Mepd2o Engineers Radial Circuit Wiring For Electrical
Electrical radial circuit diagram. However when the circuit reaches the last socket the cable ends whereas a ring main travels back to the consumer unit. With radial circuits the cable comes from the consumer unit and travels to each socket simlar to the ring circuit. As with ring circuits there is no limit as to the amount of sockets that can be fitted to a radial. As described above a radial circuit starts at the consumer unit connects to each socket outlet in turn and ends at the final socket outlet. The other type of circuit used to power your home is a radial circuit. They are not so common in the uk but are used extensively abroad as the ring main or final ring circuit does have its drawbacks.
Radial circuits can therefore only serve a smaller area. Electrical radial circuit wiring including the size of cable and mcb that should be used. There are two types of radial circuit used for sockets type a2 which uses 4mm² csa twin earth fused at 30a or 32a covering a floor area of 75m² and type a3 which uses 25mm² csa twin earth fused at 20a covering a floor area of 50m². All of the socket outlets except the final one will have two cables one coming in from the previous socket or consumer unit and another going out to the next socket. Wiring a radial circuit in this diy guide you will learn how to wire up a standard radial circuit and also ensure that it is safe by using the correct size of cable and also the correct mcb in the consumer unit.
