Most typical local practices are; (Brown-Orange-Yellow) for 480VAC 3Phase

The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors

I have old carrier 50zp060511s Air Conditioners that having voltage details like 3ph 220V 60hz UL Standard But now i have voltage of 400V 3ph & 230V 1ph.. is there any solution for this issue..


If you are reading 400 volts coming into the unit, call electric company. You should only have 220-240 from your power lines. Anything over that will burn out unit. P.S. In my opinion Carrier Units are the best and longest lasting when properly maintained.

Mars blower motor diagram?4 wires


Gentlemen,
I have a GE P547BS fan motor. I find replace it with a Mars 10584 fan motor. GE has five wires, BRN, YEL,PUR,BLK,RED. Goes through the capacitor with the yellow going on to 200 V the purple and black go to 220 V. Mars motor as a six wire connection two Brown's go to the capacitor. yellow I'm assuming goes to the hot/neutral and a black I would say would be high-speed blue is medium and red is low. Now when I connect with this way it blows the fuse. Anybody run into this problem before? Any help? By the way, it's a 240 V single phase system.

I have a Rudd 240V air cond and changed out the condensor fan motor that had 3 wires brn, blk and org. the new one has 5 wires,brn,blk,org,blu,yel. which wires do I connect to relay and single capacitor.


If you will look on the side of the new motor is should show you. But the black and brown will go in the same place as your old one. Generally, the yellow will replace the orange.
Black is hi speed and will be connected to one side of the "relay"
Brown is capacitor by itself
Yellow is common on the other side of the capacitor and will link back to the "relay"

Again, be sure to check on the side of the motor. Yellow should be noted as "common"
Be sure to tape the ends of the wires not being used before you power it up.

Industrial building built in '93. They used 277v (coming off one leg of 480v 3PH) for lighting high bay lights. The number on the line taps for pugging in the lights is: LDM2. This plugs into a G1...


Any electrical supply house should have the wire tap connectors. Your new load depends also on the current draw of the existing load, the wire size, and the circuit breaker or overload heaters on the circuit. If the total load is less than the rating of the wire and protection, then yes you can tap in without causing an overload condition.

Unsure of capacitor terminations for ao smith condensing fan moto


Does the motor data plate say anything about the motor. You can hook up a motor like yours with 3 wires. First use an ohmmeter and check the resistance between the brown/white wire to the black then the yellow wire. The resistance between brown/white and one of the others should be pretty much 0 ohms. If not check between the brown wire and the black and the yellow. Which ever wire has 0 ohms with the brown/white wire is the common leg. You can put a wire nut on the brown/white, it will not be used. Next the brown should be for the start winding and the other wire left over will be the run winding. Then connect the common to L2. L1 will go to the run winding and one side of the capacitor and brown will go to the other side of the capacitor. I hope this isn't too confusing. Let me know if I need to explain it better.

Bought A new daton fan motor to replace the old one and it spins backwards now


You didn't give any model numbers so there is little to go on, but typically a motor spinning backwards has been wired incorrectly, particularly if it is a 3ph motor. There could be other causes but in 3ph motors this is the most common.
Good luck!

We have an Singer electric heater. It is 480v 3 phase Commercial forced air. I need to know what size breaker need to pull this much power and also I have no instructions for hot ground and nuetral...


You cannot hook this thing up unless you have 480v 3 phase service from the power company which you will not have unless you are some kind of industrial operation. There is no neutral involved in 480 3~ only three hots on different phases and a ground for safety. If you do happen to have this kind of power available you should call a professional to do the work for you. Judging by your understanding of electricity based on the question you asked, you will most assuredly kill yourself in the process of trying to hook this thing up.
