If you have 4 wires coming from your AC unit put the two colors (usually black and red) on your breaker, white wire on your neutral strip and the green on the ground strip. If I were you, I think I would turn all of the power off before wiring anything..Your Question seems to tell me that you know very little about electricity, so I think I would get an electrician to do this wiring, boy you could save a lot of money in the long run, besides its not safe. I will be glad to help you on this. I am a license electrician.

I have a 1979 Southwind Fleetwood RV I need to replace the circuit breakers and or fuses located in the rear circuit breaker box unit.is there a difference between RV and home circuit breakers?


It could be if your breakerwhen you remove it says 120 volt or 240 volt than no same but if it is saying DC volts than yes different should say what it is on side of breaker or on in side of breaker box door I would think age of rv mostly 120volts

Wiring diagram RUUD UAPA-036JAZ


the condensor gets 240 volts a-c and 24 volts a-c to control contactor. pretty straight forward on this 3 ton unit. the 240 volts comes off breaker box and the 24 volts comes off thermostat and common of transformer.

I need to know fuses box


Copy following link to see basic circuit breaker box.
http://waterheatertimer.org/See-inside-main-breaker-box.html

It appears you are connecting home automation to to breaker box.
Remove one wire from each circuit breaker. Connect this wire to relay. Then run new wire from relay to circuit breaker.
When the relay turns ON, then that will complete circuit to each circuit.
This will work for 240 volt or 120 volt or 277 volt single-phase split phase..

Match wire size and circuit breaker

Heil central a/c will not turn on, model is max performance 14 model # HAC442ACK4. checked circuit breakers


Hello, if the outside unit is not running start at the outside disconnect box and verify if you are getting 240 volts, if you are continue to the contactor coil, check for 24 volts at the contactor coil if there is 24 volts and the contactor does not energize then it must be replaced. If you do not have 24 volts then the low voltage ( thermostat) wiring must be checked out for a short circuit, loose wiring, or the thermostat might be bad. Also, you can check for 24 volts at tjebcontrol board between the r and c terminal if no 24 volts then you have a bad transformer.

I'm replacing my gas furnace with a ac/heater unit that uses 240 voltage and want to know how many volts my furnace uses


If it's a 240 volt system, the maximum voltage required is 240 volts. Which would be what the furnace needs/uses to operate properly. But, I suspect what you really wanted to know is what is the amperage that's used/required. In most installations, it requires to 60 amp circuit breakers. However, yours may require less or more. Check the installation manual for more specific requirements.

The panel turns on but the motor does not turn on. The electronic panel is on but the ac has a humming sound without the motor or the compressor turning on.


Hi, This being 18,000 BTU is a 240 volt unit. The electronic in it work at 120 volts. I believe you have only 1/2 the electrical current going to it. Thus the Hum. CHECK YOUR FUSES OR CIRCUIT BREAKER!
A 240 volt circuit breaker has two sides or switches with a bridge between them. One of them may be tripped. Shut off the breaker wait a few seconds then turn it on so that the it engages all the way. It if clicks or pushes your fingers back and prevents you from engaging it, there is a problem likely with the compressor/fan or it's wiring, and it is drawing too much current and requires repair or replacement.

Hope this helps,
Best, Mark

yes your ok if they say the unit doesn't need to be changed in the incomimg power from 208 up to 230 volts or vice-versa,normally they classify motors as120/208/ 230 /460 volts, instead of 120/240/480 volts,but all line voltage varies in this voltage range between 230 to 255 volts a.c. with a +10/-10 percent tolerance either way,and as long as the instructions dont say anything about changing motor connections your good to go, just look on the motor body if possible and make sure theres no wiring diagrams to change voltage,but i would say no in a package A/C like that, and as far as the current goes your good with the 20 amp tandem pole breaker,let me know if i can further assist you. thanks

How do you tell with a voltmeter if the contactor coil is bad?


Check for 24 volts AC at the coil. If you do not have 24 volts at the coil (with AC turned on at your thermostat), then your problem is not with your contactor, but rather a control problem. If you have 24 volts at the coil, check for 240 volts on the LINE side (commonly marked L1 & L2) of your contactor. If you do not have 240 volts, check for open fuse or tripped or bad circuit breaker. If you have 240 volts, check for 240 volts at the LOAD side of your contactor (Commonly marked T1 & T2). With 24 volts on your coil and 240 volts on the LINE side, you should have 240 volts on the LOAD side. If not, the contactor is not making contact.

You can also perform a continuity test as shown in this video:
