Pls advise on layout/location/3 phase board

[WWilts]

Just commenced enabling works.

Electricity connection due soon. 3 phase 46kVA.

 

No idea:

 

1) Where is best to put the 3 ph distribution board. In the kiosk? And where to put the kiosk? (It is as far from the road as SSE offered). What else to put in the kiosk (eg., switched fuse(s)?)
2) How to provide power to builders. What gadget(s) to use. Novice here, so pls assume zero knowledge.

3) How to take power to the new build in due course? Keep the 3 ph board in the kiosk and take single phase supply to the new house? Use SWA?

4) Where to put EV chargers eventually. And whether to put in some cabling at this stage in preparation.

 

Grateful for any advice.

Put a small 3 phase board in the kiosk leaving plenty of room for the supply head and meter.

 

Power to builders is via one or more 16A commando sockets fed from 16A rcbo's in the board. These must be earthed to a local TT earth not suppliers earth.

 

Supply to house can be single or 3 phase using appropriate size SWA and mcb.

 

EV chargers can be fed direct from the board in the kiosk, earthing depends upon charger used. 

 

Sewage pump can also be fed from the board in the kiosk.

Hi @ProDave & other gurus
Would ducting/trench be useful to run the SWA from 3 phase board to house? Sewage pump too will now be positioned near house.

Currently there is an open trench and (separately) quite a bit of 100mm electrical ducting lying unused although paid for already. Ducting in trench currently extends from footpath to meter box kiosk only. The trench then continues on to near the house, carrying water barrier pipe / gas pipe / ducting for eventual telecoms or fibre cable / one spare duct.
