I have an electrician friend who has told me this is not right and should be changed to 20a breaker.

Socket ring main mcb.

They are generally wired with 2 5 mm cable and protected by a 30a fuse an older. I have also changed the sockets for double pole ones and it still trips the rcd. The socket contacts and applience plugs and cables are protected by the 13a or less fuses in the plugs. Ring circuits are widely used to supply sockets for 13a plugs.

Ring circuits are commonly used in british wiring with socket outlets taking fused plugs to bs 1363 because the breaker rating is much higher than that of any. The other ring main is for tv stereo table lamps etc. Changing the mcb didn t make any difference. Presently one ring main has a fridge a socket currently used for a toaster and two room sockets which may get used for hoovers etc.

The main purpose of a spur is adding an extra socket on to an existing ring main circuit. Therefore the most you can take from any one socket is limited to 13 amps 3000 watts the mcb protects the cable against overload. The ring is fed from a fuse or circuit breaker in the consumer unit. Use a multi meter to test for a radial or ring main final ring circuit available from our online store here even though the sockets are connected to two cables or 2 5mm and supplied by a 32 amp fuse or mcb it cannot be guaranteed that it is a ring main or final circuit.

The 2 cable ends at the cu are connected together in all modern rings and supplied by one fuse or mcb. Hi guys i have a consumer unit with a 32a type b mcb on a ring main which as 2 5mm t e sheathed cable. The ring circuit cable starts at the consumer unit fusebox visits each socket in turn and then returns to the consumer unit. One radial is a feed for the garage 2 sockets and a two flouros.

Is this now a problem with the wiring. As you can see it eliminates the need to wire a socket all the way back to the a consumer unit but the nearest ring main socket is used instead. Is this correct should i have the mcb changed to a 20a breaker. The ring starts at the consumer unit also known as fuse box distribution board or breaker box visits each socket in turn and then returns to the consumer unit.

Its simplicity makes it a great arrangement for that use.
