Socket Ring Main Mcb

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.

Socket ring main mcb.

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. 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. They are generally wired with 2 5 mm cable and protected by a 30a fuse an older.

Is this now a problem with the wiring. Ring circuits are widely used to supply sockets for 13a plugs. I have unplugged everything and it still tripped the rcd. 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.

He has checked my load current and says it is 16a. Changing the mcb didn t make any difference. Therefore the most you can take from any one socket is limited to 13 amps 3000 watts the mcb protects the cable against overload. Hi i have a ring mains for my downstairs sockets and very recently the circuit keeps tripping the rcd protecting it.

The main purpose of a spur is adding an extra socket on to an existing ring main circuit. Its simplicity makes it a great arrangement for that use. The ring is fed from a fuse or circuit breaker in the consumer unit. The other ring main is for tv stereo table lamps etc.

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. 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. Is this correct should i have the mcb changed to a 20a breaker.

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.
