Single-phase and three-phase: two modes of electric current to know

Single-phase and three-phase are the connection methods found in homes. They correspond to two forms of current (alternating current and direct current). To understand these two modes of electric current, you would again have to resort to your first technology courses which spoke of these two forms of current. Instead of speaking of "plus" pole and "minus" pole, we will rather speak here of "phase" and "neutral". The phase supplies your appliances with electricity, while the neutral distributes it evenly. This balance is essential for the safety of your installations. Single-phase current consists of a single electrical phase. On the other hand, the three-phase current consists of 3 electrical phases. It is useful to know these concepts well in order to be able to choose three-phase or single-phase for your electrical and lighting installation.

What are the differences between single-phase and three-phase current?
The difference between single phase and three phase is not only in the components, but also in the operation.

single-phase current

For a single-phase current, when you look closely at the connections, there are two cables: the neutral cable (often in blue) and the phase conductor (usually in red or black). The single-phase connection passes electrical current through a single phase wire. The voltage difference between the phase wire and the electric wire is 230 volts. Single-phase current is most suitable for domestic applications. Most appliances (vacuum cleaner, oven, bedside lamps or others) are marked 230 volts. Single-phase current is a form of alternating current.

The three-phase current

For a three-phase current, 4 wires arrive at your home (three phase wires and a neutral wire). The current which passes between the three phases is sinusoidal. Unlike single-phase current where the voltage is 230 volts, that of three-phase current is 400 volts. The main difference between single-phase and three-phase is relative to the power of current that the electrical outlet is able to collect. The electrical outlet that characterizes the three-phase current consists of a flattened-shaped hole and three or four round-shaped holes. Three-phase current is a form of direct current electricity.
