By "fuses" i meant "breakers" And i know i have to upgrade the wire guage. However i may not rewire what's already there, but instead add some additional dedicated circuits that are 20A. I know the rating of the box can be far less than the total of all breakers. Not everything is in use at once. I actually have the majority of my lights on a single 15A circuit which is fine since most of my bulbs are LED anyway. Waiting for the rest of the flourescents to burn out I'm also aware the outlets themselves need to be rated for 20A. They're like $3 at Home Depot But i've about hit the limit on what i can draw, and since i'm a cruncher, of course everything is always running when the oven is on, the dryer is on and the central air kicks on all the same time :/
