Grid Switch, Best Way?

[ToastyToaster]

Hi all,

Attempting a Grid Switch in my first home and having a nightmare finding the best way to wire this. Seen a lot of posts and can't decide which is the best/safest way to install this. I am using MK 20A Grid Switches and 2.5mm cable. Below is my initial plan(s) please let me know if either is fine or if i need to make a few changes, Cheers.

Maybe that is because it doesn't really matter which way it is done.

It is up to you.

I wouldn't bother with grid switches at all.

Both result in a massive load at a single point on a ring.
Both are entirely pointless, along with the whole concept of having a rack of switches that will never be used.

The oven can have a switch near to the oven.
Everything else plugs in, removing the plug is the isolation.

Grid switches are awful devices, especially with ring circuits - see far too many failed that need replacing and its definitely not ideal to have the washing machine, tumble dryer AND oven on it.

Do it properly and don't waste time and money on it

Scottish building regs (technical handbooks) say:
"Where socket outlets are concealed, such as to the rear of white goods in a kitchen , separate switching should be provided in an accessible position, to allow appliances to be isolated". I thoroughly approve after I got a shock from a 'class 2' cooker hood. MK switches aren't very good, I'd recommend Schneider. Just don't put the fridge/freezer on it (accessible socket or it's own out-of-the-way switch). So long as it's suitably designed and properly installed no current over 20A will be in any part of the ring - absolutely fine for 20A switches.

I have a schneider without problems (so far) fitted for 4 years
