| + | [* black] Extremely thick copper wires allow the meter to be wired in series with a household's main power supply. They're capable of handling 200 Amps! |
| [* black] Interestingly, the meter relies on a black ring-shaped current transformer installed around the copper wires to send power consumption signals to the main board. | |
| [* icon_note] [link|http://en.wikipedia.org/wiki/Transformer#Instrument_transformers|Current transformers] indirectly measure the current flowing through the thick copper conductors and provide an output that can be read by the electronics on the board. | |
| [* black] Long metal pressure contacts along the inside case of the meter conduct 240V AC electricity to pads that provide power to the main board. |
