Question about electrical box inside project RV
Hello, I have recently purchased a fixer-upper motorhome (major project, basically torn apart inside, had to rebuild everything) and am nearing completion on the electrical stage. It came with a power distribution box with breakers and fuses. Both the 12VDC and 120VAC circuits connect here. I am just wondering... what is the giant transformer for? It's on the bottom in the attached picture. Also there are what look like resistors near it. Can someone explain if this is for the 120v system and how it affects it? Thanks in advance.
