Is it ideal to have the lighting ciruit in a big kitchen around 600watts in total on a ring circuit like a mains ring or not? and how would you incorporate a switch into the loop. I have my own thoughts but not sure if correct.

Thanks

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.

I have my own thoughts but not
sure if correct.

Worrying......

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.

Do you understand what a ring circuit is? Lighting circuits can have large
supply cables to them, then distributed from that to smaller gauge wiring
for the switches and lamp holders. To run a ring circuit using two supply
cables from the consumer unit (fuse box) shouldn't really be necessary.

Having lighting at 600 Watts in one room is a hell of a lot. What else do
you do in the kitchen that it needs all that lighting? You don't make porn
films in there do you? :-) If the lighting is made up of 6 x 100 Watt spot
lights, then try and drop this down by using low voltage spots on good
transformers. You can distribute the light from these better than huge spot
lights.

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.

My kitchen would definitelty benefit from more than the 9x50W spots amd
3x60w candles it has ....I would say a kilowatt would not be amiss
frankly, but its a big kitchen.

But as others have said, ringing it gains very little apart from extra
complexity in cable laying.

Light circuits by their nature are full of switched spurs and switched
links.

Better to us fatter cable on teh run from MCB to the first switches.

But better still is to have a single 6A MCB, and wire it just like
everyone else does, to avoid confusion when a dumb sparkie eyeballs it
some time in the future.
