Underground direct-buried cables are normally spliced using which arrangement?

• A. Plastic splice box and a tape splice kit for the size cable to be spliced
• B. Prefabricated cable splice kit is used to splice the cable
• C. Thermoplastic splicing module is used to splice the cable
• D. A new cable is pulled in to eliminate the need for a splice

Answer: (A)

Direct-buried cables are joined in a moisture-proof enclosure so the splice is protected from dirt and water and can be accessed for maintenance. The typical setup is a plastic splice box housing the splice, with a tape splice kit sized to the cable used to insulate and seal the joint. The plastic box keeps the joint safe from the elements and damage, while the tape kit provides proper insulation and moisture barrier around the conductors. This method is generally quick, cost-effective, and suitable for field work on underground cables. Other approaches, like pulling a new cable to avoid a splice or using a different type of prefabricated or thermoplastic module, aren’t the standard arrangement for direct burial in most situations.
