Ring main cable size uk. Cable selection copper only up to 25mm above this cable reactance must be considered. Other factors must be considered grouping fixing pass through insulation. The ring circuit is still the most common mains wiring configuration in the uk although both 20 a and 30 a radial circuits are also permitted by the wiring regulations with a recommendation based on the floor area served 20 a for area up to 25 m 2 30 a for up to 100 m 2. The length of cable used in a ring circuit is limited to 50 metres for circuits protected by an mcb.

The floor area a ring main serves is also governed. In most domestic situations the cable size used for sockets on a ring main or radial main is 2 5mm twin and earth cable. 2 5mm electrical cable with neutral wire live wire and bare earth wire. Ring mains as they are called are a series of cables linked together starting and terminating at the same point in a distribution board.

The main purpose of a spur is adding an extra socket on to an existing ring main circuit. The cable size is important it has to be either 2 5sq mm or 4 0sq mm twin core and earth these are rated in free air at 24amps or 32amps respectively. Its simplicity makes it a great arrangement for that use. Floor area for a ring main or final ring circuit.

Enter your proposed cable size type of insulation voltage ambient temp 30 is norm your cable length and circuit load in amps. The maximum area for a ring main is 100 square meters. 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. Not suitable for ring mains.

Sizes of 1 or 1 5 mm 2 are typically used for 6 or 10 ampere lighting circuits and 2 5 mm 2 for 20 ampere radial or 32 ampere ring socket circuits. With each socket outlet is normally rated at 13 amps as a rule of thumb they are limited to under twenty outlets it is unlikely that the variety of domestic appliances being used at any one time will exceed 30amps. Standard sizes have a conductor cross sectional area of 1 1 5 2 5 4 6 and 10 mm 2.
