	The ~~actual~~ proposed location of rigid conduit or cable-conduit is approximated on the plans. Straight-line schematic diagrams are not acceptable. Quantities of cable or cable-conduit can be taken off by scaling. Cable-conduit is normally used for underground circuits not under pavement or shoulders or in concrete barrier or structures. Where the cable-conduit is located under paved areas and shoulders (including all shoulder types) it is encased in rigid conduit. Where the entire system or circuit is in rigid conduit, cable-conduit is not used. In this case, two single conductor cables plus a bare neutral (ground) of the required size are used for each circuit. Possible combinations of cables in cable-conduit are shown in Table 901.10.3.1.
