I intend to install a HPWC in my garage. My breaker box is on the side of the garage and I'll be installing the HPWC directly below it, a total run of 4-5ft.
I plan on using 4g for L1+L2, and 8g for the ground. My question is about running the wiring in the wall. If it is going straight down from the box and coming out of the wall below it into the HPWC do I need to run it in conduit or put a box in the wall where it exits? I assumed it would be a matter of running the three wires down, out a 1" hole in the wall into the back of the HPWC and nothing else. Is that correct? Thanks!
