For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
Yes, you can use 600 volt wire for a 240 volt appliance. Just make sure that the wire meets the appropriate gauge size for the current draw of the appliance to avoid overheating and ensure safety.
A 3/0 copper conductor with an insulation rating of 90 degrees C is rated at 225 amps.
Assuming you are working with 240v, you need 4/0 copper conductors.
It could if you don't get the terminals and motor wires on the correct terminals.
For a 240V 30A circuit, you would typically use a 10-gauge wire for the neutral conductor. It's important to follow the National Electrical Code (NEC) and any local regulations when determining the appropriate wire size for your specific installation to ensure safety and compliance.
