busbar to provide a double earth facililty for use
when installations require additional earthing
capacity and are to comply with Regulation 607 of
BS 7671 IEE Wiring Regulations. These should be
referred to for specialist installation guidelines.

For normal installations either or both earth
terminals may be used. See figure 4 for typical
terminal layout.
