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.
Crabtree’s range of consumer units provides many options to installers as they strive to meet the new regulations.
