Abstract
A unique arrangement includes a duplex receptacle outlet providing two voltages. A first power wire supplying a first voltage is connected to the receptacle supplying a higher voltage. A second power wire is connected to both receptacles, and a neutral wire is connected to the receptacle supplying a lower voltage. In this manner, a standard electrical outlet need only be modified such that the receptacle has its plug interface modified to receive a standard higher voltage.
Claims16
A duplex receptacle electrical outlet comprising:
- a pair of receptacle locations, with a first of said receptacle locations being configured to receive a first type standard plug, and a second of the receptacle locations being configured to receive a second type standard plug, and said first and second receptacle locations being capable of being utilized simultaneously.
A duplex receptacle electrical outlet comprising:
- a pair of receptacle locations, with a first of said receptacle locations being configured to receive a first type standard plug, and a second of the receptacle locations being configured to receive a second type standard plug, said first and second standard plug types are for first and second voltages, respectively, said first voltage is twice said second voltage;
- a cable having at least three wires is connected to supply power to the two receptacles;
- and
- a first wire on the cable supplies a neutral path and is connected to the second receptacle, a second wire is to be powered to provide one of 110 and 120 V, and is connected to the first receptacle, and a third wire is to be powered to provide one of 110 and 120 V and is connected to both of the first and second receptacles.
The duplex receptacle electrical outlet as set forth in claim 54, wherein a fourth wire is also provided in the cable and used as a ground wire for both receptacles.
A method of forming a receptacle electrical outlet comprising the steps of:
- providing a pair of receptacle locations, with a first of said receptacle locations being configured to receive a standard plug of a first voltage, and a second of the receptacle locations being configured to receive a standard plug of a second voltage, said first receptacle providing said first voltage into said standard plug simultaneously as said second receptacle providing said second voltage to its standard plug.
A method of forming a receptacle electrical outlet comprising the steps of:
- (a) providing a pair of receptacle locations, with a first of said receptacle locations being configured to receive a standard plug of a first voltage, and a second of the receptacle locations being configured to receive a standard plug of a second voltage, said first voltage is twice said second voltage;
- (b) a cable having at least three wires is connected to supply power to the two receptacles,
- (c) a first wire on the cable supplies a neutral path and is connected to the second receptacle, a second wire is powered to provide one of 110 and 120 V, and is connected to the first receptacle, and a third wire is powered to provide one of 110 and 120 V and is connected to both of the first and second receptacles.
