The live pole carries the supply voltage and is usually colored brown or red. The neutral pole completes the circuit and is typically colored blue or black. Using a voltage detector or a multimeter set to AC voltage mode, you can identify the live wire by measuring the voltage between each wire and the ground, as the live wire will show a voltage level.
What else can I help you with?
Does it matter if the neutral and live wire swop places?
Yes it does because a single-pole switch interrupts only one wire which has to be the live one.
Where does the neutral wire go on a single pole switch?
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
What is the purpose of a double pole switch for immersion heater?
In North America both legs of the 240 volt supply are "hot" to ground. A two pole switch is used to break both legs from the supply. If only a single pole switch is used one leg will open and the tank would not operate but if you were depending on the switch to isolate the supply it could be dangerous. The other leg could lead to a shock if you touched the unswitched leg to ground while working on the tank.
What is the difference between a 2 pole and single pole breaker?
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.
What is the kingdom for penguins?
they live in the north pole they live in the north pole
What is tpn supply?
Triple pole and neutral supply
What is TPN power supply?
Triple pole and neutral supply
What does double pole mean on a cooker control unit?
"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.
On which line is the switch of electrical appliance connected?
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.
What is the definition of SPN MCB?
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.
How do you find neutral line among distribution lines?
US NEC: The neutral line is the white wire. Coming from the pole, it is the ground wire.
What is the difference between 4-pole changeover switch and 3-pole changeover switch?
4-pole changeover switch connects also the neutral wire. 3-pole changeover switch connects only the 3 live wires.
Does it matter if the neutral and live wire swop places?
Yes it does because a single-pole switch interrupts only one wire which has to be the live one.
What is meaning for TPN isolator and SPN isolator?
TPN (Triple Pole and Neutral) isolator is an electrical switch used to disconnect three-phase electrical circuits, ensuring that all three phases and the neutral are isolated for safety during maintenance or servicing. SPN (Single Pole and Neutral) isolator, on the other hand, is used for single-phase circuits, allowing isolation of the live wire and the neutral wire. Both types of isolators are crucial for ensuring safety by preventing accidental energization of circuits during work.
What is vtpn?
vertical tri pole neutral
Where does the neutral wire go on a single pole switch?
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
What is the difference between single pole mcb and double pole mcb?
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.
