This project has to be well thought out , because case inside too narrow and components too big, then we have to apply carpenter's law measure twice, cut once.

Notice there's not too much space on the base plate and capacitors almost do not fit the next floor up._MG_2625.jpg

Thanks Bill, but to be 100 % sure, when you say red together and black together, is red-red wires together to hot and black-black wires together to cold-neutral part of the inlet power. thanks in advance.
