It is important that a single fault does not inconvenience or cause increased danger for others, e.g. lights going out if fault on a socket. Therefore, the use of more than one RCD is required. Different types and sizes of property, will require different design considerations, and different equipment can enable some circuits to be grouped together on one RCD. Whereas other circuits may require a dedicated supply, e.g. smoke alarms and warden call. British Standard and IEE Regulations are subject to change, please always refer to the latest standards for all types of electrical design and installation work. BG offers a variety of circuit protection solutions, that will help the designer and installer to comply and meet these new regulations. The following areas require additional protection by an RCD not exceeding 30mA:i) - Socket Outlets (section 411.3.3) All sockets up to 20A. All mobile equipment up to 32A, used outdoors. Exceptions are socket outlets under supervision of someone skilled/instructing, and labelled socket, e.g. ‘Freezer’. ii) Cables buried in walls (section 522) - All cables concealed in a wall/partition less than 50mm depth, and without earthed mechanical protection, e.g. earthed metal conduit. iii) Location containing a bath or a shower ( section 701.411.3.3) - All circuits within these locations must have additional protection by an RCD. iv) Installations to be divided (section 314) - All circuits of an installation should not be connected to a single RCD. This avoids hazards and minimises inconvenience to others by reducing unwanted tripping. 04 Circuit Protection BG Consumer Unit Options Possible consumer unit options to support 17th Edition Wiring Regulations compliance.
