Thereare many cases where it is im-possible to install a conduitsystem. In such cases, prob-bably the next best results maybe obtained by the use of steelarmored cable. The rules gov-erning the installation of armored cable are given in the NationalElectric Code, under Section 24-A, and Section 48; also in 24-S. Thiscable is shown in Fig. 8. Steel armored cable is made by winding formed steel strips overthe insulated conductors. The steel strips are similar to those used. Fig. 4.

Care is taken in forming the cable, to avoidcrushing or abraiding the insulation on the conductors as the steel
