The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The 120 voltage is already there to use in a residential system. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and as you know from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.
What else can I help you with?
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
What are the two most popular operating voltages for residences?
120v and 240v
Can you use a 240V disconnect switch for a 120V AC?
Yes and you will have a spare terminal for future use
Does an air conditioner need special voltage?
Yes, air conditioners often require a specific voltage for optimal performance. Most residential units operate on standard voltages like 120V or 240V, depending on their size and type. It's essential to check the manufacturer's specifications to ensure that your electrical system can support the voltage required for the air conditioner you intend to install. Using the wrong voltage can lead to inefficiency or damage to the unit.
What does 240 mean?
240 refers to the voltage used in an electrical system. The US uses 120V/240V, while the UK uses just 240V.
Can 240V washer run on 120V outlet?
No.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
How many 120v lines enter a building from the power company?
Typically, a building receives two 120V lines from the power company, creating a split-phase system. These two lines are used to create a 240V supply for larger appliances and equipment within the building.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
What would cause light sockets to read 130V in a 240V system when the light switch is off?
More than likely, your 240V system has branches that supply a standard household 120V to things like lighting outlets. Most light bulbs in the US run on 120V so this is probably a convenience feature. Otherwise you would have to go to a specialty store and buy 240V bulbs.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
Can I use 120v 10a 1250 w cable for projector 110-240v power in India?
You can use 120v 10a 125w cable projectors 110-240v power in India.
How to convert 120v to 240v for electrical appliances?
To convert 120v to 240v for electrical appliances, you can use a step-up transformer. This device increases the voltage from 120v to 240v, allowing you to safely power appliances that require the higher voltage. Make sure to follow all safety precautions and consult a professional if needed.
How can voltage increase to 240V when only 120V is coming from the breaker box?
This could occur if the 120V supply is split-phase, where two 120V lines are 180 degrees out of phase with each other. When measuring from one of these lines to the other, you would see 240V. This is a common setup in residential electrical systems in the United States.
You have 120v photo flash lights - how do you use them with 240v in Oz?
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
