I am going to put in a new service at my house when the weather breaks going from 100amp to 200amp and sort out some of the ckts more, The wiring is ok i have been all over the attic this week since i am putting in a new bathroom and had to run all new wiring, but i do have alot of splices that are either in a box or not and most box don't have covers. When the weather breaks this will all change. Hell my tv shut off the other day and i found out that a receptacle in the living room is all so on the same line as the washer. that has since been changed since the washer is now in the bathroom. I have alot of stuff were they just spliced off of what ever was closest to them at the time over the years and iam going to change all that.
