100 amp sub panel ground wire size.

But 75 would be enough so it's best to jump up to 90 or 100. 75a = 2 awg wire with 2.56% voltage drop this would also handle 90 amps to go up to 100 amp 1 awg wire would be needed. With older panels finding anything larger than is doubtful. With max loads listed #2 and a 90 amp breaker would give additional room. - Ed Beal.When it comes to electrical installations and appliances, safety should always be the top priority. One critical aspect of ensuring safety is choosing the right wire size for the a...The size of the ground wire for a 100 amp service depends on the type of wiring used and the distance between the electrical service panel and the grounding electrode. It is best to consult a licensed electrician to determine the appropriate size.4 AWG copper ground wire for 200 amp service (at short distances). 0 AWG aluminum ground wire for 200 amp service (at short distances). Now, this is relevant is the hot wire is short. If you need a 200 amp service 50 feet, 100 feet, 150 feet, or 200 feet away (Example: 200 amp sub-panel 100 feet away), you also need to account for voltage drop.

Wire for conduit vs UF bury cable may be cheaper. Conduit is 18" burial vs. 24" burial for UF cable - another 6" at the bottom of a long trench is a lot of extra work.42.4 mm2. 1 AWG wire amps (ampacity at 75°C): 130 amps. 1 gauge wire is the first 'non-negative or 0' wire gauge. 1 gauge wire diameter is 7.348 mm and it has a 42.4 mm2 (1 AWG to mm2) cross-section or area. Given the 42.4 mm2 thickness, the 1 AWG copper wire has a current-carrying ampacity of 130 amps at 75°C.

To feed a 100amp sub panel that is 200 feet away, you will need at least a 1 AWG copper wire or simply #3 copper wire. Alternatively, you can use 2/0 aluminum wires. These two wire sizes are enough to carry 100 amp throughout that distance.Choosing the right wire size helps ensure your electrical system runs efficiently and safely, preventing potential hazards like overheating or electrical fires. Here’s what you need to know about selecting the correct wire size for a 100-amp service panel. Wire Size for 100-Amp Service. Most 100-amp service panels require #2 AWG wire.

It's best to use a 3 AWG copper or 1 AWG aluminum and a 1 ½ inch conduit for it (or even a bit larger to make wire pulling easy). With a single-phase, you'll need at least 3 wires.In this case, instead of using a 2/0 copper wire, you should use 300 kcmil copper with only a 2.78% voltage drop. This suggested size wire for a 200 amp panel will work for both single-phase and three-phase installations. On the other hand, if you are tight on budget, you can use 500 kcmil aluminum.

For a 100 amp sub panel that is 200 ft from the main, it is recommended to use 4 AWG copper wire or 2 AWG aluminum wire. These larger sizes of wire can carry more electricity and reduce the amount of voltage drop on the circuit. Additionally, they are strong enough to handle longer distances and still provide enough current for the breaker.

But if the sub-panel is located in a detached building, let us say the garage, then you also need to "ground the panel" by running a wire from its ground bar to planet Earth (e.g., to a ground rod or two). That wire would be the GEC that Bob mentioned, and it is sized per 250.66.
