Article 694
Although all metal components that can
potentially be energized are required to be
grounded, Article 694 exempts the blades and
tail from this requirement, as there is no electrical energizing source associated with them. In
It should always be assumed
that a spinning turbine is
generating electricity.
addition, since the guy cables on a guyed tower
are physically connected to the tower, these are
assumed to be grounded through the tower per
Article 694. Regardless, for lightning protection
purposes, most installers will ground the guy
cables to a dedicated ground rod at each respec-
tive anchor. Another best practice is to bond all
guy anchor ground rods together with a ground
wire, then run this wire back to the tower and on
into the house where the system electronics are
housed. Again, this puts everything at the same
electrical potential.
