New member fitting single oven flex

[Bushy-Beard]

The vertical chase is required to be in a 'safe zone ', which is anywhere within the width of any of the three fittings grouped together.
Electrically, it is probably OK, as long as the spur to the microwave is directly of the RFC ( assuming that's what feeds the three fittings), but to be compliant, the vertical chase needs to be moved to the right. Definite C2 on an EICR as it is.

I don’t believe it this bloke argued with me by text saying he has certs and he will bring them to show me lol when he should have done a professional job in the chasing and regs iv now got to re chase the walls deep enough to bury cables and found earths not on some back boxes and I am sure this isn’t right (pictured) I would have put 2esrth to switch and one to metal box ? Or am I wrong ? Lol
I only wanted to know how to get the oven wired in lol it’s amazing how many faults I found and by your good selfs I guess this is what happens when money is short appreciate your help

If you drop the mcb down to 20, (16 would do?)
you don’t have to change the 6mm cable.

Ensure it is rcd protected.

Hi so if I fit a 16amp breaker keep the 6mm cable can I run a length of 6mm from the appliance socket that will be behind the tower appliance unit to a fused spur above worktop ? What size back box as 25 is really tight with the cable size
Thanks

As the cooker is a fixed load, then presumably the manufacturers have designed the size of the flex accordingly.

Can’t see that mentioned here?

I spoke to an electrician and he says a 6 mm cable should be run to a cooker connection plate off the existing red oven switch on wall now then run a switch to inside the tower unit above oven for the isolation switch?

If the breaker is reduced to 16 or 20A, then the added cable can be 2.5mm2.
25mm box is for light switches. 35mm for 'normal' socket wiring and 47mm for anything involving 6mm2.

You can get 25mm for normal sockets, but easier with 35… sockets with usb require 35, and some smart light switches need more than 25.

47 for grid switches
