When electrical appliances in your home increase, your home would require more electricity to run them all – when the sum of wattage of all electrical appliances you use at a given point of time exceeds 7.5kW, you need a 3-phase connection. For instance, if you have three or more air conditioners in your home, you should upgrade to a 3-phase power supply – it will enhance the reliability and stability of the power supply.
Electricity gets connected at a single-phase (230 and 240 volts) or 3-phase (400 and 415 volts). A 3-phase circuit merges three alternating currents of the identical frequency that generates three separate waves of electric power, so the power supply will never drop to zero, keeping the electric supply constant.
In the following instances, you will need a 3-phase power supply in your home.
Older homes will often run into a situation where they will need a 3-phase power supply. Besides, if you have three-phase equipment running in your home and only have a single-phase system, you need to upgrade your electricity supply to a 3-phase. Upgrading your power system will guarantee that your electric equipment runs seamlessly.

With a 3-phase power, you can safely use all your electrical appliances, at the same time, without any botheration about them tripping the circuits. However, you will need a 3-phase power supply only when you have more electrical appliances to run – for instance, three or more air conditioners along with all other residential electrical appliances.
A 3-phase circuit supplies more power density than a single-phase circuit at the same amperage; thus, it can curtail the wiring size and costs. Besides, a 3-phase power supply can balance loads seamlessly, decreasing harmonic currents and the requirement for large neutral wires.
A 3-phase electric power supply needs less conductor volume for the same voltage and overall power than a 2-phase 4-wire circuit of the same transmitting capacity.
Changing your connection from a single-phase to 3-phase won’t increase your electricity charges. The electricity units you use will remain the same, as they are based on the wattage of your electric appliances and not on the type of electricity connection.
The cost to upgrade from a single-phase to a 3-phase service is between $8 to $11 per linear foot, provided it connects from the nearest existing 3-phase power line in the neighbourhood.
Go to your meter box and glance at the ‘Main Switch’ or ‘Supply Main Switch’ on your switchboard. If the switch resembles three switches merged into one and is broader than 3 centimetres, you have 3-phase power. Conversely, if it is a single switch and thin, you have a single-phase power.
