Direct Burial conductors that are spliced must have the splicing means _____ for direct burial.

Direct Burial conductors that are spliced must have the splicing means _____ for direct burial.

• A. Listed
• B. UL listed
• C. Factory sealed
• D. Not required

Answer: (A)

Direct burial splices must use a splicing means that is listed for direct burial. This means the device has been tested and approved by a recognized testing lab for underground use, ensuring it can withstand moisture, soil chemicals, and mechanical stresses without compromising insulation or safety. Using non-listed methods can allow moisture ingress, corrosion, or insulation failure, creating the risk of short circuits or fires. Factory sealing alone isn’t a guarantee for direct burial unless the item is specifically listed for that purpose, and “Not required” is incorrect because underground splices need a approved, protective solution.
