Which other insulation types are mentioned as suitable for limited-energy cabling?

• A. XHHW and USE
• B. XLPE and PFA
• C. PVC and PE
• D. EPR and SJE

Answer: (A)

Limited-energy cabling requires insulation that can handle moisture and temperature stresses in the environments these cables encounter. XHHW and USE fit that need well. XHHW is a cross-linked polyethylene insulation that’s highly resistant to heat and moisture, suitable for both dry and wet locations. USE stands for Underground Service Entrance and is designed for underground or damp locations, offering extra moisture protection and flexibility. Together, these two insulation types are commonly mentioned as appropriate for limited-energy circuits because they provide reliable performance in the kinds of conditions these cables face. Other insulation options listed don’t align with the typical limited-energy setting. XLPE and PFA are more common in specialized or high-performance applications, PVC and PE are general-purpose insulations often used for power cables rather than the specific limited-energy contexts, and EPR or SJE refer to different cord or insulation families not routinely specified for limited-energy cabling.
