B & B Design

sparky87 · Feb 17, 2015

Hi people,

Have a new luxury B&B to design and install and thought I would get thoughts on the design.

Internally it will have a dining area, hall, toilets and, 6 en-suite bedrooms (1 upstairs)

This is going to be a royal pain to wire as mostly is vaulted ceilings with baths located within the rooms!

My initial idea is to supply communal areas via the incoming 3 phase DB and then feed a 25Amp SP sub main to each room. Then wire 20A socket radial and 6A lighting from local DB for each room.

was thinking of using earth shield cable for the sub mains so no rcd required then rcd main switch in local DB or RCBO's for standard T&E final circuits.

Thinking of using local DB's for ease of wiring due vaulted ceilings and then each room will be independent of each other.

Any ideas etc would be much appreciated.

Thanks Adam

lighting is going to be a mixture of pendants, recessed spots (in bathrooms etc as these will have false ceilings, wall lights etc so will be clipped around the top of walls and up roof beams above selotex using 1.5 t&e with rcd protection

t&e cables will be in standard safety zones and swa outside of zones if required as they are swa so permitted out of zones.

OK it seems my last post was unhelpful.

You’re asking a group of random guys on the web how you should do the electrical design for a “luxury B&B”.*

From reading your posts the plumbers have got their act together and are ready for laying the screed, you on the other hand haven’t even got off the drawing board.
I’ve not much experience of domestic/commercial installs but shouldn’t you be most of the way through the 1[SUP]st[/SUP] fix at this point? Once the screed is set the plasterers will be tugging at the leash to get started.

Would you care to explain just why you’re so far behind in the design?

*The last time I had anything to do with a “luxury B&B” it was a brothel. I hired the place to hold private parties.
