STEP 11: Install receptacles

Four types of receptacles are used on the bottom of the enclosure to attach our various cables:

The small silver temperature probe XLR receptacles are each held in place with two size 6-32 x 1/2" machine screws and 6-32 nuts.

Note: Depending on the style of the AC receptacles, you may find it difficult to tighten the screws that hold the wires in later steps. You may wish to hold off on installing the stove bolts/nuts and applying the silicone until after the AC receptacle wiring is done.

The larger white AC power receptacles are held in place with 3/16 x 1/2" stove bolts and nuts. The 240V receptacles use three bolts each and the pump receptacles use two bolts each.

After installing, apply a bead of all purpose kitchen/bath silicone sealant on the inside of the enclosure where the receptacles meet the enclosure.

The observant reader will note that we actually used NEMA L9-30 receptacles (rated 600 VAC instead of 250 VAC) as these higher voltage plugs were more readily available at the time we assembled our brewery. You may always use a plug or connector rated higher in voltage or current than required - just make sure that your plugs and receptacles match.
