How do I safely and (pretty) cheaply implement this one-off home electrics / electronics project? I have a low-wattage controller that will drive a high-wattage load having to do with the heating of water. I already have a GFCI extension cord that will stand between EVERYTHING and the wall outlet. The main complicating factor is that this is a single, custom-built thing so I need to use off the shelf pieces for a housing, etc.

I need to power a PID controller that draws about 5W at 120V, which will power a 1500W water heater, via a solid-state relay, also at 120. I am certain I will be plugging into a 20+ amp circuit and as mentioned above the fold, everything involved will run through a ground fault interrupter. I have a circuit diagram. Basically I am trying to figure out the mundane stuff, like how to cheaply and safely mount the components (PID controller, SSR, socket, plug) and wire them together. Like, can I put some galvanized steel screws into a wood board as terminals and connect heavy gauge, insulated wires between the various terminals, then securely mount that board in a tupperware box? Is there such a thing as a breadboard that can take 20A that I should be using instead? Thanks for any advice.
(The ultimate goal is to set up a RIMS wort heater and circulator for home brewing, if that helps picture things.)
