Problems of industrial electrical connected air conditioning

Problems of industrial electrical connected air conditioning

Answer:

First of all, the two wires should be single-phase, one is FireWire, one is zero line. The voltage between the two wires should be 220V. The landlord tested one of the wires for 220V

Another set of wires, one with 220V and the other with 110V, is also a problem, and the key lies in testing methods. It should be measured by specific voltage test pencil.

Return again: if you use the test pencil can measure 220V, so my advice is to find a professional electrician to help you solve.

Test method for voltage is this. We will adjust the multimeter to AC voltage profile, select automatic range or a suitable range. Then, the voltage of the voltage meter stick into the hole. (this is the general with general method, the table in case your voltmeter is special, there are may not be the same)
