In a UK domestic dwelling would/should you wire an oven and/or hob in H07 Flex or T&E (PVC/PVC)?

Sergio Fernandez

Some MI (manufacturers instruction) for oven and/or hob state H07. 

Some MI for Cooker Outlet Plate state T&E. 

Some MI for the oven and/or hob/Cooker Outlet Plate lack any guidance and say consult a qualified electrician. 

Another thing to consider is, if the MI for oven and/or hob state H07 and MI for Cooker Outlet Plate states T&E, are they incompatiable?  Personally I think H07 Flex should be used for Oven/Hob thus the oven/hob can be removed for cleaning or maintenance purposes.  It is also heavy-duty rubber designed to provide high flexibility and to withstand chemical, mechanical and thermal stresses and normally UV stable.  It would be nice to see what BS7671 states and what the community thinks and what the manufacturers state or  think.

  • I would consider that HO7 flex is preferable on the grounds of flexibility and heat resistance, but that twin with earth is just about acceptable

    Would I install a cooker in twin with earth ? Probably not.

    Would I give an adverse code to an existing twin with earth to a cooker, no I would not unless stress or damage was observed

    H07 might not be suitable for some heating appliances, due to temperature particularly at the terminations or close to the appliance ... same problem with "standard" PVC, whether rigid or flexible.

    I know some people in the industry would go for "heat-resisting" flex rather than a 70 ºC conductor operating temperature cable.
