In England and Europe yes, 240 volts is the star point voltage of a 416 volt three phase four wire system. In North America no, it is not normal to have 240 volts to ground. On a single phase system that is used in homes it should only be 120 volts.
In control panels that use 240 volts as a control voltage and one side of the control transformer is taken to ground, only then would you find the 240 to ground. This connection is used to trouble shoot the control panel by allowing one of the voltage tester leads to be connected to ground while the other lead can be used to probe for voltages at terminal points.

Why does 220 volt line put out 250 volts?
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
How much voltage comes into a breaker box?
In the United States, the normal house that is being built has 220 volts alternating current to legs each one carring 110 volts ac to ground.
Why 380 volts line to line if connect line to neutral is 220 volts?
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
What is the voltage in Portugal?
The local current is 220 volts and ground connection is made by a 2 pin plug.
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
How connect a transformer 380 volt 3 pH to 220 volt mono pH?
any one of the three line to neutral is 220 volts
What is the normal voltage of house electricity in the US?
The voltage in North America can be as low as 110 and as high as 125 volts. The average is about 115 to 117 volts. <><><>><> House voltage in the US is generally 120v line to neutral and 240v line to line. It is referred to as a "120/240v single phase service." Actual voltage can be as low as 110/220 or as high as 125/250.
What is meant by 220 KV in 220 KV three phase Power Transmission line?
KV is the abbreviation for kilovolts. The prefix kilo means thousands, so 220 kv means 220 kilovolts, or 220,000 volts.
How do you connect 2 110 volts brown wires two blue wires and two ground wires in a 220 volts fuse box to converts 110 into 220 volts?
The specific colours of brown and blue suggests that this is a question from the UK or European area. On checking the IP address it shows that the question comes from Uruguay. 110 volts is not a common voltage to this area, so that 110 volts can not be converted to 220 volts because 220 volts is the common working voltage. If the question is asking about using 120 volt equipment in that country see related links below.
How do I make a 30 amp 250 volt line output only 220 volts at 30 amps?
you get a transformer...
Does your house have 440 volt line?
No houses are wired for 440 volts. In the USA, most houses are wired for 240/120 volts called single or split phase. That means each "leg" of the service is 120 volts to ground, but across the two it sums to 240 volts, since each "leg" is 180 degrees out of phase with respect to each other. When one "leg" of the service is at +120 volts, the other "leg" is its mirror image, at -120 volts. In this way, connecting across the two yields twice the voltage of either leg to ground, allowing the use of 240 volt or 120 volt appliances depending on how connected- to ground or across "legs". Most other countries with 220-240 volt appliances do not use split phase service. There is only the one phase to ground and in those countries the incoming line is 220-240 volts to ground, voltage depending on the country.
Does a 220 outlet have 2 hot wires?
Yes, a 220 outlet typically has two hot wires, one neutral wire, and one ground wire. The two hot wires each carry 110 volts, which combine to provide 220 volts for larger appliances like dryers and ranges.
