Do I need a Schematic Drawing of our electrical system?
It is evident from the BS7671 excerpt (below) that documentation is an essential requirement for all types of electrical systems. There is no ‘one-size fits all’ type of diagrammatic representation of electrical systems but in practice a one-line diagram or Schematic Drawing is an efficient way of capturing the essential information.
Schematic or one-line drawings are particularly important in the event of a failure necessitating the need to install temporary power or to wire around in order to restore the operating system.
