We recently purchased an older duplex that has been rented out for some time. The resident of one half moved out and we were starting the process of fixing it up to rent again, and decided to remove the ugly sheet flooring and replace it with something new.
Upon pulling it up we discovered massive water damage to the floor and sub-floor and consequently needed to remove the cabinets to be able to access all of the damaged sub-floor, and the leaking drain pipe in the wall.
So my Electrical questions:
These are probably questions I can/should ask of the electrical inspector and/or the electrician who will be doing the work, I just want to have some idea of the answers before I ask them so I know whether they are steering me wrong.
1) Given the amount of work that has been done to find and fix the leak and the damage from the leak, has this passed the point where everything electrical in the kitchen will need to be be brought up to current code?
2) If all of the kitchen wiring needs to be brought up to current code
which seems to say 7 circuits are required: 2 for countertop outlets, 1 for range, 1 for fridge, 1 for dishwasher, 1 for disposal, 1 for microwave. However given that the fuse box only has 10 total circuits (the range, the water heater, plus 8 edison-based fuses) adding even some of the additional circuits, would require a larger panel, (or perhaps an additional panel)
3) If a larger panel is installed does that mean that all circuits going into this panel need to be redone? Or can circuits not involved in the kitchen mess be connected to the new panel?
4) If a larger panel is installed, does that mean a larger service drop is required?
The wiring is almost all cloth-wrapped 2 conductor, with no ground.
There are already two sub-panels next to the the above mentioned fusebox, one has two fuses and a disconnect handle that seems top go to a 240v receptacle for a window air conditioner, the other sub panel I wasn't able to open.
Some of the wiring is routed through a nearly inaccessible attic space with a low ceiling, no floor and a web of various trusses, but most of the wiring is in the crawl space which is dark and dirty but more accessible than the attic, (especially now that parts of the sub-floor are removed.)
Thanks in advance for any help.
