About this item The outlet itself is rated for 20 Amps, with the left slot (neutral) shaped like a sideways letter 'T' or ''. This T-slot is only found on 20 Amp outlets. Connecting wires can be done through push-in terminals or screw terminals. For optimal safety, it is recommended to use screw terminals, where the wire is wrapped under a screw and tightened. This method is safe for both 15 Amp and 20 Amp circuits when using the appropriate wire size. The child-proof design ensures safety by preventing unwanted objects from being inserted into the outlets. Fits with a 2-gang combo electrical junction box and low-voltage mounting bracket (not included). This power outlet wall plate allows the connection of one Ethernet/coax/HDMI cable while also powering your TV on the same plate. Dimensions: 4.5 x 4.6 x 1.2 inches.
