Why does my AC unit have a light switch?
The furnace or air handler (indoor unit of an air conditioner) is required to have a way to disconnect the electricity to it within sight, so that a service technician can safely service the system without someone in another room inadvertently turning the power back on at the electric panel.
How does an AC light switch work?
The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.
How do you find the constant power from a light switch?
It may be power supplied to one of the light boxes, and then a “switch loop” down to the switch – in which case you can tap continuous power at the light fixture where power is supplied on the feed side of the “switch loop.” If that does not happen to the fixture you’d like to connect to, you’ll need to run a non- …
Can I take power from a light switch?

How do you know if a light switch is wired?
Inside an outlet’s electrical box, the black (hot) wire should be connected to the brass-colored terminal on the outlet. The white (neutral) wire should be connected to the silver-colored terminal. If these connections are backward, the polarity is wrong.
Does a light switch break the circuit?
Current flows through a switch to the load, such as a ceiling light. When you flip the switch off, it breaks the circuit and interrupts the flow of electricity. A basic light switch has two terminals and sometimes a ground terminal.
Can you wire an outlet from a light switch?
Adding an electrical outlet next to an existing light switch is easy, as long as there is a neutral wire in the box.

Can I wire an outlet from a light?
If you want to continue having a light in the fixture but need a receptacle as well, you can install a lamp-holder-to-outlet adapter instead.

How do you separate a light switch from an outlet?
Your choices are to run a separate line from the electrical box to the outlet, or run a separate line from the hot lines in the light switch box to the outlet. One tip is to make a little drawing of what is connected to what as you take things apart, even tagging wires with labels if you need to.
What is split receptacle wiring?
A split outlet is a duplex outlet, or receptacle, typically with one half of the outlet that has power all the time and one half that is controlled by a switch. If you have a bedroom that has no overhead light, chances are at least one of the receptacles in the room is a split receptacle.
Are switched outlets different from regular outlets?
A half-hot (or switched) outlet is a duplex outlet that has one half permanently “on,” or ready to provide electricity, while the other half can be turned off and on via an ordinary wall switch.
How do I remove an electrical outlet?
You simply need to convert the outlet into a junction box :
- Flip the circuit breaker off.
- Unscrew the hots, neutrals, and ground from the outlet and remove the outlet.
- Splice the hot, neutral, and ground from both sides (charge and load) and put wire nuts on.
- Cover the box with a junction box lid.
- Flip the circuit back on.
What do you do with an electrical outlet when removing a wall?
If the outlet is to be removed permanently, remove the electrical box and install drywall over the exposed area. Electrical boxes are attached to studs with nails, so you will have to pry the nails away. Many times, the box, usually plastic, ends up breaking. This is OK if you do not plan on reusing it.
