What size conductor is needed to carry 25 amps 120 volt AC over 400 feet?

A #4 copper conductor will limit the voltage drop to 3% or less when supplying 25 amps for 400 feet on a 120 volt system.


What size ground wire for a 400 amp panel in Quebec?

This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.


What gauge wire will you need for a 400 watt amp?

To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.


What size conductors are needed to run a 400 foot residential underground electric service?

Need to know what size service is going to be installed at the end of the run.


What size ground wire is needed for 400 amp service entrance?

For a 400 amp service entrance, a grounding conductor of at least 3/0 AWG (American Wire Gauge) copper or 250 kcal (thousand circular mils) aluminum is required, in compliance with electrical codes and regulations. However, specific requirements may vary based on local codes and the specific conditions of the installation, so it's important to consult with a qualified electrician or refer to the applicable building codes for precise guidance.

Is number 3 copper ground conductor a common conductor size?

Answer for USA, Canada and countries running a 60 Hertz supply service.CEC states that a #3 bare copper conductor is a common grounding conductor size for a 200 amp service panel and it is the minium size for service raceway and service equipment of 400 amps.


If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?

For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.

What size power cable is needed for 30KW 440V 3phase 50Hz induction motor?

Use this formula to find amperage when kW is shown. Amps = kW x 1000/1.73 x Volts x pf. Use a power factor of .85 for the formula. Once the current is calculated re-ask the question for cable size for the calculated current.


What information can I find in the 400 amp wire size chart?

In a 400 amp wire size chart, you can find information about the appropriate wire size to use for a 400 amp electrical circuit. This includes details such as the gauge of the wire, the maximum current capacity it can handle, and the type of insulation required for safety and efficiency.

How can you calculate the capacity in megawatts of a 400 kv power line?

To calculate the capacity in megawatts of a 400 kV power line, you need to consider the current carrying capacity of the line. This is typically based on factors such as conductor size, ambient temperature, and the type of insulation used. Once you have the current carrying capacity, you can use the formula P = V x I to calculate the power capacity in megawatts, where P is power in MW, V is voltage in kV (400 kV in this case), and I is current in amperes.
