A shroud provides protection against an unwantedtouch. to a conductor. The shroud is e.g. designed for solid part protection against fingers or similar objects larger than 12.5 mm, as described in the ingress protection standard 22X (ID is the abbreviation for ingress The LP2X requirement is a widely accepted requirement in electrical panels. The shroud can be designed to a higher or lower ingress protection rating. The shroud can be applied to a switching device or other products. The shroud is appropriate for a wide range cif devices, wherever a cable or a busbar goes into the device. The switching device is realized e.g. as electromechanical switching device, circuit breaker or switch, e.g. for conducting and switching DC or AC currents.

Conductors such as cables have to be fixed to the switching device in a switchboard or another arrangement. Present shrouds require modification prior to fitting to ensure they provide a protection according 1P2X when fitted. This means cutting or snapping of the shroud to the shame of the cable, This procedure is time consuming and often difficult to do accurately.
