Best to get quotes from two or three licensed electricians for the installation of the necessary extra fuses, breakers, etc., testing and commissioning (= handing over to customer to use) of a 120V panel for as many circuits as you want. Though the question does not specifically ask about DIY ("Doing It Yourself"), if you are not a licensed electrical technician you should not even think of doing this kind of work as a DIY project because 3 phase 240V power supplies can kill you if you don't know exactly what you are doing. Depending on your local wiring codes and regulations, it may be illegal to attempt to do such work if you are an unlicensed person.
What else can I help you with?
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?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
Can an American 240V dual phase dryer be converted to work in Korea with 240V single phase power?
you could possibly design a fix for it but it would be a lot of trouble. the American dryer has internal components that run off 110v and that 110v is available from the three wire 220v circuit in the typical usa residence. this is because of the third wire, the neutral. the Korean 220 would be 2 wire. you would have to go inside the dryer, add a 220/110 transformer and rewire the dryer so that the 110v loads come off that transformer. it would then no longer be ul listed and would have to be evaluated by the authority having jurisdiction in Korea and back here in the usa.
Will a 240v 3 phase welder run better than 240v 1 phase?
Yes, because you will be able to maintain current flow between phases.
What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
What is ac supply in America?
The most common voltage supply to homes is single phase 120V / 240V. In the states for industries, 3 phase 480 Wye 277. In Canadian industries, 3 phase 600 Wye 347 volts.
How do you convert a 240v drill to 110v?
One word: KABOOM.
Can 240v coil contactor be connected to 110v supply?
no
Can 240v tools be converted to 110v?
No, it is not recommended to convert 240V tools to operate on 110V. The internal components of the tool are designed for specific voltage requirements, and altering them can damage the tool or pose safety risks. It is best to use tools with the voltage they are designed for.
IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.
240v box outside for a hot tub you need a 110v receptacle Can you wire it off the 240v box?
Using a box that is hire voltage than what you need can cause a short, and even a fire. So using a 240V box, when all you need is a 110v receptacle, wouldn't be a good idea.
Does a hot point dryer made in 96 or 97 come with a 110v cord?
All non-commercial dryers that I am aware of (in the US) require 240V single-phase power. Some large commercial dryers require 3-phase power.
What is the difference between 220v and 240v electrical systems?
The main difference between a 220v and 240v electrical system is the voltage level. A 220v system typically refers to a split-phase system where the voltage is divided into two 110v legs, while a 240v system usually refers to a single-phase system with a higher voltage level. In practical terms, the difference is minimal and most appliances and devices can work interchangeably on both systems.
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.
Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No

How do you convert from 480 volt to 220 volt or 110 volt?
AC voltage conversions are usually done with transformers. Most commonly, a 3 phase 277/480v system is transformed to a 3 phase 120/208v system. You can, however transform to anything you like with the proper transformer. If you are trying to convert 480v single phase to 240v single phase, such as for home use, then ask for that type transformer. It would use only 2 phases of the 3 phase system. Using 2 phases is called single phase and there are reasons for this that are beyond the scope of this answer. 220v and 110v are field measurements of what is considered 240v and 120v when ordering equipment or applying code.
Can you rewire a 240v lamp light fitting or small appliance to 110v and if so how?
It is not recommended to rewire a 240v lamp light fitting or appliance to operate on 110v. This can be dangerous and may lead to overheating, electrical fires, or damage to the device. It is safer and more practical to use a voltage converter or purchase a new device designed to work with 110v.
