Step 1: Parts list
My parts were bought and scrounged from other things.
2x receptacle's. this is where the grade and quality comes in. I used hospital grade 20 amp plugs with integrated surge protection and GFI protection on the circuit as well. Scored from ebay for 19 bucks each.
Wire......again pick and chose, something good quality that's meant for use as a portable appliance cord. i used a cord from a 800watt stage spotlight, over kill but heat resistant and uses 12 gauge wire.
(make sure to save a few pieces for jumpers between your plugs, about 6 inches. )
Male Plug - I used a hospital grade 20 amp plug, found in my parts bin. Shop around, home depot would have a basic version of this. Ebay if you want a nice hospital or audio grade plug. Make sure you get one that has the ground plug on it.
Box - I used a dual gang outdoor box with a 3/4" non threaded fitting.
Through tight vapor fitting.....not essential but acts as strain relief. Will be found in the home depot isle close to the box. NOTE: you will also need glue to attach it, your supposed to use pvc glue, but being that its not going outside i just used gorilla glue and its never coming outa there so im not worried about it.
Cover pate.. plastic, metal, whatever you want, i used stainless steel, was the most expensive one there but it looks nice when its all done.
Tools, wire cutters, strippers, and a few screwdrivers.
