Wire size for 100 amp sub panel 50 feet away
What size wire do I need for a 50 amp service 100 feet? If you run 50 amps to a sub-panel 100 feet away, the appropriate wire size is 4 AWG copper. You should also ensure that the 50 amp breaker in your main panel can handle the current load. An appropriately rated transfer switch is also essential if you’re connecting this wiring to a generator. If you have electricity, you probably have an electrical panel for it, too. Also called a load center or breaker box, it takes your main source of electricity and divides it up between the various areas that require power in your home. Here...However, you can also normally use aluminum wire instead of copper wire when connecting panels, and that can save a lot of money even though you need to use larger wire. For example, 2 AWG aluminum will get you 90A, enough for a huge subpanel, and cost (typically) close to the price of 8 AWG or even 10 AWG copper.

I want to run 100 amp service to the new building but am not sure of the size of the wire due to the distance. I've read some of the codes, but I'm overloaded with information. I've been told I could use a tandem 100 amp breaker from the main to ...A 240 volt, 30 amp circuit would require 4/3 AWG wire. 500 Feet – a 120-volt, 20 amp circuit would require 1/0 AWG wire. A 240 volt, 30 amp circuit would require 3/3 AWG wire. Keep in mind that a 3% voltage drop is minimal. If you were to use 8/2 wire for a 150 foot run to a shed on a 20 amp breaker, chances are you wouldn’t notice the drop.
Aluminum is a lot cheaper, especially for long runs, but the size of wire needed for a typical 100 amp sub panel in garage or shed may exceed what the sub panel can handle.

A double-pole 240V circuit breaker at the main service panel usually feeds your subpanel with power. The single feed circuit is also divided into several branch circuits at the subpanel. Hire an Electrician.The next step is to wire back from the subpanel to the main panel. You’ll need to attach the hot feeder wire to a new circuit breaker (in our case a 200-volt one). Once that is done, connect the neutral and ground wires from the feeder cable to the corresponding bus bars in the main panel. Lastly, snap the feeder breaker into the main panel ...…
