The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)

What size wire do I need for a 100 amp underground 300 ft run?

for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, …

How many amps is #4 wire good for?

How many amps can a 4 gauge wire handle? It has a rated ampacity of 85 amps at 75°C. This means that, for average use, the 4 gauge wire can handle up to 85 amps safely.

How much load can a 100 amp panel handle?

As stated, the 100 Amp service x 240 Volts can supply a maximum of 24,000 Watts. If an 80 percent safety factor is used for your main breakers, then you would have a maximum safe continuous load of 19,200 Watts.

Can a 100 amp main panel feed a 100 amp sub panel?

First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.

Can a main panel be used as a subpanel?

There’s no problem with having a main breaker in a subpanel. It’s required if your panel is in a separate building and has more than six breakers, but there’s nothing prohibiting it in any other case.

How many amps is #6 wire good for?

Can you feed a 100 amp sub panel with a 50 amp breaker?

As the panel is rated at 100 amps the 50 amp breaker can be used for any circuit in the panel. However, everything on the circuit would then need to be rated for 50 amps or better. Few circuits require 50 amps and most of the equipment in your house is not rated for it.

What gauge wire do I need?

To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.

What does URD stand for in electrical wire?

Underground residential distribution wire (URD) is a specialty aluminum wire intended for use in residential construction and light to medium duty commercial applications.

What is the 6 throw rule?

The “six breaker throw rule” was a requirement in the National Electrical Code that a service must have have a main disconnect that shuts off all power and it cannot take more than six switch throws to do it, and the main disconnect(s) also must be clearly marked, as in the photo above.

How much can you run off 60 amps?

Newer homes have 100 to 200. The amount of power that each circuit can handle is the number of volts (usually 120) times the number of amps. Therefore, that 60 amp circuit can handle 7200 watts.

What size breaker do I need to run a sub panel?

Based on your question, since you will be having a subpanel, you want the breaker feeding the subpanel to be sized for the subpanel or slightly smaller. So if you purchase and install a 200A subpanel, then the breaker should be 200A. If you use a 125A subpanel, then use a 125A breaker.
