You need to use a volt meter and test which lead from the 4 wire output of the generator a 220 v is coming out.

the round center prong of the ac is its ground and should not be connected to any live power. it could be left unused.

tnx 4 using fixya,

HELP???


What was the voltage that you measured? Are the units 220 volt or 120 volt. Units that size are usually fed by 220 volts. What is the current rateing of the circuit breakers? Are they a double breaker with a handeling capacity of 20 amps or are they 15 amps.

You didn't mention if they ever worked? Are you feeding 120 volts or 220 volts to the two units?

Good luck,

Marty

HOW TO WIRE E3EB-20 TO PANEL BOX


I'm just assuming that is 220 volt 20 amp The wire that is run is likely a common romex 12-2 NMD-90 Strip the 2 wires put red tape on the white wire as it is no longer a neutral. Hook both wires into a double 20 amp breaker. Put the ground wire onto a ground screw.

Need to how the power source will be hooked up, and how, it will wire into a 13 SEER Goodman Packaged Unit, with HKR-15 strips. wire size?= 15 Ft. run: panel to unit


Minim 20 amp circuit ... is this 110 or 220? You need to know.

20 amp circuit needs to have #12 wire. If 110 Volts, you need a black, white and green #12. If 220 Volts you need a black, a red, and a green. If you have anything IN the unit that needs 110 (probably not), you need black, Red, White and Green (bare) #12 wire. Definitely needs to be on a dedicated circuit. If your unit has a resistance heater (electric) you will need a 30 amp circuit (probably 220) which needs #10 wire minimum. 220 volt breakers are double. You will need two spaces in your panel box. Would not hurt to put in heavier wire (#8) protected by a 30 amp breaker ... $ is the governing factor.

Having said all of that --- you should be reminded that I dont even know what country you are in nor your prevailing voltage nor what your national or local codes require. My comments based on installing several Goodman products over several years on the Eastern Seaboard.

I installed a shur-dri 4"


Hello
If this is a 220 volt pump then it needs to have 2 hot wires,so it would be connected to 2 15 amp breakers.The ground shold run from the pump back to the fuse panel box ground bar.

If this is a 115 volt pump it should be connected to one hot, one nutral, and one ground.

Possible a hot wire is making contact with water and tripping breaker.Or the pump motor is going to ground which means its no good.

Model # ckl49-il serial # 0506126514. This unit stopped working yesterday, noticed the fan on the outside compressor wan't turning, how do i test the capacitor and fan to see which one to replace?


By far the most common problem with air conditions is the relay (known as a "contactor") by the air conditioner industry. This allows a low voltage (24 volts) electromagnet to turn on the 220 volt motor for fan and compressor. A replacement will generally cost about 50 to 75 dollars on Amazon.com.


Look for the wires entering the unit, The pair of wires entering the unit will go into a small (4" x 2" x 2") unit (the contactor). Another pair small diameter wires will go into the contactor (those are from the thermostat (or control panel of your furnace blower) and control the electromagnet switch.

The pair of output wires exit the unit and go to the compressor motor and fan.

You can check the output power by
1) Turning off the circuit breaker to the A/C
2) Unplugging the switch (must be a second switch within 3 feet of the A/C) near the house
3) opening up the outside panel on the A/C
4) Set voltage meter probes on the two output wires on the Contactor (make sure voltage meter is set to 220 volt AC range or higher)
5) turn on the outdoor switch
6) turn on the circuit breaker (if no body is near the unit and you can see the voltage meter without touching it)
7 check voltage meter to see that is says 220 volts AC

If not, then the contactor is bad and needs to be replaced.

A professional can usually do it for $200 including service call. I highly recommend calling a professional if you feel uncomfortable in any way about working with 220 volt systems. This voltage will kill you if you make a mistake!

My AC unit has three wires, green, white red. Coming off the house and off the unit. How do I wire them!!


Hi, if you are talking about the wires,high voltage wires coming from the breaker box, and the same coming from the outdoor unit which are also high voltage wires, you have to set a disconnect box and mount it with in 3 to 5 feet from the outdoor unit. I am assuming you had no prior a/c unit there? If not, the 3 at the house must be ran out of your main breaker box through a breaker, double pole. It needs to match the rating of the voltage on the data plate on your unit, lets say, 30 amps. From your breaker box it needs to be ran through water tight conduit over to the box you will be adding there. Even though you have a green for ground, white and red, the white should be 120 volts and the red the same to have 220 volts. They will wire in this box to the line side. The directions in the new box will tell you line/power in and load/power out to new unit. This box you will need to buy is either a 30 amp or 60 amp disconnect. From the new unit, you will need to buy enough wire of the same size, and a piece of 3/4" seal tight flex conduit and 2- 3/4" connectors. Pull the 3 pieces of new wire through the flex conduit and connect to the 3 wires there. The green is ground so just connect it to a ground or the case. The other end will go through a knock out plug into the box and will connect to the load side. There will be a lug for the green ground. Coming from the house at the breaker box is where these 3 wires should be, and coming out of the breaker, you can use the 3/4" seal-tight to pull enough wire from there to the new box. This is what feeds your outdoor unit. This is just for the outdoor unit. The indoor unit runs on its own power source. There has to be a box mounted there also and wires pulled from the main breaker box to the indoor box. Hopefully who ever installed the unit has done all of this. If you have all of the boxes already there, just hook color to color. If you have never had a split system a/c unit at your home before and you are doing this yourself, there is a lot of high voltage wiring that has to be put in to run both the indoor and outdoor. Get back to me a let me know what you have to work with and if you have ever had a system like this before, and if you set the unit and installed the duct work.
Sincerely,
Shastalaker7
PS If the indoor unit is gas fired, the high voltage will be 120 volts. If its a heat pump, it will be 220 volts.

Goodman PC060-1B Package AC...Need Wiring Help


Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus

Ac wiring problem


as a general rule ,only if your ac was a window unit. aka a 120 volt unit . all other acs use 240 volt. a 120 leg and a 120 2nd leg to equal 240, so there is really no common. what kills acs with a generator is the lack of watts and starting torque. an ac (3 ton) and up needs a generator of 10000 watts minimum to handle starting trque. they also need a hard start kit to boost starting voltage.for god sake someone reply and tell me what a good job i am doing!!!!!!!as in grade the response to your question.
