HOW TO CALCULATE BREAKER SIZE, WIRE SIZE AND WATTAGES The chart below will help you determine fuse or breaker size and the necessary wire size to service various wattage loads. To protect against material failures, the National Electric Code requires that most materials be de-rated 20%. This means that only an 80% load factor may be used when figuring electrical material needs and is …...
