Our current home (mid-50s ranch in the Midwest US -- my AHJ has adopted the 2011 NEC save for the AFCI requirements, btw) is in good shape, save for the electrical wiring, which is a major bodge job. Some of the previous owners (this house was an O/O that recently became a rental unit, we are the first tenants though) thought it was a good idea to replace all the outlets with grounded outlets without hooking up their grounds to anything, for starters. The original 1950s fuse box is still present (no pennies that I know of, but there may be some overfusing going on as there are 30A fuses on 120V circuits in the box, and there's also a decrepit Edison-base thermal breaker roaming around there), and worse yet, the A/C installer decided it was OK to stick a 40A double pole breaker in a standard square junction box without a cover plate -- heaven only knows how he tapped it out of the main panel!
Given that the ideal way to fix this situation likely involves rewiring (the house is wired with NM save for the garage and basement which have conduit, and the garbage disposal which is some type of AC or MC and also happens to be the one outlet that is properly earthed) the whole kit and kaboodle atop replacing the main panel (the location is too high up on the wall it's on to be Code compliant!), how can this job be staged so that we don't have to move out of the house while it's going on?
BTW: our W/H is gas and our furnace is gas with electric ignition, but the dryer and range are both electric. The NM is cloth-covered (appears to be original to the house), btw.
