Thorfun Posted July 6, 2020 Share Posted July 6, 2020 (edited) Hi all, we are planning for the electrics for performing the build will be run from our existing house. we have a 'pool house' which is shown in the photo below which has an RCD in it with a connection from the main RCD in the house. This powers the heat pump, water pump and lights for the pool. as well as having a couple of household sockets in the pool house for plugging stuff in to. the pool house is being demolished as that's pretty much where the house is going so I was going to get an electrician to move the RCD unit that's in the pool house to somewhere else on site and let the builders take their electricity feed from there. the cable running to the pool house from the house goes from the right side of the pool house to the house you can see to the right of the picture so I would assume it would be easiest to dig up that cable and move it and the RCD to somewhere within the length of that existing cable. so my question is, what sort of electricity will the timber frame company need? is a 110V supply required or can I just get the electrician to give a line of household sockets for them to plug in to? also, is there a required distance from the electricity supply to the new house so the use of long extension cables is reduced? and finally, what would be the best to house the RCD in? I'm planning to repurpose the pool house to be the site toilet near the house wall (by the bright blue water butt you can see). so could I attach a box to that structure and put it in there? I hope that all makes sense. I haven't yet asked the Timber frame company what their requirements are (I probably should do that!) nor have I spoken to an electrician yet as I wanted to get an idea of what I need doing before getting quotes in for the work. oh, almost forgot, we're getting a new supply run to site in another location (near the new entrance that will be built) so eventually the existing supply to the current house and pool house will be decommissioned once the new house is built and we demolish the bungalow.

ProDave Posted July 6, 2020 Share Posted July 6, 2020 All your electrician needs to do is connect a few waterproof sockets. Remember to connect them to a TT earth (local earth rod) If the builders want 110V they will bring their own transformers. A couple of 16A "commando" sockets would be handy as well as standard 13A sockets. Link to comment Share on other sites More sharing options...

ProDave Posted July 6, 2020 Share Posted July 6, 2020 The site supply needs to be far enough away so that it is not in the way for scaffold, diggers and other works so 10m seems a good distance. 1 Link to comment Share on other sites More sharing options...
