What is this?

A few years ago we converted to central air from a gas fired boiler. The company removed the boiler but left some of the wiring that I am trying to clean up. I am curious to what this item is. It has 120 to it as well as what looks like the old thermostat wires. Is it a co monitor?

That is a doorbell chime transformer. There is a possibility they used it for the thermostat controls for the old boiler system.

Disconnect the exposed low voltage wires and see if your door bell still works.

If it's connected to the thermostat wires, then its not the doorbell transformer.

The only definite thing is that it is a low voltage transformer. You need to figure out if it's still being used and for what if it is.

It was abandoned as a result of the new boiler project, yes? It wasn't already abandoned in place prior to the upgrade?

Either way, it's a small transformer.

Carbon monoxide monitor? What on earth led you down the path to wonder about that? (No insult intended there -- just kind of a big leap!)

It was hooked up to the same conduit feeding an boiler in an enclosed space. I didn't think it was that was that far of a leap.

Do you have a doorbell/chime? What is the secondary voltage?

Does it only have two wires connected to it? Has any wires been cut off of it?
If it only has two possible wire connections, then it is not a transformer. A transformer has a primary and one or more secondary, to either step down, step up, or isolate 1:1.

Looks like it is adding inductance to a circuit for a reason, if those are low voltage cloth covered wires that is. Or to keep a load on a circuit if those are 120v wires.

The primary connections are likely inside the box it was mounted to. I've not seen one of those low voltage transformers with exposed primary terminals. That would be a bad shock hazard.

It has upstream wire that is definately 120v the down stream is cloth covered wire that is breaking down. The new thermostat is fed from the new furnace and the doorbell doesn't work, so I guess it can go away. Thank yall for all the great responses. I really appreciate it.

The other 2 wires go in thru the cover plate it is mounted on.

To the OP: Tell us about the band aids. :willy_nil

The bandaids are from splitting kindling. My boy scout hatchet has been dull for over 20 years, so I finally decided to sharpen it. I got it shaving sharp like it should be, and then promptly forgot I sharpened it. Enter the bandaids.

Man, the guys in here don't miss anything do they? I never noticed the BandAids....

Thanks for the explanation. That kind of thing happens to all of us. :thumbup:

Most likely the old xformer for the heat. Seen probably one hundred exactly like it over the years...
