- Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
