Either #6AWG copper of #4 AWG aluminum wire rated for 90 c.

These values are rated at exactly 75 amps so you still need to calculate for voltage drop, conduit fill, and ambient temperature. So as a basic rule of thumb I always step up one wire size(#4awg copper and #3 aluminum) just to be safe.

For a 75 amp circuit, use a wire gauge of at least 6 AWG for copper wire or 4 AWG for aluminum wire to ensure it can safely handle the current without overheating. It's always recommended to consult with a professional electrician to determine the appropriate wire size for your specific application.

It depend on what the load is. If it is a motor load then the size of the conductor has to be increased by 125% of the motor's full load amperage.

A #6 copper conductor with an insulation rating of 90 degrees C is rated at 75 amps. If the insulation factor is 70 degrees C then the conductor size is increased to a #4 conductor. If the insulation factor is 60 degrees C then the conductor size is increased to a #3 conductor.

Could use #4 Copper or #3 Aluminum, not taking voltage drop into consideration. You won't have to take voltage drop into the equation, unless your wire run is over 90 or 100 feet.

What size wire for 25 amp 110 volt for 75 feet?

For a 25 amp load at 110 volts over a distance of 75 feet, it is recommended to use a minimum of 10 gauge wire to ensure proper conductivity and safety. Using a wire gauge smaller than 10 may result in voltage drop and overheating of the wire.


What is the amp rating of NM wire?

The amp rating of NM (Non-Metallic) wire varies depending on the gauge of the wire. For example, a 14-gauge NM wire typically has an amp rating of 15 amps, while a 12-gauge NM wire has an amp rating of 20 amps. It is important to consult local building codes and regulations to determine the appropriate wire gauge and amp rating for specific applications.


What is the amp size of a 8 wire?

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.


Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?

No, it is not safe to use 10 gauge wire with a 30 amp breaker as the wire is not rated for that high of a current. It is important to use the correct wire gauge that matches the breaker amperage to prevent overheating and potential fire hazards. For a 30 amp breaker, you should use at least 10 gauge wire.


What type of wire for two 15 amp breakers panel at 75 feet?

For a 75-foot run on a 15 amp circuit, you would typically use 14-gauge copper wire for general household applications. This wire size is rated to safely carry the maximum current of a 15 amp circuit. Be sure to consult local electrical codes and regulations for specific requirements.

Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?

No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.


What gauge wire for a 60 amp circuit?

AWG #6 wire.

What is a wire gauge and what is it's use?

wire gauge is used to determine the size of the wire to be installed based on the amperage draw of whatever is being hooked up on the receiving end. ie 14 gauge is for a 15 amp circuit, 12 gauge is for a 20 amp circuit, 10 gauge 30 amp etc. to get specific amp draw ratings on a particular gauge of wire look at a current National Electric code book or ugly book.

Can you use 8 gauge wire with a 50 amp breaker?

No, an 8 gauge wire is typically rated for a maximum of 40 amps. It is important to match the wire gauge with the appropriate amperage to prevent overheating and potential fire hazards. In this case, you would need to use a thicker wire gauge, such as 6 gauge, for a 50 amp breaker.
