It's possible the transformer is bad, but maybe a primary fuse or switch is out on the 13kV side. Check the secondary connections into the delta at the transformer. Good luck!

You can safely use any ul approved device using 120v 50 ~ 60 hz if you stay within the limits of it's potential (in your case 2000 watt). You will probably have a loss of efficiency using a step up transformer and will be very limited on the wattage available at the 220v. Most converters are not designed for continuous use and recommend that you buy a converter with at least 25 % more capacity than you will use. Also to get longer life out of your generator, you should use only 75 percent of its capacity for continuous use. A 2000 watt converter will work fine for loads of about 1500 watts or less.

If no one has the specs on this transformer but you know the power rating, apply this formula: Power/Voltage= Amperage. It might not be a big help but it sure will put you in the right range. The other solution would be to obtain a schematic or parts list for the unit. Hope this helps!

What do i have to do to plug my 110 air conditioner into where my 220 window unit


You need a step down transformer, to convert 220V to 110V. You can't just plug the 110V A/C unit in directly unless it is clearly marked as being suitable for multi-voltage supply (110V - 220V input).

Such a transformer has to be of sufficient capacity to handle the current, or wattage, that will be required. The Frigidaire unit in your question is a 3.5 kW cooling capacity, so the transformer would need to be about the same, ie for a 10A supply at least. They are quite big boxes, about $120.

You would put this in the roof or in a cupboard.

AC Power Failure


Providing that you the outlet is putting out proper voltage, check the voltage output of the plug in transformer. Used a voltmeter set to AC and attach the leads under the plug in transformer (where the wire normally go) and plug back into the outlet. The voltmeter should be reading around 9 volts AC. If there is no a low or no reading, you have a bad plug in transformer. It can be replaced with a 9 volt AC 25 volt amp transformer. Battery may also have to be replaced, if it is depleted. If this does not fix the problem, you have a bad panel and it will need to be replaced.

It does not appear that my Carrier Infinity 96 is supplying the 24Vs required to my humidifier. Is there a swich on the control board that needs to be on or off to enable the humidifier power?


Hello, the control board supplies 120 volts to a transformer and then the transformer steps it down to 24 volts. check to see if you are getting 24 volts at the transformer if not then turn off the furnace and check the Resistance of the transformer, you should read resistance if not the transformer is bad and must be replaced. If you are not getting 24 volts and the transformer checks out good then a problem could be the wires going from the board to the transformer or portion of the control board is bad.

How do I wire a double pole double throw 240 volt ge intermatic timer to 4 240 volt plugs?


You posted under GE timer, but added the brand name Intermatic.
GE and Intermatic timers are totally different.
Wiring below is for GE and will not apply to Intermatic.

Step 1) lets cover basic GE timer wiring for 240Volt load.
Be sure to set dip switches BEFORE applying power.
Step by step illustrations show on following link.
http://waterheatertimer.org/How-to-wire-GE-15207-timer.html

Step 2) Load wires exit GE timer.
There are two Hot wires and 1 bare ground wire.

Step 3) Wire the outlets: You have 4 240Volt plugs.
This could mean a receptacle-type outlet like a clothes dryer outlet or air conditioner outlet.
Or it could be a twist-lock receptacle or extension-cord-type stage plug.
In all cases, look at screw color on device.
Connect Hot wires to brass colored screws.
Connect ground wire to green screw.

Step 4) Calculate total Load
Manual appears below: Look at Normally Open contacts. These contacts turn ON when timer turns ON.
http://waterheatertimer.org/15087-15207-56922-Manual-eng.pdf
Total load on all 4 plugs cannot exceed 2 HP
Generally, a 30 amp timer is rated for max 24 Amps or 6 amps per each of the 4 plugs.
Volts x amps = watts.
Take total watts and divide by 240Volts to get amps.

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

I am looking at a 480v fed chiller. It seems to be wired so they can also drive a 120v pump from the same 480v feed. Is this possible?


From what I found, 480 volt, 3-phase is 480 volts from leg to leg.
It is also 277 volts from each leg to neutral.
One can use a step down transformer to reduce the 480, 3-phase to 208 v, 3-phase and then each leg of the transformed voltage would be 120 volts to neutral. Try to locate the transformer in or near the chiller control cabinet.

I have a GE Simon Security System with a GE Simon 3- X10 Line Carrier Transformer that powers a siren. Since the X10 transformer was installed, I constantly get sensor 'failures.' Although the panel...


X10 is a signal format transmitted over the power lines, there is no special X10 wiring in the house as such. The siren and your outside lights are X10 receivers which are sent a signal from the X10 transformer connected to the alarm panel. The alarm panel sends the codes which are transmitted as X10 to the X10 external devices. Most houses now days have at least two 120 volt feeds coming into the main power panel, this provides the 240 volt required for electric stoves and dryers. Because of the two separate feeds split at the panel, the 60 cycles is usually out of phase with each other. To get X10 to work and stay in phase on each side of the panel you need to have wired a passive coupler across both 120 volt inputs. This coupler keeps both 120 inputs in phase with each other and provides a clear X10 transmit across the house wiring.

How can i convert our 220 volts wall outlet to 110 volts for a microwave oven.


Find the breaker for it (a double for 220) and substitue a single breaker (for 110). This will leave one wire unused from the breaker box to the outlet. You'll have to change the outlet of course to accommodate a normal 110 plug. You can also skip the breaker part and just change the outlet and cap off 1 of the hot wires. Just make sure to kill the power and be safe!
