I would say it sounds like the compressor shorted or one of the three wires is/are grounding out. This should trip the breaker not melt/burn it. The other option is that the condenser fan is not coming on thus causing the compressor to overload and toasting the breaker. I am assuming that you have a 30/40 amp breaker. Once you install a new breaker the turn the unit on and see if the outside fan is working and is the compressor is running. Hope this helps tim

My brother gave me a air compressor 220 from Home Depot I got new capasotor and I gotten the unit running but stops after 5 seconds the unit pumps up air but did not trip the breaker.

Look on the end of the motor to see if the centrifugal switch is operating. Thats the switch the motor uses to connect the start capacitor you just installed at motor startup. After it runs up to speed the capacitor is switched out . I'll bet it is not working, since you needed to replace that capacitor.

Perfectly working unit, now completely dead...power supply 220 v to circut pane is good

Is there an external outdoor isolator?
Make sure power going through switch as required( put volt meter on neutral and power cable to test not the earth and power) this can also be checked at terminals at outdoor unit, a missing neutral will cause power failure but will not trip the breaker,

Answer not provided. Please read my question.

is it 110 or 220? if it is a 110 first check your breaker/ fuse panel for tripped breaker or blown fuse if 220 it would be a double breaker. if you find tripped breaker remember some panels require you to turn the breaker fully off then back on to reset. if 110 and no blown breakers, check your laundry room for a GFI (ground fault interrupt) outlet. make sure that it is not tripped either. to reset that just push the reset button on the outlet. best of luck to you

I believe I might need to change my (20 amp) breaker switch that is running on 10-2 wire which supplies power to my Rheem Classic 10 Seer. I'm not sure if I need to have 220V of power on a 30amp...

Hello, the unit runs on 220 volts that's why # 10 wire must be used. The best bet is to use a 40amp breaker for 220 volts, gives the circuit more protection.

If its a resistance heater (electric heat) chances are you have a shorted out heater element. This is the most common problem with these units. You can disconnect the 220 going to the elements and turn the unit on and see if it still pops a breaker. If it don't then you know its the heater elements their selfs. If it still pops a breaker then look for a wire that go hot and shorted to either the case or another wire.
Take caution when working on 220 volt equipment as you will get shocked. You should never touch anything inside the unit unless you have pulled the power to it (Turned it off via breaker or plug or what ever means it has to connect the unit to the household electric.).
Hope that helps you.

My pump (pentair whisper flow 1 hp) has been making noise for about a year. Then it started making a clicking noise on top of that, and I knew it wouldnt last but a week. A day later it never came back...

Based on your description of the breakers you should have 230VAC to the pump motor. Even if it is only 115VAC you should still get a response from the unit when powered on. A 230-connected motor will run on 115 for some time but will overheat and eventually fail. If you are getting nothing you have issues with the power as well as the pump. Get the $40-$50 multimeter and check your line voltages to ground and line-to-line. You will find a problem somewhere.

And to answer your other question...yes, connecting 230VAC to a motor setup for 115 will burn up the winding.

The electric power to my house was temporarily interrupted, and since it was restored my Modern Maid wall oven has not worked. The timer and griller work, but the wall oven does not. Does the oven need to...

The timer is 110 volt, and the grill may also be . The oven, however, is 220 volt. Suggest you check your main circuit breaker box and reset the breaker set marked "oven" or something similar. This would be the exterior breaker box where power comes into the home.

I would like to know if I can power my hottub right to an existing 220 line the tub runs 220 volts 36 amps and I have a 40 amp fuse already installed in the house plug

Check your local codes, you probably will need a ground fault current interrupting breaker(GFCI). Do not skip the codes, if anything goes wrong, your insurance company will not cover. Putting a special box GFCI protected will give you extra protected outlets for outside use.
