7.6 Meter and CT connection
The current Transformer, also called CT, is usually installed on the L wires between the house loads and the power grid.
The Meter can be installed in the AC combiner box or other places that are unable to be touched by children.
Wattsonic CT cable with a length of 2m is fixed and can’t be extended.
The CTs have been connected to the Wattsonic Meter when you received them, and you just need to follow the wiring
diagram in the Meter to join the CT.
