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

To be honest Falcon you have entertained me with this Fawlty towers project, and i have only just realised it is friday so this is quite Apt.
For the record we get a few post's like this on a friday.

Oh yeah, it's Friday. Yep this has been a good thread

Go on share!

We could do with a laugh, I'm in brum so if you need any advice give me a shout!

As I just said in PM, if they want a board in each room then there are 2 ways to do it..........

16 way 3ph DB on each floor and a box of C32's. 9" tray and 35 x 4mm radials (which probably are not going to be that much more expensive than 10x 10mm radials with 4 points of connection each)

Or......

200a 3ph busbar all the way round the corridor ,
Rip all of the supplies out and fit a panel board downstairs. 100/120a 50mm SWA up to each floor and use tap offs to spread load, use a tap off to supply a communal DB for the corridors.

Legrand are in brum so a nice bit of zucchini busbar !!

Sounds a great idea........................Not.

Everyone gets back to their room at the same time (who are in one of the 4 rooms on the same circuit),

Switch the lights on as they get in the room as it's getting dark

Put the tele on

I'm going for a shower love! lights go on in en-suite

As it's a bit cold, Lets put the heater on,

Oh lets have a cuppa love, Kettle goes on,

Bang everything goes off

Glenn, it's not a case that falcon is incapable of designing the installation. It's more of a case of not having the confidence to stand by his own ideas and risk loosing the client and the job!.

We all know wah it's like to have somenumpty who has his own idea of how it's done but not a clue, telling us how to do the job.

 

[Pete999]

as I said this was there idea, and was racking my brains over this as ive never done it before or been asked to do it, I told them that it should be lsf twin and gut at least but they don't like that either !

lsf twin and gut?

I would not feed a socket off a 10a mcb as the first time someone plugs in a microwave or trace stove it will pop and how basic the install sounds, makes me think it's a bit of a budget hotel, so the kind of places that would have guests bring such equipment. My lads who are staying at a park in in Liverpool have got a microwave, kettle, iron, play station etc

I totally agree with you mate but he needs to gain the confidence quickly, i am sure you will agree, that this is tasty job to get.
However unless Falcon either convinces them to go with his design, or get's them to sign a Water tight contract that resolves him of any blame or financial cost when it start's to go pear shaped, he would be better off walking away.
While this could be a great contract to get, it could also be a monumental headache.

 

[falcon0310]

headache ive had that for 2 days, problem that we all have is I only here once or twice year what most expensive I can have, and there normal dogy wanting pay in cash
