Hard to answer this question with out the load type and amperage. Depending on the type of load some wire feeders have to be increased by 25%. For a correct answer state what the three phase load is and its wattage or amperage.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

What size wire is required for a 220 volt at 54 amps?

For a 220 volt circuit at 54 amps, you would need a wire rated for at least 6 AWG (American Wire Gauge) size to handle the current safely. It's always recommended to consult with a licensed electrician or refer to local electrical codes for specific requirements.


What size wire for 220 volt dryer from breaker to outlet?

For a 220 volt dryer, a 10-gauge wire is typically used for the connection from the breaker to the outlet. It is important to ensure that the wire matches the amperage rating of your breaker to maintain safety and efficiency in the circuit. Consulting local electrical codes and a professional electrician is recommended for accurate specifications.


Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?

No !


What wire size for 220 volt 10 amp?

For a 220 volt, 10 amp circuit, you can use 14 gauge wire if the circuit is protected by a 15 amp breaker or fuse. However, it's always a good idea to consult local electrical codes and regulations to ensure the correct wire size for your specific situation.


What size in a 90 amp 220 volt circuit?

A 90 amp 220 volt circuit would typically require a wire size of at least 4 AWG (American Wire Gauge) for copper conductors or 2 AWG for aluminum conductors to safely handle the current without overheating. It is important to consult with a qualified electrician to ensure proper wiring size and installation according to local electrical codes.

Can you use uf 12-2 wg wire for 220 volt?

Yes, you can use UF 12-2 WG wire for a 220-volt circuit, as long as it is properly sized for the amperage of the circuit and within the voltage rating of the wire. Make sure to consult the National Electrical Code (NEC) and local codes to ensure compliance.


Is a 220 volt electrical power wire the same as a 240 volt electrical power wire?

Yes 220 & 240 are considered the same.


On a 220 volt circuit where the white wire is common how many volts would the red wire be?

In a 220 volt circuit with a common white wire, the red wire would also carry 220 volts. The white wire is the neutral wire that completes the circuit and does not have a voltage potential, while the red wire is one of the hot wires that carries the full voltage of the circuit.


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.


What size romex for 5000 watt dryer?

For a 5000 watt dryer, you should use 10-gauge (AWG) copper wire with a 30-amp circuit breaker. This corresponds to a 3-wire, 240-volt circuit with a ground wire. Make sure to consult your local electrical codes and a licensed electrician for accurate installation.


Can you use the ground conductor in a 14 AWG 2 conductor with a ground for the neutral in a 220V 15 amp circuit with less than 50ft run?

yes <<>> No, the ground wire is never to be used as a neutral. In this case if you need a 120 volt circuit from the 220 volt circuit a three wire cable (3C #14) must be installed.
