Electric Heater

goldenboy1818

Hi guys, on a house and they would like a outdoor patio heater fitted. It's only a small 1.5kw heater so we can add a spur off the kitchen/lounge ring. However in the manual it states it may need a type c mcb due to in rush current. Is this definitely needed ? Its currently on a hager type b 32 amp rcbo. Thanks

    If a 10 amp MCB was used, as is common in some places, then a type C might be prudent to avoid tripping on inrush current.

    A 13 amp fuse and a 32 amp B type MCB should be fine. The fuse is rated for about twice the running current and the MCB at about five times the running current. It is presumably a halogen lamp, and these are routinely used from standard 13 amp fuses and standard types of UK power circuits.
