Frequently Asked Questions
What is an electrical design basis?
An electrical design basis is the foundation document that defines all design parameters, applicable standards, supply characteristics, and criteria for an electrical engineering project. It ensures all engineers work to the same assumptions and provides a reference for design reviews and audits.
What should an electrical design basis include?
Key sections include project information, applicable standards and codes (IEC/BS/NEC/local), supply characteristics (voltage, frequency, fault level, earthing system), voltage drop limits, cable selection criteria, protection philosophy, environmental conditions, motor starting criteria, power factor requirements, and design margins with future growth allowance.
Why is a design basis important for electrical projects?
The design basis prevents assumptions varying between engineers, ensures compliance with the correct standards and local regulations, documents client requirements, and provides an auditable record of design decisions. It should be agreed with the client before detailed design begins.
