1. A method for corrosion protection of a metal section in a cast body of an ionically conductive concrete or mortar material comprising:
providing an anode assembly comprising:
an impressed current anode; and
a sacrificial anode of a material which is less noble than the metal section;
maintaining the impressed current anode electrically separated from the sacrificial anode to prevent direct electrical communication therebetween;
prior to installation, positioning the impressed current anode and the sacrificial anode into
installing the [ common ] assembly, while the impressed current anode and said sacrificial anode are at said fixed positions, in contact with the cast body of ionically conductive concrete or mortar material so as to locate the impressed current anode in ionic contact with the cast body of ionically conductive concrete or mortar material and so as to locate the sacrificial anode in ionic contact with the cast body of ionically conductive concrete or mortar material;
providing a DC power supply having a first pole and a second pole; the [ common ] assembly including [ a first ] electrical connecting
providing a connection by the [ first ] electrical connecting
providing a connection of the second pole of the DC power supply to the metal section; and
providing a connection [ by the second electrical component ] of the sacrificial anode to the metal section;
so that the impressed current anode by [ a ] current from the DC power supply provides the corrosion protection of the metal section;
and when the DC power supply [ or impressed current anode ] is not
