RIGID-METAL-CONDUIT AND INTERMEDIATE-METAL-CONDUIT WIRING70. Rigid-metal-conduit wiring is allowed for both exposed and concealed work and for use in nearly all classes of buildings. For ordinary conditions, wiring in metal conduit is probably the best, although it is the most expensive. The advantages of metal conduit are that (1) wires can be inserted and removed, (2) it provides a good ground path, (3) it is strong enough mechanically so that nails cannot be driven through it and so that it is not readily deformed by blows or by wheelbarrows being run over it, and (4) it successfully resists the normal action of cement when embedded in the partitions or walls of concrete buildings.A recent innovation is intermediate …
