Can you connect two air conditioner on single phase power supply?

US NEC:
You can connect two air conditioners on a single phase power supply, but...
The correct question is probably, "Can you connect two air conditioners to a single distribution circuit?". The answer is no - any substantial load requires its own distribution circuit.

∙ 11y agoYou don't say what the wattage or amperage of the AC units are, so it's impossible to say but I'm guessing that the answer is no. It would be extremely unwise to plug 2 AC units in to a standard household outlet in the US as this would be a huge fire hazard. I'm guessing that it would be the same or worse in the EU.

∙ 14y agoThe only connection to be made in the meter box is the incoming wires from the utility company and the wires going out to the main disconnect in the distribution panel. These wires have no fusing in them except for the primary fuse on the step down distribution transformer. These fuses can be over sized up to 600 percent of what they need to be. This is to stop needless tripping and since the utility company is not governed by the electrical code they are free to do it. The loophole that allows this is the fact that they are on call 24/7 and if anything goes wrong they will repair it. Now back to the meter connection. If the air conditioner connection shorted out in the meter base the short could draw up to 10,000 amps, depending on the internal impedance of the transformer, before the primary fuse opens up. This would create a lot of heat and burning would probably occur. Use the proper size fusing on the feed from the distribution panel to the air conditioner.

How can you connect single phase generator in three phase supply system in house lighting system?
First house lighting systems are single phase not three phase. To connect a generator to the house lighting system for emergency power, it would take an electrician to do the job properly. The biggest concern would be to isolate the rest of the service from the main distribution supply service and then isolate the rest of the distribution panel loads from the lighting loads.
How do you connect 3 phase inverter to single phase supply?
It depends on the 3 phase inverter. If it is a 3 phase input then you will first need to get a single phase to 3 phase converter to simulate a 3 phase supply, if that is what this particular inverter is intended for then you will have a label saying 230v primary with a L & N connection point, and the output will be labelled as secondary, giving you the inverted power rating. This is a very expensive way of running machinery as the inverted power is no different in conumption to the single phase.
Is air conditioner works on 1 phase and how it works on 3 phase also?
If an air condition is single phase, then it can only be connected to a single phase source. Since any two legs of a three phase source are considered single phase, there is no conflict, except to note that the individual phases of the three phase source match the voltage requirement of the air conditioner.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
Can 3 phase be changed to single phase on the Hobart mixers?
You will need a phase converter. Avaliable at an industrial supply company like granger supply
How do you connect single phase supply to a two capacitor motor?
See Discuss Question below.
Is it safe to connect 380 volts 3 phase supply to 220 volts 3 phase supply?
No.
When would a three phase supply be preferred over a single phase supply?
Bcoz in single phase if supply is interrupt or any trouble there is no power .but in 3 phase if 1phase supply gone we can manage it by other 2 phases
How do you you connect a 4-prong appliance to a 3-prong outlet?
Sounds like you want to connect a three-phase machine to a single-phase supply. Very inefficiently, a three-phase motor can be ran on single phase by electrically displacing the windings with a capacitor. Other than that, you will need to either look at getting yourself a phase change converter, or having a three-phase outlet installed.
Can you give single phase supply to three phase device?
No.

What is typical single phase voltage in Canada?
The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.

Does single phase power damage air conditioners?
If the air conditioner is designed for three phase, then it will not run, and could be damaged, by single phase power. Otherwise, no.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
How do you start a three phase motor to a single phase power supply?
You don't. A three phase motor will not start unless it is connected to a three phase supply.
