on video 120V 240V Electricity explained - Split phase 3 wire electrician

 



120V / 240V Split Phase residential electrical supply. In this video we're going to be learning how split phase electricity supplies work to get both 120V and 240 Volts. We'll look at how the electricity gets from the power station and to the property and then how it is connected around the house and each of the main components.

This system is used in North America so we'll use their terminology and color coding. If you're from outside this region then you can still follow along but your electrical system works differently, we've covered this in a separate tutorial, do check that out here.

Warning
Remember electricity is dangerous and can be fatal, you should be qualified and competent to carry out any electrical work. Never work on hot/live electrical circuits.

So electricity is generated at the power station which is usually located far away. The power station generates AC alternating current and is connected to a step up transformer, this transformer increases the voltage to reduce losses and is connected to the grid. The grid carries high voltage electricity over long distances to towns and cities.

Once it reaches the towns and cities it will enter a step down transformer which will decrease the voltage to a safer level. From here it will be distributed locally into smaller circuits on different streets or groups of properties.
