Hi All

Regulation 6.11.4

"Where conductors from more than one supply are connected to the main earthing terminal, each conductor connected to the main earthing terminal shall be able to be disconnected individually without having to disturb any of the other earthing conductors, irrespective of the number of supplies."

My queries are:

1. What is meant by " from more than one supply " ?
2. Does a single phase domestic installation have one or more supplies ?
