These enclosures are intended to be installed where unskilled persons have access. They are intended to be integrated with electrical equipment on-site by skilled persons (installers). They are intended to be installed where the prospective short circuit current does not exceed 10 kA unless they are protected by current limiting protective devices with a cut-off current not exceeding 17 kA.
An enclosure is an integral part of an electrical accessory and provides protection against external influences (e.g. mechanical impacts, ingress of solid objects or of water). BS EN 60670-24 provides its users with guidelines for the classification, marking, instructions for protection against electric shock, and provisions for earthing. Using BS EN 60670-24 guidelines improves safety and protection, and ensures protected electrical equipment.
