Factory-terminated devices and connectors mean that device installation is the same regardless of skill level of the installer. The UL-Listed connectors are keyed to ensure proper wiring installation into each extra heavy-duty receptacle. The connector simply snaps into the back of the device - no fussing with wires, stripping or tightening screws. PlugTail devices are finger safe with no exposed terminals, so taping is not required. Now device installation is a snap.
