Sample questions
01What is the minimum copper cable cross-sectional area typically used for a 32A EV charging point on a domestic radial circuit?
- A2.5mm²
- B4mm²
- C10mm²
- D6mm²
Why: 6mm² copper is typically selected for a 32A EV charge point so the current-carrying capacity and voltage drop requirements of BS 7671 are met for the installation method and route length.
02What is a commonly specified minimum IP rating for outdoor wall-mounted EV charging equipment?
- AIP67
- BIP54
- CIP44
- DIP65
Why: IP54 is a common minimum for outdoor EV charging enclosures, giving protection against dust and splashing water; many units exceed this.
03Which cable type is most suitable for a buried supply to an EV charging installation?
- AFP200
- BPVC/PVC twin and earth
- CMICC
- DSWA
Why: Steel Wire Armoured (SWA) cable provides the mechanical protection needed for direct burial and outdoor supply runs to charge points.
