Why fit an RCD socket outlet when the circuit is protected?

Since the 2015 amendment to the 17^th Edition of the Wiring Regulations all socket outlets required RCD or RCBO protection so why are RCD sockets and connection units still popular? Infact there are now new versions to latest standards available in M2 White Moulded, Easy Seal and Omega Metalclad.

SRCDs are primarily intended to provide supplementary protection and whilst they are for use in circuits where the fault protection is already assured upstream they can offer vital additional protection against electrocution in key areas of your property or workplace.

Instances in factories and warehouses where surface cabling in steel conduits is used and therefore is an exception under the regulations, circuit RCD protection can be troublesome and a local outlet to particular equipment is acceptable and preferred.

Additionally:

They offer a local and more accessible position for resetting following a tripping event.
Can be used on old but still compliant circuits that have no RCD protection.
Give additional assurance as a local device should the details of the upstream protection be unfamiliar or unknown

These new versions are also compliant with the latest BS 7288:2016 standard and provide a red and green dual flag system to indicate power on/off. The 30mA devices are mechanically latched or passive which means there is no need to reset following a power outage. This can be particularly useful on items such as fridge/freezers or other pieces of equipment where continuity is important.

Socket outlet versions also contain double pole switches and all units fit 35mm deep wall boxes.

The availability in the three ranges reflect the most popular areas of use. M2 soft edge white moulded for the stylish interior application; surface metalclad for the workshop or warehouse and Easy Seal for outdoor weatherproof installations.

RCD protected socket outlets continue to be popular but it is advisable to have them to the latest standards and available in styles to accommodate installations in the home, the workplace or the great outdoors. Stay safe electrically with RCD sockets and spurs.
