spur off a cooker circuit

[Mfctitch]

Hello everyone
new to this so please bear with me.
Was asked to supply an outlet for a washing machine in a kitchen with solid walls and solid floor.
I believe that the cooker should be on a dedicated circuit. My problem being that there are no other sockets on the same side of the wall.
Can anyone explain why I can not come off of the cooker circuit with a fused RCD and a single socket fitted to a double box. seeing as the cooker switch already incorporates a socket as well.

Thanks in advance for all advice.

Sorry notsosmart and Pushrod I missed the word "fused" rcd in the op.

As you've said Pushrod if this is the only practical option and if its done right there is nothing against it and its better than having extention cord in consistent use.

Anything over 2 KW "should" be on its own circuit, or "recomended" to be on its own circuit


It is a radial circuit supplying a known load,its a load which may in the future be altered and be increased to require the full capacity,thats why its probably recomended

The wiring regs do not restrict the use of alternative circuit arrangements which differ from those suggested in the guides
If the current carrying capacity has leeway for extra loading that can be carried by the cable,what safety wise would be the concern ?

Its not the done thing to normally construct a circuit this way,but circumstances may dictate other methods
If you condemn the suggestion,what are your reasons for doing so,other than saying its not the norm


If a socket is taken from the cooker circuit,its not much difference to a second cooking appliance, which is permitted

Being new to this and the fact that it's late I don't know how to say thanks to you all so I'll say it here.
Thanks again for all of your advice. I will of course label the fused Rcd and the fuse in the cu.

Installation method for the whole run, thermal effects of insulation around the cable, wear and tear during and subsequently to installation of the cable (insulation degradation), vermin attack, connection of a spur somewhere within the run by a DIYer etc ~ if the cable is then taken up a notch towards its capacity there is a chance (admittedly slight) that the insulation could start failing ~ most, if not all, of which can be determined by a full inspection, but the inexperienced hardly ever do.

Not my favourite practice but I accept sometimes needs must, however this would be my very last resort.

A method of determining the above would be by assessing the very items that you have now listed

An inspection has no bearing on the question of the "principle" of whether it should or shouldn't be done
The inspection would suggest whether or not it has the "capacity available" or not



but the inexperienced hardly ever do.
Unsure of what or who that was meant for

hey, I know this is an old thread but I came across this the other day doin a periodic, the kitchen sockets were all spurd off (2.5 t+e) the dp cooker switch (6mm t+e) 30 amp rewireble fuse, I failed on the basis of ineffective overcurrent protection because its a radial protected by a 30 amp breaker, however if it was a 20 amp breaker I would have found it hard to call it dangerous, anyone else have any thoughts on that?
