This is a Stage Plus premade 0.3 metre power link cable (SP-CABH731HP3FHP3G.3) with an Amphenol HP-3-F connector on one end and an Amphenol HP-3-FG connector on the other, on H07-grade 3 x 1.5 mm² flexible cable. Stage Plus is AV Distribution's South African house brand, and it assembles premade cables in-house for stages, venues, rental companies and installers who want a ready-to-use, tested cable. Amphenol's HP series are latching three-pole (live, neutral and earth) AC power cable connectors rated at 25 A / 250 V AC, keyed and colour coded: the blue HP-3-F is the power-in connector and the grey HP-3-FG is the power-out connector. They are Amphenol's equivalent of the widely used Neutrik powerCON NAC3FCA and NAC3FCB. A short 0.3 m lead like this is typically used to daisy-chain mains power from one powered speaker, amplifier or lighting fixture to the next in a rack or on a truss. Important: HP connectors must not be connected or disconnected under load.
