I am in the process of replacing the "safer mistakes" in my turn of the century Victorian. The poor old girl came to my care with Federal Pacific boxes in the house and garage and a hodgepodge of modern romex, cloth wrapped romex(without ground of course) and a little bit of knob and tube remaining per my electrician.
The pro has already handled replacing my main breaker box and my service and will handle the knob and tube in time, but I am tackling the new stupid maneuvers made during bad remodeling work in the last 30 years or so.
First to be tackled is four new circuits where I think/know there should be dedicated circuits.
2) dishwasher and disposal(I know they are supposed to have their own circuits, but I might just run 10-2 on a 30amp breaker to save the open spaces in my box
3) & 4) front porch and back deck, which will have fans and Christmas lights run from them as well as the electric lawnmower/string trimmer/leaf blower
Fortunately all of these locations are on the first floor, and since I live in a pier and beam house, I can reach any of these through the floor with a drill and some careful planning.
What I am not positive is how to run my wiring under the house. I believe the electrical code says exposed romex is allowed in uninhabited spaces, and the only things that inhabit my crawl space are weeds and those giant frightening cockroaches that like to populate Houston. The question is, am I pushing my luck if I just run exposed romex stapled under my joists, the farthest distance being to my front porch which I think is about 75 ft?
Am I better off running my line inside of that lovely grey pvc and strapping that to my joists(while I'm at it strapping my hodgepodge of plumbing lines in more locations, the prior plumbing is just as bad as the electrical)?
My concerns are not making the inspector flip out and make me do more work when I sell the place as well as not doing anything that will make the place burn to the ground.
