The answer will depend on where in the world you live and the local adopted electrical code.
In the US, generally yes, 220V branch circuits are legal. Most electric ranges, electric water heaters and house air conditioning units require 220 (actually nominal 240) volts, and are fed from a branch circuit.
There are limitations and exceptions. For instance, the NEC ( 210.6(A) ) limits the following branch circuits to 120 volts nominal:
In dwelling units, guest rooms or guest suites of hotels, motels and similar occupancies, the voltage shall not exceed 120 volts, nominal, between conductors that supply the terminals of the following: 1. Luminaires (lighting fixtures) 2. cord-and-plug connected loads 1440 volt-amperes, nominal, or less or less than 1/4hp.
NEC (2005) article 210.6 covers branch circuit voltage limitations.
What else can I help you with?
How long does current remain in a 220 volt circuit?
The current in a 220 volt circuit depends on the resistance of the load connected to it. Ohm's Law (I = V/R) states that current (I) is equal to voltage (V) divided by resistance (R). So, the current will vary based on the resistance of the circuit.
Can i use a 220 volt ac in the basement to run branch circuits for 110 volt lighting?
Yes, you can use a 220-volt circuit in the basement to run branch circuits for 110-volt lighting. You would need to install a step-down transformer near the lighting circuits to reduce the voltage from 220 to 110 volts. Make sure to adhere to electrical codes and regulations when setting up the system to ensure safety and proper functioning.
Install to 220 volt appliance at home?
To install a 220-volt appliance at home, you will need to ensure you have the correct outlet and circuit in place. Hire a qualified electrician to install the appropriate outlet, usually a NEMA 6-15 or 6-20 for 220-volt appliances. Make sure the circuit can handle the load of the appliance to prevent any electrical hazards.
Is 220 amp connected for 230 volt?
The question can't be answered - it has no meaning :)
Can you use 265 volt appliance on a 220 volt line?
Using a 265-volt appliance on a 220-volt line can be risky and may damage the appliance, cause a short circuit, or result in a safety hazard. It is recommended to use voltage converters or transformers to ensure safe operation of the appliance.
What is the recommended wire size for a 220 volt circuit according to the 220 volt wire size chart?

What is the appropriate wire size for a 220 volt 30 amp circuit?
The appropriate wire size for a 220 volt 30 amp circuit is typically 10 gauge wire.
How long does current remain in a 220 volt circuit?
The current in a 220 volt circuit depends on the resistance of the load connected to it. Ohm's Law (I = V/R) states that current (I) is equal to voltage (V) divided by resistance (R). So, the current will vary based on the resistance of the circuit.
Can you supply three 220 -240 volt 16.6 amp infrared heaters with one circuit?
Can you supply three 220 -240 volt 16.6 amp infrared heaters with one circuit?
What is the appropriate wire size for a 220 volt circuit with a 30 amp capacity?
For a 220 volt circuit with a 30 amp capacity, the appropriate wire size would be 10 gauge wire.
Can 110 volt apliance work on 220 volts circuit?
NO - that is dangerous.
Is there an adapter that will make a 110 volt refrigerator receptacle into a 220 volt?
No. You need to rewire the circuit from the electric panel.
