#No neutral smart switch code#
While this will be vastly different depending on where you live, the electrical code in North America has generally been changed in recent history to require a neutral wire in light switch boxes. This is just a very simple one Why is my switch missing a neutral wire? All electrical circuits have a return path The neutral wire is as important as the hot wire, they function together as a pair to power things, and both are needed for the light to turn on. The colour is typically white or grey in North America, but there are a lot of different regulations depending on your region, so be sure to check what your local laws are. To power a lamp, two wires will come from the wall into the fixture that will connect these wires to the bulb via a socket. This is why plugs have two main prongs, the third being a safety mechanism called ground or earth, which is not the same as the neutral wire. An electrical circuit will always have two wires going to and from equipment needing to be powered. The neutral wire is the electricity's return path after it has entered a load, which is a fancy way of saying any device that uses power.
Do not attempt anything you are not trained to do and always consult with a licensed electrician before any work. Warning! Electrical work can be dangerous, and if done incorrectly, could have fatal consequences.
