Step 6: Build a meter and light display
I used 3/4" x 5" pine for the top and bottom with holes drilled for a 1-1/2" PVC pipe. After installing and wiring the meters, switches and sockets, install the pipe. After the pipe is in place, the top piece of 1/4" plywood is installed. Drill a 1-3/8" hole in the bottom plywood and attach. This will hold the PVC pipe captive.
