The 17th Edition Use of RCD's Explained It's important to understand that the 17th Edition differentiates between installations depending on the user.
E.g. the regulations talk of "installations not under the supervision of skilled or instructed persons" and "socket outlets for general use by ordinary persons" This type of installation requires "Additional Protection" by use of 30mA RCDs on many circuits that have not previously needed protection by RCDs.
Considering most domestic installations have a few socket circuits, a few lighting circuits a couple of bathroom circuits amongst others and, if all of these have been wired in the traditional manner, with twin & earth cable beneath the plaster surface, its difficult to come to any other conclusion than every circuit requires 30mA protection as well as protection by MCBs.
However, it's important to ensure that a single fault does not cause inconvenience, danger or other hazards therefore more than one 30mA RCD will be required.
For example a fault on the shower should not plunge the bathroom into darkness at the same time.
There are many types of property to consider from bed-sits to multi storey town houses. Dwellings with one bathroom to larger properties with two bathrooms and en- suites. Each will require its own design considerations.
There are many types of equipment to consider too. Some that can be grouped together onto one RCD like in a split load board but, there are other items of equipment that may require a dedicated supply such as smoke alarms, burglar alarms, warden call, door entry etc.
Alp Electric Limited can supply a variety of consumer units and devices that will help the designer and installer to meet these new regulations.
