<p>PURPOSE:To provide the method capable of appropriately selecting an electric wire used for a multipoint circuit. CONSTITUTION:In the selection of the electric wire for the multipoint circuit by using a magnetic disk 1 in which a datalized electrical wiring diagram for load is recorded, a processor 2 holds the data of the kind of the electric wire, and the thickness of the electric wire as a database, calculates the voltage decrease of the electric wire arrayed at the multipoint circuit from the data including load currents and a wiring length taken out from an equipment block plan decides the thickness of the electric wire from the calculated voltage drop, and selects the kind of the electric wire corresponding to the decided thickness from the database. Thus, the processor 2 decides the kind of the electric wire used for the multipoint circuit with which an electrical load is connected.</p> |
