Reinforcing Steel Lead Wire Installation

Connections were made to three steel reinforcing bars (rebars) near the edges of each ICCP grid area. Two connections were made to longitudinal rebars. The other connection was to a transverse rebar. The connections were checked for good continuity within the entire bottom layer of reinforcing steel. The contractor accessed the rebars by drilling a 2-inch (5 cm) diameter hole through the concrete cover. Number 12 AWG (2.7 mm diameter) copper conductor lead wires were welded to the reinforcing steel at the access holes (Figure 38).

 

The rebar lead connection access hole was grouted with Sikatop 123 Plus? (Figure 39). The rebar lead wire was routed in 1-inch (2.5 cm) conduit beginning where the wire emerged from the concrete to the edge of the area where they teed into the conduit containing the anode lead wires. At the tees, the three rebar lead wires from each area were soldered to a single Number 12 AWG (2.7 mm diameter) copper conductor that serves as a cathode bus. The bus was placed in the 2-inch PVC conduit containing the anode leads and ran to the junction boxes. All wire-to-wire connections were solder joints that were sealed watertight.
