We are building a high end residential project where the employer have identified group of electrical outlets and the dimensions between each socket. We have done a great job which does not disturb the nature of high end job but the client's architect snagged each and everyone claiming there are zero tolerance for dimensions between each sockets and levels of socket groups. Can you let me know which British Standard should I use to refute this snags as I believe every installation has a tolerance in UK. Thanks in advance.
