If you have a ring earth electrode and you have it used for the lightning protection installation, you can join the rim and lead out the wire (hoop iron) to the equipotential bar in the house, but the connection of this wire must be done underground. It is not allowed to attach to the discharge wire above the ground, because the lightning current, when it hits the lightning protection system, may partially penetrate into the building through the grounding conductor of the equalizing rail during discharge to the ground.
So all ground connections are made underground
