How to install
In most cases you can fit the sensor clamps at the meter board yourself. When this is not possible it’s a quick (5 minute) job for an electrician. If, unlike the examples below, your installation requires you to go behind the meter board, you must use an electrician.
The example on the left is a single phase house with a ‘mechanical’ style meter. The example on the right is a three phase house with ‘smart’ meters installed.
