No earth cable on new kitchen cooker extractor

[adrian_uk17]

I have just finished fitting my kitchen and installed new cooker extractor/free standing chimney thing.

Put new wiring in via switched circuit from main ring kitchen circuit, not fused at the moment but intend on changing this.

My main concern is that the cable coming from the fan and light etc only has live and neutral and no earth.

I may be dumb here but surely the case should be earthed, the instructions said nothing but my general instict says it should be.

Does anyone have any recommendations?

If the manufacturers of said extractor fan have designed it to be double insulated then there is no need to earth it.
On the wiring diagram in the instruction booklet ,or on a sticker usually located inside the casing of the fan, it should state, if it is ,indeed double insulated or there may be a symbol used i.e a square box with a smaller square box inside.

Remember most extractor fans need local protection that is usually in a 3amp or 5 amp form. I suppose there may be fans out there that may need 13amp protection but it all depends on the rating of the fan itself.

So if your going to connect it to your ring (32amps) or radial (16/20amps)
that will not offer the correct protection and an SWITCHED FCU (with 3,5 or 13 amp cartridge fuse) should be used.

Festa thanks for the rapid reply, i have a feeling it is double insulated as the fan motor and light are all encased in a separate plastic housing!

I will replace the switch with a fused Switch unit today!

Thanks again
