Allowable Ampacity for 163-23-3084 250 MCM 1C Stranded Aluminum Unshielded EPR Concentric BC Full Neutral 220mils 15KV Okoguard URO-J Cable:100 Amps
About:
This cable is designed for 15KV applications and features a 250 MCM AWG stranded aluminum conductor with ethylene propylene rubber (EPR) insulation. The concentric bare copper (BC) full neutral enhances grounding and safety, making it ideal for robust underground residential distribution (URO) networks.
