Should cables be protected in walls?

Can Romex wire touch insulation?

What can I use if I don’t have fish tape?
A fish tape is a thin, flexible steel tape, typically 1/4 to 1/2-inch wide, that comes on a large reel, similar to a surveyor’s tape measure. Heavy gauge wire can be used to create a fish tape. Much of the wiring in new construction can be done without it, since the interior of walls and ceilings is still accessible.
Can you fish wire through insulated wall?
Many installers seem to have a real fear of insulated walls. Drilling up or down and fishing cable through insulated walls is an inconvenience, but nothing more. Sure, there are certain techniques you can’t use through insulation, but there are always work-arounds.
What is a fish tape tool?
Fish tape is a tool used by electricians primarily for pulling electrical or other wires through conduits. The fish tape itself is a long, stiff, flat steel wire. Available in 25-, 50-, 100-, and 200-foot lengths, the fish tape is rolled up and stored in a round, plastic casing.
Can you run Romex on top of ceiling joists?
There is nothing wrong with running your electric on top of joists but you really should try to do it in areas that aren’t going to be exposed to any foot traffic. If you need to go parallel then simply run them a few inches down on the side of a joist. As for boring holes.
Can you fish wire through foam insulation?
Yes, you can. RetroFoam insulation is both soft and pliable. Its composition makes it very easy to fish electrical wiring through the injection foam insulation. Let’s go more in-depth on how fishing wires through RetroFoam works.
Is great stuff safe around wires?

How deep should WIRE be buried?
Bury in the Ground: Dig 24 inches There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
Can insulation go over knob and tube?
The existing knob and tube wires could be covered with a box large enough to maintain three inches of air space around each conductor, and then insulation could be spread over that. This type of wiring system can be buried in insulation, and it does carry a grounding conductor for shock protection.
