weld on tank. It takes allot of force to remove it.
well, you *could* tig weld a SS minnie on the tank,
and then have the tank re certified.... ;-)
in food packing, putting a SS minnie on a piece of 1/2"
bare rod as a standoff is done all the time.. it's usually
a lot faster to run pipe if you can put the supports where
you want to.... but that is welding SS on SS, and not a
pressure vessel.
what i've done is put a 4 bolt strut flange on the floor,
and put a piece of 1 5/8" strut (unpunched) up, and
run the conductors inside the strut and punch out
with a sealtight, or switch, or limit switch, or whatever,
and then cover the strut with the snap on cover that makes
it into a listed raceway.
but it's prohibitively expensive to do it that way in food packing.
SS strut is 'spensive. and not listed for washdown areas anyway.
