Installation of air conditioning problem: voltage regulator can solve the problem of too thin wire

First check your store power line is how thick, if it is a 4-square copper-core wire there is no problem, indicating that the voltage is too low for the sake of the air conditioning operating voltage range between 187-242 volts, if you go beyond this range, it is necessary to buy a voltage regulator to use the voltage regulator's power should be the air conditioning of the total power of the three times as appropriate. If the power cord is too thin, with a voltage regulator is not possible, the power cord will heat up and cause accidents. If it is 2.5 square copper wire, just enough for 2 horsepower air conditioning refrigeration use, but can not be given to other larger power appliances used.
