There is something that I do not understand
At one point you say:
"Linking meter to the street power network"
Then you say:
"This work is allowed since it is a community consortium and they only have a single meter for all the houses and the meter to be placed would be to know how much you have to pay per house until the procedures carried out by those in charge of the cooperative"
In that case, the new meter should not be connected to the street network but provisionally to the corresponding housing line
Casas era would be the installation and assembly of pilaster with meter and thermal and the energization of said to the network of houses
