Current causes the voltage regulator fuse or circuit breaker tripped

received the regulator input distribution panel, and in the interests of the users switchboard placement rate instrument power fuse protection to ensure safe use of electricity.
electrical
mcb circuit breaker to the power supply to the output terminals of the instrument, pay attention to the rated input voltage electrical appliances should be consistent with the output of the regulator, do not pick the wrong.
first open the regulator's power switch, indicator lights. Observe the voltmeter indication is normal. Output voltage is normal, then turn on the power switch electrical equipment, the regulator that is able to automatically adjust the voltage, the normal power supply.
when unused for
air circuit breaker of electrical equipment, turn off the power switch on electrical equipment in order to reduce power consumption and prolong the life of the regulator
regulator must not overload use. Mains voltage is low, the output capacity is reduced, the regulator load should be reduced accordingly.
elected appliances are 
circuit breakers, air conditioners, pumps and other equipment with the motor running, you should choose more than three times the capacity of the regulator to prevent equipment starting current exceeds the regulator fuse current or overcurrent protection circuit breaker current to the regulator blown fuse or circuit breaker tripped or pressure drop is too large to work.
wire connected with the regulator should have sufficient load surface and prevents heat and pressure drop. Capacity 2KVA above the regulator uses terminals should be used in a single copper wire, and try to tighten the terminal screws to prevent the junction of heat.
either single-phase or three-phase voltage regulator, connect all the input and output lines, you should first turn off the power switch on the load, and then open the regulator, check the output voltage is normal, then turn the power switch on the load.
