The two wires coming from the breaker box go to the terminals marked "LINE". The two wires going to your AC unit go to the terminals marked "LOAD".

Hope you find this to be very helpful. :-)

SOURCE: outside unit keeps shutting off after 15 to 20 mins.

When compressors are on their way out, this is a symptom that is common.

What size fuse should my split air conditioner have it a teco Lt2421ye8


Each unit comes with a specification label with the information of the minimum and maximum fuse or breaker to be used, Try to locate it at the outside unit. If it not readable use this guide. As a friend for a clamp electrical meter and use the amp to read the current the unit uses in only ones of the live wires that enter the outside unit. then if the current is less than 13 amps and the wire is AWG 14 use a 15 amps fuse or breaker, if is more than 13 but less than 16 and the wires are AWG 12 use a 20 amps fuse or breaker, if is more than 16 but less than 24 amps with wire AWG 10 use a 30 amps fuse or breaker.

Hope this can help.

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.

My amana ac unit over heats the circuit breaker and trips it off after running for about 15 minutes. It will not blow the fuses on the outside disconnect next to the unit outside.


What you described 'shouldn't' be happening - "if" the outside fuses and the inside breaker are sized correctly for your air conditioner.

I would make sure that the fuses in your outside disconnect were the proper size (for your AC), and that the inside breaker was of suffienct size to handle the air conditioner, and whatever else might be on the circuit.

Note: You would never want the 'outside fuse size' to be bigger than the inside breaker.

For example: 50 amp fuses in the outside disconnect and a 40 amp inside breaker is a no-no.

Often, for whatever reasons - someone will put larger fuses in the outside disconnect than what is called for.

When this happens the inside breaker is the only safety on the AC.

The problem is - for whatever reason - your inside breaker should not be tripping off.

It's likely that the AC may be on a inside breaker "that also has other things i.e. dryer, electric range or Refrigerator," and therefore any of these components 'including' the air conditioner could be causing the inside breaker to 'trip.'

One way to check this would be to 'un-plug' whatever else you had on the inside breaker - and then run your air conditioner and see if the breaker trips. Let's say you have the refrigerator and the air conditioner on the same inside breaker. You suspect the refrigerator is causing the inside breaker to trip - so you unplug it - and then turn on the air conditioner. "Now" it does not trip the inside breaker and assuming you have the proper fuses in the outside disconnect - you could safely say the air conditioner is ok - but - the refrigerator might be on the blink.

It's also possible that you just have too much on the inside breaker and you need to plug the refrigerator in to another outlet.

Still, if it was me - I think I would really think 'hard' about calling a Service Tech out - and let him/her diagnose the problem.

Hope this helps.

I have a rheem criterion ii a/c and furnace. The power source from the a/c outside unit is not hooked up inside. Where on the unit indoors does the wire attach.


two wires go from the inside unit to the outside unit. Y terminal and C terminal (both low voltage). Power should come from circuit breaker panel (20 or 30 amp double breaker).

For an 3 Tn unit- single phase- 220 V a.c and gfor


There should be a full load amps or rated load amps on each of these units on the rating or nameplate. The ampacity or fuse size and wire size, which I think that's what you are wanting to know . The fuse size would be full or rated load amps times 125% and the wire size depending on the length of the run, 50 feet or less, (15 amps 14 gauge wire), (20 amps 12 gauge), (30 amps 10 gauge), and (40 amps 8 gauge).

Window A/C Air Filter is Soaked


There is a drain tube that usually runs to the outside that is suposed to carry the water away from the unit. It may be plugged. You could use a shop-vac from the outside to pull it through. If you have compressed air you can blow the obstruction out to the inside. Be aware this could make a mess on the inside! After clearing the drain line I would leave the unit off for an hour or so just in case there was any frost building. Then turn the unit back on. If it continues to get wet then the unit may not be leveled correct, or maybe it is low on refrigerant causing the frost on the inside.
