Here are 2 popular form-factors for 24V transformers: Mounts to a knockout on the side of a metal box. AC mains wiring is inside the box, 24V is outside. Obviously this requires a metal box somewhere whose sides are exposed. Mounts on the face of a 4x4 metal box, replacing the normal lid. Again AC mains is on one side, low voltage on the other. Humidifiers and Dehumidifiers - How to install Aprilaire 24V relay -- no junction box on furnace - I'm installing an Aprilaire 500A and I'm not sure where to put the transformer. My furnace doesn't have a traditional junction box with knockouts. It has a hole in the side where romex enters through a plastic clamp, and It is legal to install a humidifier on the furnace circuit by 422.12, exception 1. However, if no humidifier is present and this is a prewire, an inspector could easily require it removed by stating it is a general purpose receptacle, since there is no appliance that the receptacle is currently powering at the time of inspection.

mounting transformers to junction boxes
Now, you can attach the 24v doorbell transformer to your electrical junction box, as explained by Wayfair. Remove the cover, thread your power supplies' wires into the correct hole and place the transformer in the opening on the side of the box. If there is a bolt, use a screwdriver or wrench to tighten it.If you know where your transformer is (normally placed on side of your electrical panel) you can simply swap it with a more powerful one, "24V 40vA" for example which could power ~4 cameras as each requires 24v exactly at .5 amp each. You would need to kill the power as 120v connects to the transformer.
No, that's no worry. That's a good way to install that, actually. The important thing is the 120V (inside the junction box) is physically separated from the low voltage (what you can see). . but rather a box cover with knockout like this one: . That looks to me like a transformer built into a junction box cover. That is a thing. – Harper . I took the lock nuts off the transformer and just screwed the boxes on directly. However, I can't screw the boxes on tightly or they'll be at odd angles. The transformer is deeper than the boxes. This means that the boxes just .The problem I see with this is mixing voltages inside of a junction box. Usually if there are two different voltages in a box, code requires a divider to separate them. This is also why most doorbell transformers have the line voltage wires inside of a box and the low voltage wires sitting outside of the box on the other end of the transformer. A more elegant solution would be to do it electrically w/ a relay. Unfortunately, I'm not sure where to begin on that. My thought was to have a single pole switch to a logic terminal telling the VFD to use motor one or two. 24V = motor one, open circuit = motor 2.
I have a question similar, but not identical to this one: Transformer location. Can I install a 24V transformer inside of interior wall cavities, with no access other than removing drywall? My house is a split-level ranch with 5 heating zones. As a split-level, it has no basement, ie the ground floor is on a slab. The boiler is in the garage. It has a what appears to be a 1/2 inch knockout hole on the side which is where the original transformer was attached via a locknut. Can the new 24v transformer be attached to the existing 1/2 inch knockout hole in the plastic box safely? The new transformer (the only one available) is the screw attachment type not the locknut type.
@harper based on the original install and the proper connection to a box for the new transformer, I would say the new one is much better because of the mounting method under the NEC or not, because the original install did not meet the NEC or close in any way the one linked two at least has separate zones for mains voltage and low voltage as required by code.
@nobody isn't the low-voltage side completely made of wraps of insulated wire? If so, how would external current get to the secondary wiring? Such transformers provide a galvanic isolation from the grid, so the only apparent voltage would be +/- 24v, which isn't typically considered dangerous, though with wet hands you might feel it. Most also have thermal one . Installing the Junction Box for Multiple Pendant Lights. Bear in mind that the junction box is the central hub for wiring multiple pendant lights. Choosing a strategic location is crucial, typically the center spot of where all lights will hang. First, fasten the junction box to a reliable support.
Simply get your new cable into the box with the power off (use one of the built-in NM clamps you can see on the bottom right), then connect black to blacks, white to whites (+a black from the transformer), and bare to bares/greens.
