I purchased a Hubbell "USB Dual Port Charger with 15A Duplex Receptacle" from Lowes to replace the duplex receptacle on my kitchen island.
I first opened the circuit labelled for the island. The breaker takes two slots. I removed the existing receptacle and noticed that the brass screws had a black and red wire. The bridge between the screws was not broken.
I connected the new USB charging receptacle as: white wire to silver screw, bare to green screw, and the black and red wires to the brass screw. I put everything back together.
When I closed the circuit the fuse blew as well as tripping the mains to the house. I took the receptacle out of the metal gang box to ensure that it wasn't touching. I verified the connections as stated above. With the receptacle hanging outside of the gang box I closed the breaker only to have it and the mains trip.
I reconnected the old simple receptacle and closed the breaker with no problems. I tried with just the black wire in the new receptacle and it worked! But now I can't connect the new receptacle with this new red wire.
I researched the uses of the red wire however none of them seem to apply to my kitchen. The fuse box lists the island as the only part to control and nothing else in the kitchen turned off when I opened the circuit. There is only one receptacle on the island and no other electrical items including lights.
Why would the kitchen island of only one receptacle require both black and red? why would this USB charger receptacle be so sensitive to two hot wires? why would this single outlet require such a large breaker switch?
And finally... is there anything I can do so that I can install this receptacle?
