Which step is associated with sealing a cable?

• A. Remove outer jacket 2 in
• B. Apply sealant to insulation
• C. Install grounding wire
• D. Cut the cable to length

Answer: (A)

Exposing the insulation is necessary to form a proper seal. Removing the outer jacket—about two inches back—provides clean, bare insulation for the sealant to bond to and for the sealing material to create an effective barrier. Without stripping the jacket, sealant wouldn’t adhere or seal correctly around the insulation and conductor boundary. Cutting the cable to length or installing a grounding wire aren’t involved in creating that seal, and applying sealant to insulation is the sealing action itself but only after the jacket has been removed.
