What electricity do I have in my home? Single-phase? Or is it three-phase? What are the differences? Which should I have?
You have probably asked yourself some of these questions before, or all of them, while checking your bill or trying to calculate the power required in your home.
We will answer all your questions once and for all.
What is a three-phase installation?
This is the system used in most houses and apartments.
These systems use a single phase and a single alternating current. Their normalised tensions are established at 220 or 230 volts and hence a maximum contracted power of 13,86 kW for 220 volts and 14,49 kW for 230 volts.
These systems are normally used in households and the size of the house is irrelevant, since a detached house with a swimming pool can have a single-phase system without any problem.
If you want to find out if you are single-phase, check your electrical panel in your house (normally next to the front door).
If it looks like this (a double device), it means your system is single-phase:
