Ok I know this is dragged up time and time again regarding the 3a fuse on a fan debate but i had an interesting one today.
i am installing a belling 100dft range cooker, the manufacturer's instructions are tight lipped about the actual wattage of the bleeding thing but the info I got was that it needs to be protected by a 32a mcb and also in the manufacturer's data it says that you need to install in 6mm t&e.
The cable run is relatively short, voltage drop is ok and reference method is C - clipped direct - IE clipped direct to a joist with no insulation around it and also chased in for a short run down to the cooker isolator (correct me if i am wrong but this is my understanding of the reference method C), for this reason I decided to go for 4mm t&e protected by a 32a mcb - CCC is 37a so ok for a 32a mcb. Now technically this is against the manufacturer's data but I would claim common sense on this one - the manufactirer's data probably assumes that the person installing may have no idea about cable calculations and could be installing in loads of insulation etc so to save the job of calculating they over spec with the cable size. Would you agree??
Ignoring the "best practice to use 6mm for the future" aspect do you think i was right or wrong
in this instance???
Thanks a lot peoples
