If you’re obsessed with saving energy and feel a compulsion to control every kilowatt of power consumed in your household than this may be the product for you. The TED is a complete, electricity monitoring system that shows you your power usage numbers in real-time. Designed for a typical North American residence with a single 200-amp (max) service panel. The system comes complete with all you will need to get accurate, up-to-the-second energy data.
I would suggest you get an electrician to install this on your power grid or fuse box though the company says the unit can be installed by a “qualified” homeowner.
