What popped? the new fuse or something else? The pc board will have a transformer built on it. It looks like a little coil.The fuse is supposed to protect that, but if you replaced it with a larger amp that the original, then , it may have burnt the coil out. The plug is supposed to be a different design to prevent the wrong voltage from being applied like your case. Why was this able to happen? For example 208 looks like I- and 120 is like II

I have Mitsubishi Mr. Slim Model R410A and the outdoor unit is not working the fuse was burnt I changed the fusebit is still not working


Could be several things causing the problem. You didn't say what size fuse you replaced. If you replaced the small fuse on the control board then you probably have a bad board.

If you replaced the fuse that provides 120/208 volts to the unit then either the compressor is bad, you may have a short in the power wiring or the fan motor is bad.

All three things can cause the fuse to blow.

I purchased a generac 22 kw 3 phase 120/240 volt generator. I was surprised to find that it had a wild leg. Can i change the leads on the stator output to eliminate the high leg and get straight 120/208...


This unit is wired 120-240V 3 phase Delta. if you are using on it 120/208V 3 phase application it will need to be re-tapped. If you are using it in a home 120-240V single phase it will need re-tapping, Do NOT just use 2 legs, as this will cause rotor imbalance and wear out the rotor bearings, and odd ball currents to flow. If there are 12 leads coming off the stator it can be reconnected. If not you are stuck with it, except by using a transformer

Wiring a dimmer switch with 208vac, single pole


208 Volt 2-wire is generally achieved by pulling two hot wires off 3-phase 120/208 Wye or 208 Delta, or Highleg to center tap off high leg delta.

http://waterheatertimer.org/images/3-phase-timer-diagram3-T104-208-240.jpg

Since each of these three phase systems also offers 120volt for lights, and a dimmer can be used for lights, then I wonder what you are using dimmer for?

208 volts.can be controlled by turning off one hot of the two hot wires.
Install dimmer on one of the hot wires, and see what happens.
Is the dimmer rated for 208 volts?

120v on bake element red wire and element wont heat up


the reason its not heating is because you will always have 120 volts on this red wire due to its being connected directly to one side of the in coming power source,its either that you lost the other 120 volts of power coming into the unit,a tripped breaker/fuse/etc. or the control board relay that supplies the other 120 volts to the element for a combined 240 volts needed to heat the element,if you have 240 volts to the connection to the unit then you either a bad control board or the Neutral incoming power wire could be burned off which you need to get 120 volts to operate the control board which operate the relay to supply the element with the required 240 volts to operate

Okcarltons one additional question. how do i identify the 208 volt side of the transformer


Follow the wires the 208 volt will lead you to the fuses or breakers, the 24 side will go to sequencers relays coils, thermostat ect. one side of the 24 volt will usually go to chassie ground.

Installing an 24,000btu air conditioner. The original wiring at that outlet has an double pole 20amp circuit breaker. The old air conditioner that was their was plug into an outlet box that sat on the face...


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

We purchased a Amcor Amcoraire Mini Split Unit ? 12000BTU However the Power Transformer Input: AC115-120v 60hz Output: 10.5v 550mA isn't working as per the installer and we can't seem to find it...


Hi, this is a 1-ton cooling unit per your numbers. If they just installed it and the line side (120 volts) is good but nothing on the secondary low voltage side, they should have replaced the transformer themselves? If it is a split system, it is normally on all splits to be located in the indoor unit control section. I can't tell you exactly, but look where the 120 volts come into the indoor unit and the high voltage wiring should be connected to it then stepped down to lower voltage. It may have a fuse on the circuit board that they blew when installing it. If you are not familar with electrical, I wouldn't attempt to make these repairs. You can look for a small plug in type fuse to see if it blew, it looks like one on your automobile. I would call this installer out and its there job to do this!! These transformers look different, there not all the same, but will have a black and white wire coming in, and several colored wires coming out for low voltage. It will be in the indoor unit. Keep me posted on what you find or if you need more help. How long ago was the unit installed?

Electrical wiring for 120/208 service as opposed to 120/240 service


Your machine requires 208-240 volts to operate with each leg being about 120 volts. Move refrigerators are 120 volts so even though you have 20 amps you probably only have 120 volts.

You can go to the Bunn website (bunnomatic.com) click on Commercial then on Publications then Illustrated Parts and Service manuals and download the manual for your machine that shows how the wiring hooks up in the machine and the type of cord the machine requires to handle the voltage.

The plug you need must match the receptacle in the wall and there are numerous 220volt plugs and receptacles on the market. Don't get a dryer plug instead try for a twist lock as they are more reliable.

Kenmore electric range 7909083461 not reaching temp


The technician is right.  The electrician should know that amperage X voltage = wattage.  So if you lower the voltage then you lower the wattage.  The element is like a light bulb, the higher the wattage the brighter or hotter it will be.  208 volts is at the minimum so the element won't be as hot as it should be.  208 volts is just enough to make it work.  Would appreciate a solved rating for expert advice.
