Single-phase 220V device on a two-phase 220V network: • Can I CONNECT a 220V device... The use of air conditioning is quite common these days, especially in commercial environments. Three-phase air conditioning is used in large rooms, auditoriums or even in refrigeration plants due to its greater power. The sizing of the circuit breaker and cable for three-phase air conditioning must follow some steps. But after all, which circuit breaker to use for air conditioning and which cable is indicated to connect it, how to size the circuit breaker and cable for three-phase air conditioning. The use of a three-phase network is quite common in commercial environments. To size the circuit breaker and cable for the air conditioning, we must basically know what the supply voltage of this device will be and what electrical current it will require from the network. Normally, the air conditioning is indicated in BTU, so we must convert this refrigeration power to electrical power, from there, calculate the electrical current of the air conditioner. We must also pay attention to the voltage drop in the cables if the circuit is very long, so we must also make calculations for the voltage drop. To size the circuit breaker and cable for a three-phase air conditioner, we must use a three-pole circuit breaker to protect the cables of the three phases and this circuit breaker must also be at least curve C because the device is an inductive load due to its three-phase motor. So guys, let's learn more about how to size the circuit breaker and cable for a three-phase air conditioner in this video.
