Congrats on the upgrade. There will be kinks you have to work out when you change up equipment or grow areas. Your expansion will continue with your success, its good to figure out electricity early.
If two rooms share a wall there is a chance you could have 2 circuits in the one room. If you are in a trailer try to grow in the farthest bedroom, it usually has its own circuit and shares a wall with a bathroom or bedroom that is on a different circuit. In my experience of hood living in Michigan, anyway.
