you will need wiring that is at least 10 amp rated wire or higher. If you really needed to ask you might want to call an electrician Electrician here, be the pump 120 volts or 240 volts a #14 wire will handle the situation. Longer runs of 75 feet you should go to a #12 wire to compensate for voltage drop. The pump should be on its own separate circuit with a 15 amp breaker. A two pole 15 amp breaker if the pump is 240 volts.
3/0 gauge
Use 8 gauge wire.
2 AWG.
AWG #6
At the service entrance you will need AWG 1/0 gauge.
It is not recommended to straight wire a sump pump to the breaker box without a dedicated circuit and proper wiring. This can cause safety hazards such as overheating, electrical fires, and damage to the pump. It is always best to consult a licensed electrician for proper installation.
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.
3/0 gauge
Use 8 gauge wire.
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
The recommended well pump wire size for efficient and safe operation of the pump system is typically 12-gauge wire. This size of wire is commonly used to ensure proper power supply and prevent overheating or damage to the pump.
4 gauge
The guage of wire for 20 amps is #12 copper.
AWG #6
2 AWG.
The recommended gauge of wire to use for a 12 or 14 gauge wire is typically 10 gauge wire.
At the service entrance you will need AWG 1/0 gauge.
