Supplying electric 400 metres away

Since I fancy a guess, how about the Cob at Porthmadog, built in 1811? Not only a road and a footpath along it, but a very nice narrow gauge railway!

If this is for the Ffestiniog Railway Society, then any help is good, chaps.

Do I signal a yes here? Maybe I have given away too many points!! :wink_smile: lol

The loadings

Lighting 1kw
Heating 6kw
IT 1kw
Kitchen & drain 3kw

Each building is 10m by 4m approx

Any constructive thoughts are welcome.

For me with that kind of loading you would be looking at nearer 40 amp rather than the 63 amp your were looking for. IMO diversity would get that to around 30 amps for commercial property, but make it 40amps for good measure.

4amps of IT is perhaps a little excessive as well and so is the 4amps for lighting. Heating will obviously be your main problem but a well built well insulated building will off set some of that.

Are the above figures combined or for each building

Have you considered a heat pump for heating rather than electric resistance heating?

That would be the ideal solution but, unfortunately, we do not own the shoreline either side to be able to use the sea bed.

Yes interesting thread, just info is so limited... if its a monitoring station you would need to know what is been monitored and if it uses power 24/7 (possible storage heating if daytime only), its possible the quoted demand is correct but need a breakdown, now this isnt my field so not sure on the regs here as it would be out of the scope of the 17th but is it possible to up the voltage then derate at offices... i would also be taking a minimum of 80amp supply with the suggested design load, you just know someone gonner stick an extra Heater or two on.

Off-peak storage heating would need an extra circuit so a separate armoured cable - that is out of the question, I am afraid.

I totally agree with future proofing which is what we have done for the installation at the works on one headland, but we are talking about the other end of the causeway. Monitoring? well, just traffic really, everything goes on outside and it is really a controlling monitor station operating battery powered lights. The second room being the battery room.

I never said off peak in seperate supply you just set up timer and contactor array then the front end meter would then be duel tarriff, thus only requiring the one supply.

You really need to get somebody to come and LOOK at the site. Are you representing the organisation of trying to design it and sell to them?

No - at this point in time, no outside contractors have been involved. I am part of the team in the charity for which my time is given free of charge.

Why don't you contact a local contractor or two and ask them to come and take a look and put forward "rough" pricing - we don't bite, nor charge for such estimates either.
