except where the flexible conduit is fished and where sections less than 4
feet in length are used in concealed areas for lighting fixtures.
9.
For steel conduit installed underground, wrap the entire length with tape using
1/2-inch overlap. Use PVC-based pressure-sensitive all-weather tape, 20-mil
minimum thickness, as recommended by the manufacturer for corrosion
protection of underground conduits. Tape shall be Scotchwrap 51 or equal.
