7 Wrap a layer of PVC tape from bottom to top, starting from 25 mm (1 inch) below and
finishing 25 mm (1 inch) above the edge of the self-amalgamating tape, over lapping at half
width.
8 Repeat with a further four layers of PVC tape, always overlapping at half width. Wrap the
layers in alternate directions (top to bottom, then bottom to top). The edges of each layer
should be 25mm (1 inch) above (A) and 25 mm (1 inch) below (B) the previous layer.
9 Prepare the metal grounding point of the supporting structure to provide a good electrical
contact with the grounding cable clamp. Remove paint, grease or dirt, if present. Apply anti-
oxidant compound liberally between the two metals.
10 Clamp the bottom lug of the grounding cable to the supporting structure using site
approved methods. Use a two-hole lug secured with fasteners in both holes. This provides
better protection than a single-hole lug.
