Immersed grounding strips & accessories

Implementation

In its typical application, the HStrip^TM is mounted below the waterline and directly below a Siedarc^TM electrode, and connected to a loop conductor surrounding the boat at about deck level, as shown in this photo of a recent installation on an Outbound 46. The GapCon^TM air gap can be added to isolate the grounding strip to minimize galvanic currents, and two HStrips can be installed end-to-end connected by the HStripCon^TM to provide one square foot contact surface at one location.

HStrip^TM 0.5 ft² immersed grounding strip

HStrip^TM with bolt connections	Description 0.5 ft^2 tinned copper grounding strip for immersed water terminal with standard bolt connections. Two heavy duty tinned copper lugs are included. Dimensions are 3/16"x2"x 36". Estimated DC resistance in salt water is 0.29 ohms. Note that a square 1 ft^2 plate in salt water has a ground resistance of 0.36 ohms.
	Use & installation The HStrip^TM is supplied with two round-head tinned brass screw through bolts for attachment and electrical connection. The round head on each bolt increases attachment security. Electrical connection point is to either or both of the two bolts. Two HStrips are recommended to give a total immersed area of one square foot. Use the HStripCon^TM below for connecting end-to-end. A spark gap can be added for galvanic isolation. See GapCon^TM below.
