Yes it does because a single-pole switch interrupts only one wire which has to be the live one.
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.

Answer for USA, Canada and countries running a 60 Hertz supply service.A single pole breaker is used to supply 120 volts to a 120 volt load circuit and to protect the conductors of that circuit. This is one "hot" wire to the load and then back to the neutral. A two pole or double pole breaker is used to supply 240 volts to a 240 volt load and to protect the conductors of that circuit. This is two "hot" wires to the load without a neutral, eg. baseboard heaters, hot water tanks. The two pole breaker is also used with a neutral when the 240 volt device needs a 120 volt supply for its controls. eg. electric range, dryer.If you mean a 120 breaker with two switches, those are designed to fit an extra circuit into a full breaker panel by removing the single, installing the double, and you now have two breakers in the space of one, each for the rated amps at 120 volts on the same "leg" of the 240 supply. These are not often recommended and some local codes do not permit them to be used more than temporarily.
Triple pole and neutral supply
Triple pole and neutral supply
"Double-pole" refers to the type of switch used to disconnect the cooker from the incoming household electricity supply. Only by using a double-pole switch can the cooker's connections to both the live (or "hot") and neutral supply wires be switched on and off simultaneously.
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
the (mcb) is miniature circuit breaker SPN is Single Pole w/neutral DP is double pole TPN is tripple pole w/neutral)MCB =Miniature circuit breaker b)SPN=Single pole and neutral ( 1 terminal for live and 1 terminal for Neutral cable for wire connection. Pole refers to a power cable connection on the MCB) c)TPN=Triple Pole & Neutral (ie. altogether 4 cable input and 4 cable out from the MCB) d) DP refers to Double Pole (with no specific neutral terminal.Still one pole may be used for that. The A refers to rated Current in amperes. Also important is ( i) the rated voltages which will govern the given in Amperes.(ii) Duty it is meant for eg. lighting , motor power etc. (Motor duty for eg is A3). Also whether AC or C supply.
US NEC: The neutral line is the white wire. Coming from the pole, it is the ground wire.
4-pole changeover switch connects also the neutral wire. 3-pole changeover switch connects only the 3 live wires.
Yes it does because a single-pole switch interrupts only one wire which has to be the live one.
vertical tri pole neutral
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
No. The Arctic is the area around the North Pole, so that is where you will find Arctic foxes.
