New Tractor Shed
awemawson:
While Darren was roofing, I unpacked an electrical delivery that came yesterday - the 3 phase distribution box and it's entrails, and also the three internal and one external 100 W LED flood lights.
I'd worked out that I needed eight electrical 'ways' in the board:
1/ 50 Amp 3 phase feed to external electrical distribution point
2/ 32 amp 3 phase 'socket 'radial'
3/ 16 amp 3 phase 'socket radial'
4/ 16 amp 3 phase service for roller shutter door
5/ 32 amp ring for single phase sockets
6/ 16 amp ring for single phase 16A 'commando' sockets
7/ 6 amp internal single phase lighting circuit
8/ 6 amp external single phase lighting service
Although 8 way boards are available that would leave no 'expansion capability' for the future so I am installing a twelve way board.
I am also incorporating a 30 mA RCD which involves installing a conversion kit in the board to couple the RCD to the bus bars hopping over where a simple isolator could have been fitted. I've fitted several of these kits in the other buildings, but this one proved a pain until I realised that the "ISOLATE BEFORE REMOVAL" label had been stuck on upside down :bang:
Then I went on to test each LED floodlight - all worked :thumbup:
awemawson:
The eagle eyed amongst you will notice that there's an extra 3 phase breaker in that panel - I had it - it may as well live there unused - and it save blanking off another way :ddb:
So weather permitting tomorrow brings a bit more roof sheet screwing down and hopefully some side sheeting going on - watch this space :thumbup:

The forecast (BBC) for your area looks good for tomorrow until Saturday, except for a brief shower at 06:00-ish on Friday.
If Darren fixed all the roof sheets from above, how did he know where to drill the holes? Did you help him from the underside?
awemawson:
He's a canny lad and has been doing this for years :thumbup:
Actually, as you lay the sheets on the Z Purlins, you can see the Purlin line on the uncovered side, so a quick tape measure from the top or bottom of the sheet gives you the place to drive your self drilling screws .

The weather scuppered my brothers roofing job as well, so it's not just Suffolk suffering! Interesting the way you have done your Disboard, I was faced with this dilemma, and avoided doing it the way you have to save "ways" On my dis board, I used a 45 amp sp breaker to feed a seperate consumer unit with a couple of rcd's for the single phase, thus ensuring all the single phase was on the same phase. Apparently the "electricians" today don't bother ( I asked a few). just slap three sp mcb's in the same way, and put a warning sticker on (if they remember). Don't like that at all!! I would have got hung If I had done that! Aren't they just expensive!! Mine including breakers was about £400, and then I got home and realised there would not be an "incomer" (ridiculous term) in the board. The single phase consumer unit was £30 from fleabay, already well populated with 2 rcd's. Job looks well Andrew, a couple more good days and she will be clad.
