I'm on with rewiring a front house in a back-to-back flying freehold property, where the top attic floor goes over the top of part of the house behind. I've got some floorboards up on the top floor, and the socket cables for this property runs alongside the lighting wiring for the house behind. I'm encountering more and more of the house behind's wiring. My concern is that in the future someone working in the house behind will come across the wiring I'm doing today and interfere with it or damage it. Are there any special measures to be taken in a case like this?
