Practices 4-15
Shield Termination Refer to Shield Splicing on page 3-7 to splice shielded cables. The
following methods are acceptable if the shield connection to the ground is
not accomplished by the gland or connector. Refer to the table associated
with each type of clamp for advantages and disadvantages.
Termination via circular clamp
Clamp the cable to the main panel closest to the shield terminal using the
circular section clamping method. The preferred method for grounding
cable shields is clamping the circular section of 360º bonding, as shown in
Commercial Cable Clamp (Heavy Duty) on page 4-15 . It has the advantage
of covering a wide variety of cable diameters and drilling / mounting is not
required. Its disadvantages are cost and availability in all areas.

Plain copper saddle clamps, as shown in Figure 4.14 on page 4-16 , are sold
in many areas for plumbing purposes, but are very effective and available in
a range of sizes. They are low cost and offer good strain relief as well. You
must drill mounting holes to use them.
