Can I run a 100 amp subpanel from a 100 amp panel?
Let me try and answer some of your questions. 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 you run a 100 amp sub panel off a 200 amp main panel?
Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, …
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 far can you run #2 copper wire?
Example calcuation 2 – Copper Wire, 3 Phase power
Cable run: 400 ft. 1 conductor per phase utilizing a 750 kcmil Aluminum conductor installed Direct Buried will limit the voltage drop to 2.64% or less when supplying 194 amps for 400.0 feet on a 240 volt 3 phase system.
How far can I run #8 wire?
As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop.
For 240-volt circuits:
| 14 AWG | 100 feet |
|---|---|
| 12 AWG | 120 feet |

| 8 AWG | 152 feet |
| 6 AWG | 188 feet |
What wire size do I need to go 100 feet for a 60 amp service to a workshop?
What size wire should I use for a 60 amp subpanel? You can get away with 6 AWG when you have a short run of wire, however, due to voltage drop, if you ever decide you want to go more than 100 feet then a 4 AWG is the size you should choose.
What gauge wire do I need?
The rule of thumb that techs will usually go by is that for a 30 amp circuit breaker, 10-gauge wire is the right one to go with. For a 40 amp, you need an 8-gauge wire. For a 20 amp, you will need a 12-gauge wire. For 60 amp, the correct wire size is 4.
