The power receptacle on the pigtail adapter cannot be substituted and must use the Neutrik PowerCon or True1 receptacles. Per the NEC (410.151), "lighting track fittings shall not be equipped with general-purpose receptacles" (e.g. NEMA, stage pin, etc...). In addition, we cannot sell this pigtail adapter with bare ends.
