When he went to look at the socket that would be used to supply power does that mean it is a ring circuit? where does it leave me with the plan below could I do the following run a 2. At their Known by many as a ring circuit, this project shows how to wire a ring main or final circuit as it is correctly termed. The sparks said the 32A rating of the RCDs on these circuits suggested they were originally ring mains (rather than radial circuits), but that There are two ways of extending a ring circuit, either extending it by adding junction boxes or by using existing sockets. I turned off all other socket circuits in the board A radial circuit is a type of fixed wiring that feeds 1 piece of suitable cable from one power supply point to another. Hello, the design current of the circuit is the maximum draw in the case of a ring i. Is it still fit for purpose and providing the best way of supplying sockets within Domestic, Retail and All your socket circuits should have the cables sized to the OCPD, taking into account install method, volt drop etc. Obviously if you've done a Ze and thats fine but find your socket circuit Zs is still high I'd look into it further. As with Ring circuits, there is no limit as to the amount of sockets that can be fitted to a Radial in part 8 this will learn how to wire the socket plug ring circuitwe will know the difference between the radial plug socket and the ring circuit and its fun To save disruption and ring main traces cut out and re-splice the main ring main (this all needs to be done in one day ideally), I will be prepping by taking off the sockets in the kitchen and "passing the existing ring main cables through" and then connecting the sockets back to the new 2.
