ooker hood

 

A normal cooker hood would be wired up like the diagram here, there will be a switched Fused connection unit leading to either a junction box or directly to the cooker hood. The cooker hood normally comes supplied with a good length of flex which can be connected to the junction box above the ceiling. The wire and the 4" ducting pipe is hidden by the extractor chimney which leads outside, although you can get extractors with charcoal filters which simply filter the air.

Kitchen extractor fans/hoods should be wired into the kitchen ring main via a fused, switched connection unit.
