Grounding System

What type of grounding it is if the earth ground is connected to the

neutral points of current carrying conductor of a transformer or other

machines?

• Earth grounding

• Equipment grounding

• Ground fault

• System grounding

What type of grounding it is if the earth ground is connected to non-conducted materials such as conduit, cable tray?

• Earth grounding

• Equipment grounding

• Ground fault

• System grounding

What Is a Good Ground Resistance Value?

• Zero ohm

• Less than 5 ohm

• 5 ohms

• More than 5 ohms

What is the minimum depth of a ground rod according to the NEC?

• 4 Feet

• 6 Feet

• 8 Feet

• 10 Feet

How do we call the connection of ground wire to the ground rod?

• Bonding

• Grounding

• Soldering

• Welding

How do we call the electrical system’s connection to the ground itself?

• Bonding

• Grounding

• Soldering

• Welding

What type of grounding is for the purpose of controlling the voltage to earth, or ground, within predictable limits?

• Earth grounding

• Equipment grounding

• Ground fault

• System grounding

What method of grounding is used to measure the resistance-to-ground of existing grounding systems?

• Oscilating Voltage

• Fall of Potential

• Clamp On

• Ground Resistance Monitoring

What method of grounding is for measuring the resistance-to-ground of a grounding system or electrode?

• Oscilating Voltage

• Fall of Potential

• Clamp On

• Ground Resistance Monitoring

It is induced into the grounding system at a point where it will be forced into the soil and return through the utility neutral.

• Oscilating Voltage

• Fall of Potential

• Clamp On

• Ground Resistance Monitoring
