#8 Wire for a 40 amp circuit...

<<>>

A three conductor#6 copper cable will limit the voltage drop to 3% or less when supplying 40 amps for 150 feet on a 240 volt system. Using a three wire you can put each 20 amp breaker on each "hot" wire and use a common neutral.

What size service cable for 100 amp main panel 100 feet away?

For a 100 amp main panel located 100 feet away, it is recommended to use a 2/0 copper or 4/0 aluminum service cable to ensure proper voltage drop and capacity for the distance. Consult with a licensed electrician to determine the specific requirements based on local codes and conditions.


What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?

If what you state in this question is accurate this is an illegal installation. A 100 amp service can not have any equipment connected to it less that that of the service size. The 60 amp main panel must be a 100 amp panel to be a legal installation.


How do you wire a circuit panel?

This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.


Is a 6 gauge 4 conductor wire still used to install a 240V 50A hot tub more than 50 ft away from the panel?

Yes, a 6 gauge 4 conductor wire is suitable for installing a 240V 50A hot tub more than 50 ft away from the main panel. The heavier gauge wire is necessary to minimize voltage drop over longer distances and ensure the proper power supply for the hot tub. Be sure to follow local electrical codes and consult with a professional electrician for a safe installation.


What wire size for 100 amp sub panel 250 ft from main panel?

For a 100 amp sub panel located 250 ft from the main panel, you would typically need to use 3/0 aluminum wire or 2/0 copper wire to ensure efficient power transmission and voltage drop within acceptable limits. It is recommended to consult with a licensed electrician to ensure the appropriate wire size and materials are used for your specific setup.

What are the key differences between a sub panel and a main panel in an electrical system?

The main panel is the primary source of power distribution in a building, while a sub panel is a secondary panel that receives power from the main panel. The main panel is typically larger and has a higher amperage capacity, while a sub panel is smaller and has a lower capacity. The main panel is usually located near the utility meter, while a sub panel can be placed in a different area of the building.
