In the 120V circuits of homes and offices, the grounded conductor is the same as the neutral. Typically, when wiring a switch for a 120V load (e.g., a light) only one wire comes to the switch and only ...

Ever found yourself tangled in a mess of wires and components, struggling to create a clear and intuitive wiring diagram? If so, you’re not alone. Many electronics enthusiasts face this challenge, ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...

I was reading up on a project and came across this link. It mentions that if a light fixture is between the switch and the panel it is common to switch the white and black wires to the right of the ...

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match. Ground-fault protection and the multi-wire branch circuit ...

This article discusses many common misunderstandings about the function of the neutral wire and its relation to power problems. The subjects of dedicated lines, phase reversal, isolation transformers, ...

Most smart switches require a neutral (white) wire to maintain a Wi-Fi connection, but if your home was built before 1985 (or thereabouts), this might not be an option. If you fall into the latter ...
