Clamping at the Circular Section
When using a pigtail is not acceptable, clamp your cable to the main
panel closest to the shield terminal using the circular section clamping
method.
Clamping at the circular section or 360
°
bonding, as shown in Figure
A.1 below, is the preferred method for grounding cable shields.
Several types of clamps are shown on the next page. Refer to the table
associated with each type of clamp for advantages and disadvantages.
All of the clamps shown are acceptable for use.
Note: The clamps shown are by Wieland Electric. For more
information on product suppliers refer to Appendix B.
