dasy chaining boards ?

[falcon0310]

a big hotel group has asked us that they want 2 way dbs in each bedroom feeding one socket and 5 lights all led fittings, but they want the supplies to boards daisy chained from 10mm t&e or swa feeding 4 rooms per circuit. the only way ive ever done this is sub per board, but cant find anything in the regs, as so many jobs this is to save money but surely its not right

the hotel has 150 rooms, with so called electrical expert, that wants board per room that does make sense so only board in the room can trip out, so I agree but never have I looped board before, there other idea I cant even say as worse

this is not my idea its there's !!!!!!!!!!!! save money on cable we all know that you should have one supply per board

That's why I'd go back to them with a written summary outlining why it shouldn't be done and staying reg numbers!.

Also testing and certificating this would be a pain.

Multiple 10mm radials is not going to be all that much cheaper than individual 4mm's

Could even look to put multiple section boards on the floors if it's a big place.

Oh go on, you need to tell us now lol.

It wouldn't be selsdon park would it ?

Stand up to them and tell them it's a bad design, as for installing an 8 module board, well that's just plain daft

you need few couple contactors and so 2 spare mods for room in the board think its £2 difference

Falcon you know this is not the way to do the job as you have said, so you need to sit them down and explain it on a level they will understand. If you go with this design believe me you will be getting called back constantly, and they won't want to pay because they will blame you.
Regarding the " Electrical expert my advice would be take him to the top floor of the hotel, open a window and throw him out.

Explain to the client that if the SWA ever has a fault then they are looking at 4 rooms of for maintainence until it can be sorted!

Hotel management dislike nowt more than having rooms off!

8 ways are 8+ main switch mate so you probably only want 6 ways!

Get them to spec baby hagers, bambino sight easier to terminate SWA's into and easier to move the guts about!
