Following is an overall picture of my HLT and HLT switch box.

The box is large to accommodate another switch for my pump, and possibly electronics for temperature controllers or a drunk-o-meter. Who knows what I'll cram in there.

The switch is on the side, and it is a 30A toggle switch from McMaster Carr.

The next picture shows the inside of the HLT. I formed the coil by filling it with sand and bending it around a corny. The element burns 5500W of electricity, and it was purchasted at Lowes.

The element threads into a half coupling I bought from moving brews. Since I don't want to electrocute myself, I enclosed the back end of the element. The 2" x 4" SS nipple was purchased from McMaster Carr, and the 2" galvanized pipe cap was purchased at Lowes.

I cut the hole in the keg with a carbide grinding attachment on my dremel tool. This worked, but I burned up my dremel in the process.

The ground wire is attached to a #10 screw that was welded to the inside of the nipple, and the cable passes out through a watertight gland connector.

I drilled a 1/8" diameter hole in the bottom of the nipple in case the element seal leaks.

The guy who did the welding brazed the ends of my HLT coil into a 3/8" pipe nipple that was cut in half.

It was necessary to enlarge the ID of the cut ends of the nipple halves to accept the copper tubing.
