Title: wiring 3.3kw oven
Post by davygravy on Feb 21^st, 2014, 7:47pm

Any help please,I have purchased a 3.3kw oven,now I know this will have to be hardwired to supply.I know I have a 45A feed from the consumer unit to cooker socket,would this be ok to feed from the socket to a cooker outlet then to the oven,or would 45a be to powerful for the oven,any advice,thanks

Do as you suggest, but swap the MCB for a 16 amp one.

What make is your fuseboard? Photo?

Assume no lecky hob?

Will 16a be ok going through 10mm t&e?

10mm is nicely oversized. Better too big than too small.

The MCB does need changing though. Hagars are readily available.

6mm t&e will be ok from outlet to oven though won't it?

2.5mm would be ample, HO7rnf preferred.

4mm would be my choice here.

I would probably go with 2.5mm HO7 flex as some of the terminal enclosures arent designed for anything bigger and many ovens of that size will come with a 1.5mm flex
