11kV Portable Earth Sets
11kV earth kits are supplied with spring loaded snap on clamps as standard. 3 phase leads are connected to the earth lead via central cluster star point, a cluster bar is available as an alternative.
Where safety rules dictate that the crossarm should also be earthed an additional phase lead with CE10 crossarm clamp can be added to the star point or cluster bar. If more convenient, the crossarm lead can be supplied as a separate item with the CE10 clamp one end and a CE62 snap on clamp at the other end. In some circumstances a separate 6m bond lead is requested with S9AH clamps each end.
