Help on 3 phase in domestic house

[Bishop_mike]

Hi I have a few questions I'm taking over from my uncle who passed away and need some advice
I have 3 phase I comming too the building and they want too change the lighting board from a mode evolution too a Lutron control system. But old board was 3 phase newboard isn't
my question is can I use Each phase (L1,L2,L3) on separate mcb and split the load a cross them total load is 6000w

If you need more info please ask

6000w for lighting in a domestic property??? What is it? A mansion?

Ive got 4 bedrooms, office, lounge, dining room, kitchen, hall, landing, 2 cupboards and that only adds up to 1200w even if 100w st each point, plus 4 security lights at 400w, even then at most I can only draw 3.2Kw.

If the Lurtron controller is only single phase then you'll just have to stick with one of the three you've got. As a previous poster has said, 6000w seems a lot but a three phase supply seems strange also. If there aren't many big loads other than this you'll have to try and make it the only load on its designated phase.

That load is for 5 bedrooms 2 hall and landing. 5 bathrooms that's jus the top 2 floors all with low volt lighting so jus counted fittings

[/QUOTE]I'll try post pics of what I'm working with might make it clear

 

[Bishop_mike]

It's a big house with ac and over 350 down lighters
goin too post some pic might make it easy too understand what I'm working with

 

[Bishop_mike]

Not sure if I can post pictures too make it easy too explain but will try

You should be able to attach images to your posts, otherwise you can upload them to Photobucket or a similar site and post a link here.

A bathroom for every bedroom, I don't buy it, id like to see some photos.... Do you mean low voltage or extra low voltage? Low voltage ac is 50ac - 1000ac and extra low voltage is below 50v for ac. If you have 350 down lighters with normal lamps in say 35w, then that's over 12Kw, but if they are LED they might be as little as 1.5Kw. I'd say if you have a three phase board, keep it, why go backwards and put make it single phase boards.

Glad I'm not paying the electric bill . Daz

 

[Bishop_mike]

Not changing the I comming board jus the lighting board they supplied isn't 3p
but the total lights for whole building is just under 12k. The 6k is just for top two floors
cant see how too post pics, photo bucket ain't working at the moment. Lights are 50w low voltage lamps

 

[DPG]

It seems to be the current trend to have more downlighters than your neighbours. I've seen kitchens with 20+ halogens in them. Crazy. Daz

Just because neither you nor I live in a mansion (I assume), doesn't mean that they don't exist. An en-suite bathroom for every bedroom is 'de rigueur' in all the best houses nowadays.

Lol at a job near Hyde park it's huge split over 5 floors every bed room has bathroom master has own floor with TV room and a bathroom bigger than my living room and dining room put together lol they even have a maids quarters with her own bathroom in the basement

Ok added pics too photobucket now how do I get them on hear?

Just copy and paste the image link

I just find it a bit far fetched, not saying its not true, but you initial said the total load across the three phases was 6Kw. So 350 down lighters at 50w = 17.5Kw, which is 5.5Kw more than your comment in post 19, that's like 32A just on lighting. I appreciate you get some big houses, but that just sounds way over the top and unrealistic, if its true that's very good but I don't buy it. But yes, I agree, I don't live in a house of that size, I know they exist, but just think the figures keep changing and don't add up. Please prove me wrong, ill eat my hat and shoes at that!

The other thing, obviously a house round there is going to be old, and I dont know, more likely to have traditional lighting and high ceilings maybe, just airing my thoughts, but 350 downlighters? Seems out of character for the location / possible style of the house.
