The three phase supply first has to be connected through a three phase safety disconnect switch. From the safety switch the three phase supply then connects to the terminal strip that is supplied in the air conditioner's control panel. The air conditioner unit is factory wired so that all that is needed in external connections if the power and thermostat control.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 12y agoIf you have a 4-wire receptacle it is likely 240 Volts and one would hope that you are connecting a 240 V AC unit. A typical 4-wire receptacle will have two hot terminals (Usually red and black), a Common terminal (White) and a Ground Wire (Bare or green).
If you have a 220 V AC then you need to connect to the two Hots to get 220 and connect ground to ground. If your AC was 120 V you just need one leg of 240 V so you would connect to Black, White and Ground.

∙ 12y agoA 30 HP 200 three phase motor draws 92 amps. This supply is going to need a feeder right back to the three phase electrical distribution panel. The first question can this much load be added to the distribution. This is a complicated job in as much as you have to know wire sizes, ampacity of wires and proper electrical workmanship. Such a project should be left to a licensed electrical contractor to take out the proper permits and call for proper inspections. By taking this route it will leave you confident that if any mishaps happen to the installation down the road your insurance company will be behind you 100%.

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.
Can you tap off a 3 phase 277volt ac light fixture to power a single phase 120 volt ac recptacle?
NO! The voltages available in the 3-phase system are 480 (if you wire phase to phase) and 277 (if you wire phase to neutral) Don't try it!
What are the procedures for the connection of single and 3 phase circuits?
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt

Explain the comparison between dc 2 wire system and ac single phase 2 wire system and ac 3 phase 3 wire system and ac 3 phase 4 wire system?
of all of dem 3 phase 3 wire is most economical as it uses less conductor dan in 4 wire system, 3 phase 3 wire is used in transmission and 4 wire in distribution as it has 3 live and one neutral wire. 3 phase needs lesser conductor size than 2 phase 4 wire for the same power. 3 wire dc feeder is more economical than 2 wire dc feeder for the same power. that was all i cud get..... hope u find it a lil helpful.
How may wire on a 3 phase motor?
3
How many wires come in from the weather head?
If single phase - 2 wire service > two wires If single phase - 3 wire service > three wires If three phase - 3 wire service > three wires If three phase - 4 wire service > four wires US residential service is usually single phase 3 wire service: Two hots and neutral.
Which connection is best suit for 3 phase 4 wire service and why?
STAR connection is best suit for 3 phase 4 wire seviceas there is a neautral wire is there in this connection

What size circuit breaker for a 208 volt 3 -phase 8 ton air conditioner?
Look for directions on the air-conditioning device and you will see how many amperes it spends. I believe that is 10 A on average.

How do you wire a 1 to 3 phase roto verter?
How do u wire a 1 to 3phase rotoverter
Why does my air conditioner in my truck only blow air?
Check the following............... 1. Freon system level. 2. Pressure switch. 3. Clutch wire harness. 4. If above are okay then scan the vehicles computer.
