50 Amp Cooker switch

[stretchyboy]

Does anyone know of a 50-Amp 1-phase cooker switch for a domestic job that would look nice alongside Hamilton flatplate brushed steel finish other accessories?

Everything seems to be 45-amp or industrial, nothing looking stylish at all.

Help guys

Is it a new installation?

 

[stretchyboy]

Yes it is a new extension onto an oldish house, but they have opted for a humungus cooker

63a contactor below units controlled via hamilton plateswitch

Clever..........., you may have come up with the ideal answer. Any issues that would arise regarding the switch being the isolation point (need to be lockable) or any failsafe issues (My old London Transport head kicking into gear now) ;-)

Put a 45A switch on!

NO - you cant lock off a cooker control unit - lockable dron OCPD

If you read the blurb on the cooker you wouldn't even chance it, it clearly states that it MUST have a 50-Amp isolator.............. besides I dont want to spoil our unblemished public liability

 

[piggyitm]

Allow for diversity,first 10a then 30% of remainder.

Err the requirement is a 50a isolator

what is the power rating out of interest

 

[stretchyboy]

Yep the manufacturer says - MUST be a 50-Aamp isolator - therefore it MUST be a 50-Amp isolator. It doesn't matter what calcs you do, you cant supercede a direct instruction from the people who make the kit.

what is "lockable dron OCPD"? It's probably too late at night to do puzzles for me and it will turn out to be something simple

For a start those 45A cooker switches can take 50A, ...No Problem!!!

Further, I doubt very much you'll see anywhere near that 50A for more than a couple of minutes or so, at the very worst.... These cooker manufacturers always seem to quote connected load, never maximum load that can be used. There are heating elements that can't be used simultaneously with other heating elements, such as the main oven and grill elements... Use the Diversity formula on the actual load that can be utilised simultaneously!!!
