Demand Switch NA 16-1P Standard

Demand Switch NA 16-1P Standard

A Demand Switch can be used to minimise the electric fields from circuits which are not actually supplying power. A Demand Switch is an electronically controlled mechanical circuit breaker (MCB) that replaces the 230 volts AC with a low or a DC voltage that is then used to sense when a switch is closed, when the 230 volts AC is automatically re-connected to the circuit. These can be fitted in consumer units and wired in series with the circuit-breaker or fuse. It can switch 16 amps and be used for lights (one or two circuits protected at 6A, or one at 10A and one at 6A) or radial power circuits (with a 16A MCB in series, one Demand Switch for each circuit). We do not know of a 30A one suitable for UK ring final circuits, but we would anyway always recommend splitting every ring final circuit into two radial circuits. They will each also need to be protected against overload using 16A MCBs. It is usually necessary to install another consumer unit next to the existing one to take the demand switches. It is often easiest to have all the Demand Switches in the new consumer unit and keep the MCBs and RCDs in the existing one. The demand switches are fitted after the MCBs before the cables go off to the lights or to the power sockets. Demand switches do not offer overload protection.

Our electrcians can advise you and your local electrcian on how to install these devices. Once purchased we will also send you an information sheet on how to reduce the electric fields in your home.
