Thereof, what size wire do I need for a 225 amp service?
With 4 - 4/0s and 4 AWG (the required EGC for 225 amp feeder) you will be just a touch over.
One may also ask, what size wire do you use for a 100 amp service? When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
Likewise, people ask, how do you calculate wire size?
Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. Multiply the cable's length by its material's resistivity.
Will 8 gauge wire carry 50 amps?
8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable. David, if that cable is NM (Romex) then it actually cannot carry 50 amps.
