Wow, now that I see your picture, this thing is a hatchet job. No, no. That transformer cannot just be stuffed loose in a plastic (!!) Box. There is no separation between mains and low voltage. What a fiasco. I would extract the doorbell wiring from the box and bring it out to the wall through a hole outside the box. Now, with only mains wiring in ...

No. Electricity travels in loops. If you don't have a loop, it will just sit there. In mains electricity (which I assumed we're talking about here since that's what we do in a home improvement stack), if you somehow manage to ground any of that, you'll get a big bang poof until something burns, blows, or trips. Now that I see your edit, I see more ...

The problem you have is that your current switch is wired as a switch loop. This means that a hot lead comes into the switch box and a switched hot lead leaves the box. There is no neutral wire in a true switch loop. Commonly a white wire is used for the line to the switch, but it is supposed to be marked with black tape or a marker to indicate it is hot. ...

Refrigerant cycle dehumidifiers have some sensitivities, and I would recommend operating in accordance with the manufacturers recommendations. I operated several types of conventional and LGR commercial grade dehumidifiers for many years. I don't know what your machine needs, but there were several reasons why our machines needed to be operated properly. ...

Older security systems use normally closed switches on doors and windows. They use a magnet and a reed switch to keep the circuit closed. Then the circuit has a small amount current continuously flowing to monitor the circuit. The resistor is to limit the amount of current flow. If the door or window is opened, then the alarm goes off. If a burglar cuts a ...

Keep 'em separated Since you have two subpanels feeding this setup (one for each "side"/half), you'll need to make sure that the switches for each side have a neutral return back to the corresponding subpanel, and only the corresponding subpanel. In other words, the two left-side switches have a neutral wire going back to the left-side subpanel, and the ...

Use a bridge rectifier and a LM2956 module to make 5VDC from the 24VAC supply.

The way house wiring is done in practice one cannot simply wrap an insulation piercing tap around a wire and get power. This is done all the time in cars, but not in houses. If a wire in the attic happened to be passing over the center of a room where you wanted a ceiling fixture, code and practice do not allow a simple tap. Nevertheless, it is easy to get ...
