If you want to switch a 240-volt circuit, you must interrupt both hot wires at the same time. Thats why you need a double-pole switch, which is technically one that controls two circuits.
Why would you use a double pole switch?
Double pole light switches, also known as a four-way switch, are two single pole switches put together. 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.
Do I need a single 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.
Can I replace a double pole socket with a single pole?
Double pole, yes. Definitely. For the benefit of the original poster, sigle pole isolates only the live wire, the neutral stays connected. That means that even when switched off at the plug, the neutral is still connected in the appliance.
Is a double pole switch the same as a 3 way switch?
A double-pole switch allows you to control two separate circuits using the same switch, while a three-way switch allows you to control a single circuit from two different locations. A double-pole three-way switch is able to integrate both of these functions into one.
Can you split a 2 pole breaker?
QUESTION: If I split-wire a receptacle by breaking off the tab provided on the receptacle, do I have to use a two-pole breaker to feed this receptacle? The answer is a qualified yes.
What is 2 way switch?
The 2 way switch acts as 2 switches that can control a single appliance. This is a 2 switch for a single appliance. The two-way switches are generally used for staircase case lightning and other lightning systems where we want to take control of appliances from two different locations.

What does 2 pole switch mean?
A double pole single throw switch controls two circuits (poles) and has 2 states an “on” (closed) state and an “off” (open) state. A double pole single throw has four terminals in total, two inputs and two outputs which are all controlled by the same switch.
What does a double pole switch mean?
A double pole single throw switch controls two circuits (poles) and has 2 states an “on” (closed) state and an “off” (open) state. A double pole single throw has four terminals in total, two inputs and two outputs which are all controlled by the same switch.
What is single and double pole switch?
A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. A single-throw switch is a simple on/off switch that connects or disconnects two terminals. When the switch is closed, the two terminals are connected and current flows between them.
How many wires can be in a single pole switch?
two wires 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.
Do I need 2/3 way smart switches?
When you have two switches in a 3-Way situation, both need to communicate with each other so each knows the on/off status. So to answer your question: Yes, you need to replace both switches. Just be sure the smart switch supports a 3-Way companion switch like the HS210 Kit.
Is a double pole breaker double the amps?
Since each leg of 240 volt circuit offers 120 volt potential to ground, then youre getting two legs of out-of-phase 120 volt when you use double breaker, and doing so doubles the voltage and doubles the watts (power), it does not halve the amps. And a 15 amp double breaker would be 7.5 amps on each leg.
What size wire do I need for a double pole 30 amp breaker?
In the breaker panel its hooked up to a 30-amp double pole breaker with #12 wire. Inspector notes that #10 wire should be used for 30-amp circuits so that the wire does not melt before the breaker can do its job in an over-current situation.
What is the difference between a 2 way and 1 way light switch?
1 way is an on/off switch and means theres only one place you can turn your light on or off. This is the most common kind of switch found in most homes. Most 2 way switches can also be used as a 1 way on/off switch. 2 way means theres another switch controlling the same light.
When should you use a 2 way switch?
You would use a two way light switch when you have two switches controlling one light, for instance in a hallway, where you have a switch at both ends of the hallway that controls the hallway light. You are able to switch the light on and off from either end of the hallway.
How does a 2 pole switch work?
A double pole single throw switch controls two circuits (poles) and has 2 states an “on” (closed) state and an “off” (open) state. A double pole single throw has four terminals in total, two inputs and two outputs which are all controlled by the same switch.
Does a single pole switch need a neutral?
Most single-pole switches also include a ground terminal for connecting the circuits ground wire. As a general rule, neutral (usually white) wires are not connected to switches. If two neutrals are present in the box, these wires typically are joined so that they continue through the box without touching the switch.
Can I use a 3 pole switch for single pole?
To convert a 3-way switch to single pole, one of the traveler wires is removed from the switch. 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.
