Electrical and networks: prepare a technical schedule

Wires and cables, wiring accessories, protection devices, motor controls and network equipment are defined by their specifications and function in the installation. Group schedule references while distinguishing power, control and connection requirements. A replacement needs the full reference; for a new project, diagrams and network specifications help compare the requested supply with the products offered.

Information to include

• State the required voltage, frequency, phases and current. For cables, add conductor material, cross-section, conductor count, length and installation method.
• Include full references and diagrams for protection, motor control or network equipment. Request documentation for the proposed reference before accepting an equivalent.
• Break down quantities and lengths by reference, then state packaging, destination and required date. Connection accessories should be listed separately in the enquiry.
