Final answer:
This statement is b. False. The ground wire should not always be clamped upstream of the water meter.
Step-by-step explanation:
The ground wire should not always be clamped upstream of the water meter. This statement is False.
The ground wire is used in electrical systems to provide a safe path for electric current to flow into the ground, in case of a fault or short circuit. In a three-wire system, the neutral wire is connected to the earth at the voltage source and user location, forcing it to be at zero volts and supplying an alternative return path for the current through the earth.
Grounding the water meter can create a hazardous situation as the water pipes are often made of conductive material, and grounding the water meter can allow electrical current to flow through the pipes, posing a risk of electric shock and damaging the plumbing system.
