    powerCON is an electrical connector manufactured by Neutrik for connecting mains power to equipment in a small space. It looks and works similarly to the Speakon connector, with the line connector inserted in the chassis connector and twisted to make contact and lock. Both line and chassis connectors are fully insulated even when disconnected.
