A PowerCon blue‑to‑gray cable in 12‑gauge, 15' length is used to link power‑in and power‑out connections on lighting, audio, and production gear that relies on locking Neutrik‑style connectors. The blue end serves as the power‑in plug, while the gray end provides a dedicated power‑out path, with keyed housings that prevent incorrect mating. The 12‑gauge conductors offer higher current capacity and durability for demanding event or touring use, and the 15‑foot length provides flexibility for routing power between fixtures, distro points, or stage positions while keeping the run manageable and tidy.
