If you currently use the typical Pin & Sleeve type Plug and Receptacle to connect a power source to your equipment; you likely often consider these safety risks.
- Disconnection of plug while energized could result in an arc flash event
- Potential for exposure of live conductors when the plug is removed from the receptacle
- Connection while energized may weld contacts together damaging plug and receptacle
- Mechanical interlocking may fail resulting in an energized plug and receptacle
- Verification of zero energy requires testing of the requires disconnect switch

One of the primary keys is in the Safety Shutter on the Receptacle. Shutter automatically closes before the plug can be removed. Eliminates unintended access to live parts and arc flash. Shutter can only be opened by an electrically compatible plug.
