Is it ideal to have the lighting ciruit in a big kitchen around 600watt
in total on a ring circuit like a mains ring or not? and how would yo incorporate a switch into the loop. I have my own thoughts but no sure if correct.
Thank

No, not recommended at all.

No. It's certainly not a standard circuit and nothing would be gained.
The standard 5A/6A lighting circuit is enough for 12 ordinary points (each point must be considered as minimum 100W, or actual load if greater).

You can't switch parts of the ring, or it would stop being a ring. You can only switch spurs from a ring, which is why it's a bit pointless using one for lighting. Unless of course you are lighting something the size of a football stadium, when it might be useful to use a ring to reduce the cable size. In that case though the whole ring would be switched on/off. And it wouldn't have a 6A MCB on it either.

Absolutely not. Your general purpose kitchen ring circuit would preferably be RCD protected, which would not be appropriate for the lighting circuit. It would be far better to put it on a lighting circuit. If there is not an existing circuit with sufficient capacity, then you should install a new additional circuit.
BTW, 600W is an extremely large amount of wastage. You should consider redesigning your kitchen lighting replacing grossly inefficient halogen spot fittings with energy saving types.

No. It is totally unneccesary.
Simple if you know what you're doing.
Worrying......
Hi I don't mean ON a mains circuit i mean on its own but LIKE a rin
circuit

Oh, sorry for the misunderstanding.
There is no point in doing so. The 1mm or 1.5mm cable used will have such low voltage drop and such high current capability that it will just complicate matters, particularly when it comes to testing. However, there is nothing in the regulations preventing you using this circuit configuration should you wish.

1, Don't top post. 2, Reply in context and in the correct place in the thread 3, If you don't understand all the answers, which you obviously don't, then leave it alone and get someone in who does. 4, Don't take this personally.
I appreciate you mean "like a ring", however the answer is still no.
A single run of 1mm sq csa T&E is good for 12A even if burried in insulation in a wall. So it will already cope with double the typical MCB size you will use for a lighting circuit.
Your 600W of lighting still leaves another 800W of headroom on a standard 6A MCB, or enough capacity for another 8 standard light fittings.
