My uncle has a log cabin that he gave to me and it was built back in the 40's. Since he's was an industrial electrician he redid the electrical in 1990 because of few plugs and knob and tube wiring. In order to avoid so many wires running along the wall he decided to drill through the floor and run the wire under the cabin to the next plug, switch, or if its a home run line. I looked under the cabin just recently and he just ran the romex loosely and it's laying on the ground. It doesn't look deteriorated or chewed. Some circuits close to the panel he just stapled the cable real nice and neat along the wall or ceiling. All junctions have covers and romex clamps on all boxes. All cables are stapled within 6" of fixture and stapled every 12". Also he put in some outdoor lighting on the porch and he just drilled through the logs from the inside and just ran romex out to the light. Is this acceptable by code? My uncle is not around anymore so I can't ask him. Any info would be appreciated.
