    Can't figure it out. In the basement, there's this thing plugged into the wall. It has a slight hum. The wire leads up into the ceiling and disappears. Any idea what it could go to? Not sure why its zip-tied. Can't get a clear shot of the labeling on the wire to see the gauge. It's not a...

    Hello, Ya'll! I hope you are all well and safe in this crazy world! Is it possible to use a 220V dryer with a step-up transformer of ample amperage on a 110V circuit? The dryer has a 4-prong plug. I have not seen any adapters, which let you plug in a 4-prong dryer plug into a universal 220V...

    Hey everyone, I was exploring our house and I think I found our low voltage transformer, it looks as though the previous owner decided to camouflage it! This house does not have a doorbell, BUT when I crawl into the attic space I see bell wire which might lead to this sucker. Any opinions or...

    I have recently begun investigating our home and noticed that the electrical panel is located outside our home. It appears that wire is run under our home through the crawl space. I had plans to install a doorbell to the panel as there is no existing doorbell for our home. However, I have no...

    Hi: I have an older desk lamp that has a cord with a transformer, stepping it down to 12volts. I want to swap out the tiny bi-pin bulb that getS SUPER hot with an LED version. All I can find are 120v versions that fit this particular style. Can I simply cut off the transformer and rewire the...

    I purchased an air purifier printed 110V. It comes with a power adapter of 100-240V. Can I use the air purifier with a power supply of 220-240V? Is the adapter also a converter or transformer? I’m really confused.

    Hello, I need to mount a doorbell transformer (24V) to a junction box in the attic. The transformer has a mounting screw and I know that the high voltage input (120V) is obviously enclosed inside the box and the low voltage is outside. My question is, does it matter whether I mount the...

    Hi, I am replacing my old thermostat with a Nest smart thermostat. The Nest requires a 24V input. I removed the old thermostat and luckily there are two unused wires that are taped up in the junction box, which trace back to a 24VAC transformer in the attic. So it appears I have the wiring...

I just had a tech come in and did the yearly cleaning and maintenance, then this started happening.The tech...

    I have a 24-volt lamp on my front lawn that receives power from a 24 volt AC, 50 volt-amp transformer that is plugged in in the basement. The transformer that came with the house when I bought it stopped working, so I bought a replacement Class 2 24VAC, 50VA transformer to replace it. The new...

    Hi all, I just discovered this forum, and thrilled to dig into all the great content! I run a small letterpress printshop in New Hampshire, and just acquired a small piece of bindery equipment that I'm trying to get running in the studio. I'm generally mechanically inclined, but less so with...

    Hi all, In relation to this post: https://www.diychatroom.com/f17/erie-sr-601-goes-sleep-647863/#post5703197 My Erie SR-601 zone relay is now overloading more than ever. It definitely needs more juice to power all the nests. How do I go about adding/replacing the transformer in the relay? Any...

    I have a need to distribute 120v lighting and receptacle circuits as far as 500' from the nearest structure. I started a thread that has expanded in scope and I wanted to start a separate one only for the idea of using an external transformer. I like the idea of running 240v out 300' or so...

    I live in a house that seems to have been built out of spare parts by the previous owner. I recently had a lot of work done after Harvey flooded it, and the workers took my doorbell assembly apart and left it half there on the wall. I bought a new wireless system and installed it, but I want...
