Generator transfer switch sources are different and independent. After one power supply is cut off, the second power supply will not be cut off at the same time, which can meet the supply of primary and secondary loads. Dual circuit generally refers to the end, after one line fault, another standby circuit is put into operation to supply power to the equipment. The two loops may be the same power supply or different power supply.
The Precautions For The Installation And Use Of The Load Transfer Switch Are As Follows:
1) When the switch is installed, the handle should be kept in a horizontal rotation position.
2) Because of the low on-off capability of the load transfer switch, it can not be used to break the fault current. When the motor is used for positive and negative rotation control, the power supply can only be connected after the motor completely stops turning.
3) When the load power factor is low, the contact capacity of the switch should be reduced.
The dual power transfer switch is a switch for switching the function of the main circuit and the standby circuit. When the main circuit is de-energized, the dual power switch will automatically switch to the standby circuit (usually an alternator) to ensure the normal use of the electrical appliances in the circuit.
The PKQ2 dual power transfer switch also features an isolation function that provides significant breakpoints during circuit maintenance to prevent the risk of electric shock
