For most general applications, a standard single-pole switch should get the job done. For example, if you need a switch to operate a light or fan, a single switch works best. On the other hand, if you want to operate a device at two locations, you need a double pole switch.
Do I need a single pole or double pole switch?
Whilst a single pole socket is generally cheaper it is always preferred that customers/electricians install double pole sockets for safer isolation of the plugged in appliances.
When would you use a double pole switch?
Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. A double pole switch can be used to control light and a fan or 2 lights on separate circuits.
How do you know if a light switch is single or double pole?
Poles: A switch pole refers to the number of separate circuits that the switch controls. A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. A double-pole switch is like two separate single-pole switches that are mechanically operated by the same lever, knob, or button.
What is a single pole switch used for?
A single pole switch is used to control the light in a small closet or bathroom. Its called a single pole switch because there are two wires connected or separated by the switch mechanism. Theres also a ground wire to protect against electrical faults.
What is the difference between single pole and double pole MCB?
A single pole breaker is typically used with 120-volt circuits, 15-20 amps. They are constructed with one hot wire and one neutral wire. A double pole breaker is primarily used with a 240-volt circuit, 20-60 amps and consists of two hot wires.
Can a single pole switch control two lights?
A single light switch that controls two fixtures, such as two lights or a light and a bathroom or ceiling fan, can be converted to a double light switch that allows you to operate each fixture independently. Youll need a screwdriver, a pair of wire strippers, a double switch plate and a voltage tester.
How do you know if a switch is single pole or 3 way?
When viewed from the front, a standard single-pole toggle switch has on/off markings next to (or above and below) the toggle. A 3-way switch has no on or off markings because the toggle can turn the light on or off in either position, and this depends on the position of the other switchs toggle.
Does it matter which wire goes where on a single pole switch?
In the case of a single-pole switch, these wires are interchangeable—it doesnt make any difference which wire is attached to which screw terminal. Usually, its a simple matter of pigtailing the switchs grounding screw to the circuit grounding wires.
Can I use ground as neutral?
a ground and a neutral are both wires. unless theyre tied together with other circuits, and not a home run back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.
Can I use two single pole breakers instead of a double pole?
Can I replace a double pole breaker with two single pole breakers? Two pole breakers to one pole breaker. Youll have to return to the double-pole breaker if you decide to use the red wire again. Two single-pole breakers cant be used for a multiwire circuit.

What is the difference between a single pole and 3 way switch?
The most common household switch, a single-pole, has two terminals and simply turns power on or off. A three-way switch has three terminals; a four-way has four. You can usually replace any single-pole switch with a dimmer.
How do I know if my switch is single pole?
Single-Pole Switch Its characteristic on/off markings on the toggle arent found on other switches. However, some styles of single-pole switches (notably, rocker-style switches) do not have on/off markings. A single-pole switch has two brass-colored screw terminals that are connected to the hot, or power-source, wires.
Can you use a 3 way switch for single pole?
In order for a 3-way switch to function as a single pole, the wires need to be connected to the common and one of the traveler terminals. It will not work if the wires are connected to the two traveler terminals. 3-way switches can be converted to single pole in several configurations.
Does a single pole switch need to be grounded?
If you are replacing a switch a ground is not required, as per the above exception. However, if youre installing a switch; replacement or otherwise, into a metal box that is grounded. The switch will be ground via the devices yoke and mounting screws. So if the metal box is grounded, the switch is also grounded.
