Sizing and protection of conductors
The cross-sectional areas of conductors are determined by the general method described in Sub-clause 2 of this Chapter. Apart from
The adiabatic equation is a fundamental calculation method specified in BS 7671 (UK Wiring Regulations) for determining the minimum cross-sectional area of circuit protective conductors (CPC) and earthing conductors. Apart from this method some national standards may prescribe a minimum cross-sectional area. Selection of cross-sectional-areas of cables is certainly one of the most important tasks of the design process of an electrical installation as this greatly influences: This chapters details the different steps and methodologies for conductor sizing. 4 G7 G7 G16 G18 2 3 4 Methodology and definition Overcurrent protection. This method determines CPC size based on the relationship to the ...
