A couple of posts mention using spray foam inside raceways, is that stuff approved for use within electrical equipment?
Jay, as far as I'm aware, no, you are supposed to use proper caulking agents inside things like conduits, especially where the conduit could become a fire-path, spray-foam as a rule isn't self-extinguishing, in fact it burns quite readily.
Unfortunately, spray-foam has become the slap-happy approach, leave the spray foam to the DIYers that use it, get the proper stuff.
Scott35,
Is there any chance of you maybe making up a generic wiring schematic for the Tech Reference Area, with respect to basic Refrigeration installs?
At one time I used to be able to do these installs no worries at all, as the EC company I worked for about 10-odd years ago specialised in them, it's a funny thing, when you leave doing that sort of work, it's hard to remember just how it's all done.
If you need a hand doing this, flick me a PM, I can sort of remember what goes into a Reefer install.
