This 80 Amp electricity sub meter is ideal for use in locations where you would like to know how much electricity is used by individual single phase circuits such as:
- Electric vehicle / electric car charger monitoring
- Granny flat
- Workshop
- Dedicated single circuit (air conditioning, electric hot water, pool, spa, cool room, etc)
- Checking electricity use at a sub-board when the utility meter is far away or not easily accessed.
