Please note: You do not need to purchase an additional sensor for a single phase household as one sensor already comes with the OWL Energy Monitor. Additional sensors are only required for two and three phase systems.
If you have a two or a three phase system you will require additional sensors for your energy saving Owl monitor. You will need one extra sensor for a two phase system and two extra sensors for a three phase system.
The Standard Owl energy meter sensors are rated up to 70 amps and can be used on cable up to 11mm in diameter.
The Large< Owl energy meter sensors are rated up to 200 amps and can be used on cable up to 17mm in diameter.
