If you are running a sub-panel, consider going one size larger than necessary. It is much cheaper to buy a thicker wire now than to dig a new trench in five years. The "It worked for an hour so it's
Don’t guess the gauge: Why conductor size is the heart of your electrical system. ⚡ : The heavy-lifter for water heaters and AC units
Small wire + High current = 🔥 Correct size + Load calculation = 🔒
: Over long distances, a wire that is too thin will "steal" voltage. For a standard 120V system, the minimum voltage must stay above 108V. If the wire is undersized, an appliance at the end of the line might not even start.
