There are a few factors to consider when installing a prepaid meter.

You will need to choose between a single-phase and three-phase meter before installation. The number of meters you install will depend on how big the property is.

Here’s how to install a prepaid meter


Before we continue, it is recommended that you hire a professional to install your prepaid meter. The installation will differ in each building as it will depend on whether it is a free-standing home or a larger building with individual units. 

Freestanding home

A freestanding home with a single building will require one prepaid meter. The preferable place to install the meter would be between the municipal board and the distribution board of the home.

A home with a cottage is slightly more complicated as two meters are required. The meter should still be placed between the municipal board and the distribution board of each home; however, there need to be two isolator switches placed between each of the prepaid meters and the municipal board.

Building with units

A building with multiple units will have a similar installation to a home with a cottage, with additional meters and isolator switches. Typically, an existing building will already have unit meters in place – though it is not required – the prepaid meter should be placed between the unit meter and the unit distribution board.

If the building is new, the units may not have their own meters and so the prepaid meters should be placed between the municipal board and distribution board of each unit.
