∙ 10y agoFor a 70 amp load at 250 ft, you would typically need a 4 AWG copper wire to minimize voltage drop and ensure safety. It is always a good idea to consult local electrical codes and regulations to ensure compliance and safety.
You will need to use #8 wire.
For a 250 amp load, a cable size of at least 3/0 AWG (American Wire Gauge) or 70mm^2 is recommended. For a 160 amp load, a cable size of at least 1/0 AWG (American Wire Gauge) or 50mm^2 is recommended. It is important to consult local electrical codes and regulations to ensure compliance.
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.
#10 cable is no good for 120 amps, you need #2 cable, and it can be used at a distance of 250 ft.
If you use 250 or 300 MCM wire you will need a 2 1/2" weather head. If you use 300 MCM wire then you will need a 3" weather head.
You will need to use #8 wire.
8 AWG is typical.
For a 42 amp circuit, you should use at least a 8-gauge wire to ensure it can handle the current safely and prevent overheating. It's always best to consult the National Electrical Code (NEC) or a licensed electrician for specific wiring requirements to ensure compliance with local regulations.
2AWG.
A 200 amp service panel with a 60 amp sub-panel.
2 or 4
You will need AWG #3 if it is a short run.
AWG 2/0 copper wire.
Re Question with the voltage that you will be using.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
