A volt transformer is typically used as a control device to turn a higher voltage, generally VAC, into a lower working voltage for switches or relays, such as in a furnace thermostat transformer. If you are noticing bad furnace transformer symptoms, such as regular blowouts, run through a basic testing procedure to ensure your volt transformer is operating correctly.
Before you do any testing, remove all electrical power from the electrical appliance or device. Never carry out testing with an outside source of electrical power going to the device. Always test in a safe, dry place that is away from children and animals. You should only test a transformer if you are comfortable working with electrical equipment and are familiar with a multimeter, which is a device that measures electric current, voltage and resistance over several ranges of value.
There are two sides to the volt transformer: A high side and a secondary — or low-voltage — side. The high side is the line-voltage of the transformer and the electrical connection to the feeding voltage, generally a VAC power. The secondary or low-voltage side is the power that is transformed into 24 volts. There is no direct electrical connection between the high side and the low side areas of a transformer used for a volt application.
Use a screwdriver to remove any electrical covers that may conceal the transformer. If necessary, check your manufacturer's instructions to ensure you access the transformer correctly. Use a multimeter to test your transformer.
Switch the multimeter to "ohms" and insert the red and black test leads into the meter. The red lead goes into the slot that reads "ohms" and the black lead goes into the common opening. Touch the two leads together. The ohmmeter should read zero ohms or a closed circuit. Place the leads of the ohmmeter to the leads on the high side of the transformer. The meter should be identifying a resistance reading.
This reading will vary by the type of transformer used in the circuit. If the meter indicates an open circuit or infinite resistance, the transformer is bad on the high side and must be replaced.
Follow the same procedure on the low side connections.Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community.

Lighting ballasts generate an initial high voltage to start the arc that excites the gases in fluorescent and HID lamps and makes them shine. They're usually rectangular black boxes with wires coming out of one or both ends.
Lighting ballasts for fluorescent light bulbs and HID lamps made before may contain polychlorinated biphenyls PCBs. Because ballasts can last for 30 years or more, there are still some PCB-containing ballasts in older buildings. Fortunately, you can easily tell whether a ballast contains PCBs.
How to Test a 24 Volt Transformer
Ballasts that have PCBs are regulated by the U. They aren't hazardous when used as intended, as long as they don't leak. You may be able to dispose of a few intact ballasts containing PCBs the same as ordinary trash or at a household hazardous waste collection event or drop-off location sponsored by your county, city, or waste disposal district or company.
Many states have developed regulations governing the disposal of intact ballasts containing PCBs that are more stringent than Federal regulations.
If you have a lot of ballasts the number varies by State or if you have leaking ballasts, special disposal is required through EPA-approved disposal methods. Because requirements vary by State, check with your regional environmental engineer Web site available only to FS and BLM employees before making disposal decisions. Health Issues : PCBs can enter the environment through both use and disposal. Severe concentrated exposure to PCBs can result in skin lesions, liver damage, or other problems.
Lower level exposures are more common, and typically occur through eating contaminated fish, milk, or other foods. Over time, lower exposures may result in thyroid, immune system, and reproductive system problems and cancer. Infants born to mothers that have consumed PCBs may have problems with motor skills, hearing, and brain function.
Engineering Home Toolbox Home. Is there a problem with dumping old lighting ballasts in the trash?So I am getting a Ring Pro doorbell for Christmas to integrate into my Smart Home… I am starting to think about installation I have been reading online…seems like of folks say just upgrade to a 24 volt transformer and save your self a headache.
So I took down my doorbell just now, and while my transformer is actually setup to handle either 8 or 16 or 24 volts, my doorbell chime says on it for 16 volts.
Looked on Home Depot, Lowes, and Amazon. Your thoughts? My doorbell transformer was measuring at All is good since then. My old lighted doorbell in my garage is now much brighter with more voltage but all is good.
Lowes carries the transformers and you choose which voltage to use so try that first before replacing the chime. Yeah just give it a go, if you get issues that could be down to power, replace it otherwise you may well be fine. I installed a Ring Pro four days ago… My chime is a 16v system.

Testing the leads at the bell I got readings from Setup was pretty straightforward following the Ring Pro instructions although I HATE the snap connectors in the kit for the pro power unit. I replaced them with my own small gray wire nuts. I had everything connected according to instructions and was reading through correct voltage at the leads and installed the doorbell and got… Nothing.
Zip zilch, nada. I figured I had to have borked something in the pro power kit install so I pulled everything out and reinstalled everything. Tested voltage and tried again. I called Ring support. They walked me through everything I just did and added one step. Short across the bell wires where the doorbell connects to test if I get a bell yes, I did.
Yes, let it sit. Lesson: check all of your connections and be patient when you turn on the breaker the first time. Same hete. I tried everything including new doorbell chime same as in install video. Had to wait an hour then started working. Working good.
I have the same kind of transformer and my Ring Pro works just fine on 16V.Installing low voltage lighting is easy for any homeowner. This project can be tackled in a single afternoon, and is even easier if you are already working in your flower beds.
The lighting highlights features of your yard as well as provides safety and security around your home. When our giant pecan tree dropped HUGE limbs and missed our house twice, we had to remove it. I can take a hint! After it was removed we were left with a messy flower bed, and the front of our house was wide open; we needed some curb appeal!
After planting all new flowers and shrubs, the finishing touch we needed was outdoor lighting. We wanted a landscape lighting project we could do ourselves, so we opted for low voltage lighting we could put in without calling an electrician. The lights will come disassembled, so your first step is to put them together. Decide where you want the transformer. It needs to be mounted off the ground near an electrical outlet. We put ours on the wall on the corner of the front porch, close to the wall outlet.
It could easily be hidden by a potted plant. Layout your fixtures and decide where you want them placed. Make sure the first light is at least 10 feet from the transformer. We had one section we had to run under the grass so we used the shovel to cut a trench, bury the cable, and then lay the grass back over it. The far end of the cable the one not attached to the transformer can simply be cut and buried.
Leave about 12 in. Refer to the strip length guide that came with the transformer. Note: if you use a different kit or add lights, consult the package to ensure you are using the correct transformer and cabling. To connect the cable to the transformer, lay the transformer on a flat surface. Gently pull on the cable to ensure the connection. Also, make sure there is no insulation under the clamping plate! Let there be light!
