Recently bought a single story house that was built in 1925, it has a basement and an attic space. I've doing some updates in it, and have noticed some confusing things with the electrical wiring. There is a fuse box in the basement, but only has metal conduit coming out of it and going to the rest of the basement and I think most?! of the main floor.
I've been doing some work in my attic space, and the lightbulb that is wired up there is wired with functioning knob and tube, and there is old k&t all throughout the ceiling joists and attic walls, running to where the outlets and switches are on the main floor.
I am not an electrician, and have a few questions:
- Would an electrician only update a portion of k&t to modern conduit wiring and leave some functioning k&t behind??
- If so, how can k&t be wired into a system of conduit/modern wiring? Has anyone seen that done before?
- If updates were made to at least a portion of electrical, would there still be k&t throughout the attic or would that have been ripped out? How do I test if the existing k&t is functioning?
- How important is it to update a fuse box?
It's a confusing problem - thanks for the help in advance!
