Light Switch/Electrical Outlet Combo
Can you use a 15-amp outlet on a 20-amp circuit?
According to the National Electrical Code, only a 15-amp or 20-amp electrical outlet can be installed on a 20-amp circuit. A 15-amp receptacle may also be installed on a 15-amp circuit. However, a 20-amp GFCI outlet may not be installed to a 15-amp circuit. Never overload your circuit – a circuit breaker should never exceed 80% of its amperage.
What is the difference between single pole and double pole devices?
A single pole switch is used to control a light, outlet, or another device from one location. A distinguishing feature of single pole and double pole switches are the ON and OFF symbols on the toggle switch. This feature is not found on 3-way or 4-way switches. Double pole switches are used in industrial application, and are generally rated 30 amps. The main difference between the two is that a double pole switch has 4 hot brass terminals and one ground wire. This allows you to connect the switch outlet combo to two pairs of hot wires from a 240V circuit.
What is the minimum height that electrical outlets must be from the ground or floor level?
According to the 2017 NEC, electrical outlets should be mounted on the wall no less than 15 inches from the floor. The standard height for wall outlet boxes is about 12 inches from the finished floor to the bottom of the box.
How does a light switch and outlet combo operate?
The switch/receptacle combo device is set up like a duplex outlet, but has a 15A single pole switch on one side, and a single 15A, 125V outlet on the other side. They can either be wired to work in conjunction with each other, or be connected to work independently. These outlets can be used in workshops and garages to control both a light fixture as well as a power tool.
