Ran 22AWG on a 300 foot garage run last month instead of 18AWG, and the keypad brownout calls stopped cold
Two service trips later I finally admit the voltage drop math on the box was right the first time, so what gauge are you all pulling for detached shops past 250 feet?
Why do we always trust the box math only after the third trip? Same thing happens with oil changes and dentist visits, the cheap fix always costs more later.
