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 not be extended.
The CTs were connected to the Wattsonic Meter when you received them, and you need to follow the wiring diagram in
the Meter to join the CT.
