PROBLEM TO BE SOLVED: To provide an electrical wiring method that is used for electrical wiring inside a building, simplifies field operation and has a high degree of freedom for expansion and modification. SOLUTION: An electrical wiring method is used for electrical wiring between electrical equipment in a building 1. First, a circuit box 21 with cables having prescheduled electrical circuits and preliminary circuits and cables 9 and 13 to electrical equipment (for example, an electric outlet 7 and a lamp 11) is prepared. The box 21 with cables is installed in the building 1, and cables from the box 21 are wired to the electric equipment. Then, the circuit box 21 with cables is connected to a distribution switchboard. In the expansion construction of a building, the circuit box 43 with a cable for an expansion construction is installed and the power line 19 is connected from the already installed circuit box 21 with cables. |
