What is a three phase electricity meter?

Three phase (3 phase) electricity supplies are more efficient than a single phase supply and are seen as the ideal choice for commercial environments that run machinery which requires a larger amount of electricity.

Converting to 3 phase electricity

For small organisations that use small amounts of electricity, a single-phase installation is usually the most suitable. However, for businesses that use large amounts of energy, a 3 phase supply allows you to have cheaper wiring and lower voltages, making it much a safer and cost-effective option within a commercial environment.

Can I install 3 phase electricity at home?

If you require more power in your home, Crown Utilities can disconnect your current single-phase connection and install a new 3-phase connection. A domestic property would typically require an upgrade from single-phase to 3-phase due to a flat conversion, or an increase of large electrical appliances or facilities, such as a water or heat pump, a stair lift, or an at-home EV charger.

If you already have a standard electricity connection, we can disconnect this and provide the new connection for a 3-phase electricity supply.

How do you know if you have 3 phase power?

The best way to determine whether you have a single or 3 phase connection is to contact Crown Utilities who will be able to tell you without a doubt the connection type you have. We have a team of experts who are specialists in the field who can advise you on the best electrical meter for your requirements.

Alternatively, you can look at your electrical fuse or supply; a single-phase supply generally has one fuse, and a three phase supply has three 100amp fuses.

What is the difference between single-phase and three-phase?

Both three phase and single phase refer to electricity supplies, however, what tells them apart is the amount of power; a single phase supply is smaller than a three phase supply.

There are also several differences in the way the electrical current is set up, only a single wire is required to connect the circuit for single-phase, whereas a 3 phase supply requires 3 wires. The voltage is greatly increased on a 3 phase connection, single-phase voltage is 230v but a larger 415v on 3-phase connections.

What are the benefits of having a 3 phase electricity supply?

3 phase supplies are beneficial for larger business that use large amounts of electricity as they provide more power than single phase meters. They are becoming increasingly popular in organisations such as data centres as they are highly efficient and allow machinery and equipment to reliably run on this type of supply.

A three phase meter allows you to measure your electrical consumption in kWh and usually has up to three meters or one large single meter with cables directly wired into it.
