So step one in our assembly is to cut up our project box basically I just turned upside down the plug outlet and then marked out a grid for spacing. For the 12” project box we are using 12 relays and 6 outlets fit the space perfectly. Take care when cutting the holes out with your dremal tool that you don’t cut at an angle or you will have some grinding to do.
Next step is to attach the outlets to the project box using some screws and nuts. Depending on the type of outlets you are using you may want to consider attaching the ground wire before screwing them into their final place. With the outlets installed I recommend at this point you fill the gaps around the plugs with some silicone or hot glue to help keep out the local environment.
This is a great shot of how to do the wiring in this setup. So as pointed out earlier we will be breaking the tab off between the hot side of the outlet while leaving the neutral side of the outlet enact. The reason for this is so you can jump between the outlets with a small amount of wire. Make sure to keep this wiring clean and low profile while you set it up.
So next up is to create the base plate for the relays to be mounted to. Using a sharpie place the acrylic on top of the box and trace out the inside of the box to be cut out. Leave a ½ inch gap between the backs of the outlets and the acrylic for the wires to fit.
