The jumper wire is actually a grounding wire a short section of large gauge wire that jumps or goes across the water meter and is securely attached to the water pipe at each side.
Water meter grounding jumper wire.
In the video i talk about why water pipes need to be grounded.
For 200 amp service use a 4 gauge copper wire from the panel to the water pipe within 5 feet of where it enters the house and also between where it enters and the meter.
For 200 ampere.

Residential water heater use.
The blackburn water heater grounding kit comes with two brass ground clamps.
This sub feed cable will have 2 insulated power conductors 1 insulated neutral conductor and one ground wire.
The ground wire is bonded at the main panel to the ground system.
Missing jumper wire at water meter is a common electrical defect and safety hazard noted in many home inspections for older homes.
According to national electrical code the water piping must be bonded to the service equipment enclosure the grounded conductor at the service service neutral the grounding electrode conductor where large enough or directly to one or more of the grounding electrodes.
Product can be used with residential water heaters.
Still there are electricians and local building codes that vigorously defend the water heater bonding wire as a proper safety measure.
This is from a different table of sizes for grounding electrode conductors as opposed to ground wires from main panel to subpanel grounding conductors.

Copper conductor 6 awg included.
Sub panels are grounded through the cable that provides the sub feed circuit power.
If you use your home s main water pipe to ground the electrical system and many homes do you should attach a jumper wire around the water meter in order to provide a better path for the electricity ground path.
Kit includes two brass ground clamps and copper conductor.
This bonding is essential to maintain continuous ground path.
If no jumper wire is installed a surge in electricity could cause damage to the water meter in some cases.
Brass ground clamps included.
The reasoning is that the metal casing on the water heater itself is thought to be sufficient to complete the continuous grounding path between the cold water and hot water pipes in the home.
The bonding jumper is to be sized using table 250 66.
Grounding a sub panel.
