im wiring a garage and have a 100 amp main breaker and a 125 amp fuse box i need cable to go from pole to garage

Asked by: willy
If I understand properly, you need a wire or cable capable of 100 Amps (it is protected by a 100A breaker at your main panel). You can use THHN conductors for this application but they will need to be installed in conduit, both inside and outside. For a 100 Amp circuit, you would need at least size 3 AWG CU THHN conductors. For the ampacities of CU THHN conductors, please see the catalog sheet at: Use the 75°C column for the allowable ampacity. If you really need 125 Amps, use size 1 AWG conductors.
