The development of software for selecting circuit protective conductor (CPC) for low voltage installation according to IEE standard / Mohd Syahrin Abd Razak

The manual calculation performed during designing a cable can be difficult and may create errors. This paper describes developed software to help the electrician to perform the calculation for selecting circuit protective conductor (increasingly called the cpc) in cable design process. The circuit protective conductor is a system of conductors joining together all exposed conductive parts and connecting them to the main earthing terminal. Strictly speaking, the term includes the earthing conductor as well as the equipotential bonding conductors. The developed software provides more accurate and faster results to the manual method. The software is developed using Visual Basic 6.0.
