downgrading a cooker circuit

[Gringoking88]

Hi all,

Tomorrow I am installing a cooker circuit and the client wants me to install 6mm on a 32amp breaker as she wants the flexibility moving forward to upgrade her cooker to a more powerful one.

At present her new cooker's instructions say it must be hard wired and protected using a 13amp fuse. Im looking for advice please on how best to add the fuse protection, e.g. would you take a feed from the connection unit to a FCU and then to the oven or would you feed a 6mm to a 13amp FCU and wire straight to this baring in mind its on a 32amp breaker?

I know its a basic question and apologise in advance so please be gentle. I am registered with NICEIC but hardly do any work tbh so am not involved full time and only tend to do small jobs for friends etc and want to make sure im doing this as safely and best as possible.

Many thanks,

M

Gavin,

Believe it or not, the oven was wired straight into the terminal block shown in the photo. I was thinking the following setup; MCB on board - 45amp cooker switch - fcu with flex outlet to cooker.

^ Above - was the existing oven on a 13 amp plug socket then? i had assumed it was on a ccu and you wanted to change it to a fcu? but why have a fcu where it cant be reached? it sort of defeats having a switch if you cant use it

Gavin,

Believe it or not, the oven was wired straight into the terminal block shown in the photo. I was thinking the following setup; MCB on board - 45amp cooker switch - fcu with flex outlet to cooker (based on all the helpful info above). Mainly because it would make it simple to upgrade.

Westward,

Cheers for the tip, funily enough I ordered 46mm lol but who's counting!

Won't be deep enough you need 47mm.
