Web3 aug. 2024 · To calculate the total load, you would multiply 20 x 208, which equals 4160. That means the total load on the 3 phase panel is 4160 watts. Keep in mind that the total load should never exceed the rated capacity of the 3 phase panel. If it does, that means the panel is being overloaded and could result in serious damage or even a fire hazard.
