From the above table, if we apply the 83% rule, then the minimum required conductor size must be calculated for 83% of 100 Amps i.e., 83 Amps. So, the 100 Amp Wire Size with an 83% rule is AWG 4 for Copper Conductors and AWG 2 for both Aluminum and Copper-Clad Aluminum Conductors.Step 5. Run the wires into the service panel through the cable clamp attached to the knockout. Secure the wire by tightening the cable clamp to ensure that the wires will not move. Connect the black and red wires to the 50-amp breaker and tighten the screws. Connect the neutral wire to the neutral bar and the ground to the grounding bar.

3 AWG copper wire is the 60 amp sub panel wire size if the main’s 150 feet away and assuming the voltage drop reaches as high as 30%. That’s because if we factor in the 80% rule and the 30% voltage drop, such a setup will require a wire that can handle 97.5A in reality. If the main panel’s over 200 feet away, you can use a 4 AWG copper or ...

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.

If this is a new installation, you should have an EGC (ground wire) running back to the main panel, in addition to the ground rod (4 wires total), with the neutral and ground remaining separate back to the main panel. If, however, you have 3-wire service to the garage, neutral and ground *must* be bonded in the subpanel.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.Runs don't look excessive, so 12Ga for 20A and 14 Ga for 15A should be fine for wire sizes. For a 70A breaker, #4 Cu. For 80A, #2 Al. For 100A, either #3 Cu or #1 Al.
