Running Wire Through Metal Siding

Metal naturally conducts electricity so to safely run wires through a metal building you have to protect the wires from wear.

Running wire through metal siding.

Step 1 drill a hole through your structure where you will supply your power. Running wires inside rigid metal conduit rmc is a little more expensive than burying underground feeder cable uf but it saves labor. A loop provides extra length for minor repairs or rerouting later. Fasten the cable with clamps.

This is because the top edge of rmc has to be only six inches below the surface of the ground while uf must be buried 12 inches deep deeper in some situations. Remove the sheathing and strip 1 2 inch of insulation from the end of the black wire and white wire. Do this by running them through metal conduits. Rewiring a house from the outside using conduit.

With an enormous amount of pvc sizes and fittings you can run electrical wire outside and up a tree should you choose to. Using metal conduit means less digging. To prevent electrical shock properly grounding your electrical system is important especially in a metal building. The national electrical code which is the basis for all local building codes has specific regulations for installing electrical wires so that they are protected from damage.

There are two ways to run electrical wiring on the exterior walls of a house or other structure. Using these separate 6 inch wires attach the bare copper wire to the green screw on the bottom of the outlet. Old wiring can present a fire hazard but is extremely expensive and complicated to replace. Use cable clamps to hold wire.

Rather than tear out walls or spend weeks fishing. It also forces water to drip off the cable rather than follow the cable into the wall. The metal siding has a electrical conduit penetrating the tin vinyl board and batten siding on the east west north south wall exposure yada yada the main conductors are insulated so we see no concern. Use wire stripped to strip 1 2 inch of insulation from each individual wire.

A favorite target of electrical inspectors is the improper use of non metallic cable nm in exposed locations such as basement foundation walls or along the face of studs and joists in unfinished framed spaces. A bushing seals around the cable and protects it from the sharp edges of the siding. One method is to run individual wires.
