[QUOTE="Phoenix, post: 558104, member: 8133"] Yes its dedicated circuit back to the board Generally 6mm but may need to be bigger in some circumstances. In most situations you need a twisted pair of signal wires with it for the CT clamp for the maximum demand protection Desn't need to be SWA unless its being buried, but if its going outside, needs to be UV stable, NYY-J cables are often used Shouldn't be downstream of any type AC RCD, requires its own double RCD, and is inadvisable to be downstream of the same rating of A RCD - This often means a replacement or additional board is required - pictures of the existing would help confirm this. There are often ways to route cables which can be found on site, is it just the ground floor thats got laminate, or the first floor as well? Bear in mind, the national companies(often twinned with energy or car car firms) like to try and do as near enough a standard install as they can and give one man about half a day to get it in, this sometimes ends up with it not being routed as you'd prefer, often you'd be better going with a local firm who do EVSEs alongside most other electrical work, who are probably more flexible in your approach [/QUOTE]
