Engaged in industrial use to correct energy measurement is accurate

People tend to think there is no problem as long as the meter and turn electricity meter is calculating apparatus. Industrial and life are inseparable from how much power meter mcb circuit breaker . The right to engage in industrial, energy measurement is accurate. Therefore, the meter aluminum plate is inverted, electri cenergy meter worker sometimes not Circuit breaker to analyze the wiring diagram, maintenance meter wiring, only that is the voltage phase sequence is wrong, free exchange in which the three-phase voltage line two phases. Once you turn right, you think everything is normal. This is totally wrong.
