Use wiring diagrams to assist in building or manufacturing the circuit or electronic device. They are also useful for making repairs. DIY enthusiasts use wiring diagrams but they are also common in home building and auto repair.
Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components. Pictorial diagrams are often photos with labels or highly-detailed drawings of the physical components.
The wiring diagram lets you define the different installation components and locations (cabinets, control panels, consoles, connection boxes, etc.) and gives you a synoptic, functional view of the installation. The terminal strips and cabling connections between locations can be defined at the beginning, during or at the end of the project design. The length of the pathways can also be defined by the user and thus serve as a default value, for all cables within the given pathway.
Modern non-metallic sheathed cables, such as (US and Canadian) Types NMB and NMC, consist of two to four wires covered with thermoplastic insulation, plus a bare wire for grounding (bonding), surrounded by a flexible plastic jacket. Some versions wrap the individual conductors in paper before the plastic jacket is applied.
