I want to run a cable from my main house (120V) to my outhouse which is 170’ away. In my outhouse, I need 10 separate 20A outlets, each on their own circuit with individual breakers (not daisy chained). What size/gauge would the main cable need to be to handle that kind of load? Thanks

Hi All. I'm making a PID controller with an SSR to monitor and control a 240V (4500W) boiler I've made. The boiler works fine standalone, but it needs some automation for my application. For PID + SSR design, I followed everything in [url=https://www.youtube.com/watch?v=uCx61lK7MdI]this video[/url] to a T, and then realized I made the amateur mistake of assuming the wiring setup from the video would work identically for 240V. The guy in this video is using 120V ... I can hook my 240V up like this, but one of the 120V legs will always remain hot :| How can I adjust this PID+SSR design to control switching off both hot legs with the PID? Someone on the YouTube comments mentioned using a "separate contactor to switch the 220, and a 24v transformer to power the contactor coil" but I was not able to gain confidence on how exactly to do that... Any help is much appreciated, as always!
