Earth Cable: The Ultimate FAQ Guide

1. What is Earth Cable?

The earth cable refers to wire within the electric circuit that provides a safe pathway to the ground for excess current in case of an electric fault.

2. Is Earth Cable and Ground Wire the same?

Yes. Earth cable is the same as ground wire.

3. What is the Purpose of Earth Cable?

The purpose of the earth cable includes:

  • To Providesafety to a power plant and electrical equipment.
  • Shutting off power when there is an inconsistency in the current flow
  • Neutralising lighting strikes during lightning.

4. Why do you need Earth Cable?

The earth cable is essential in preventing electric shock that can occur when a live wire touches the metal casing of electrical equipment.

5. What is the difference between Earth Cable, Neutral Cable and Live Cable?

  • The function of a live cable is to carry electric current to the electrical equipment. It is usually red, blue or yellow. You will find all the interruptions to the current such as the switch or fuse along this cable.
  • The neutral cable usually has zero volts and completes the current circuit of an electrical device. It offers a pathway for the current to flow back to the mains. Its insulating material is black.
  • The earth cable or ground cable is a cable that has little resistance. You can locate it on the metal casting of your electrical equipment. Its function is to break the current in case of an electrical fault. It is green and yellow.

At any given time, choose high quality power cable for optimal performance.

6. What is the Recommended Color Coding for Earth Cable?

Cable color coding

Cable color coding

The recommended color coding for earth cable is green with yellow stripes.

7. Earth Cable should conform to which Quality Standards?

Earth cables should conform to the following quality standards:

  • IEC standard
  • EN50173 standards
  • Telecommunications Industry Association (TIA) standards

8. How does Twin Cable and Earth Cable compare?

A twin cable is a type of cable consisting of the live and neutral cables alone.

The function of the twin cable is to supply current to the electrical equipment and to ensure the current is complete.

The earth cable breaks of the circuit in case of an electrical fault, thus protecting the electrical equipment.

A twin and earth cable is a cable consisting of two insulated wires, the neutral and live wires and a bare earth or ground wire.

9. What is a 3-core and Earth Cable?

A 3-core and earth cable is a cable consisting of three insulated cables and one bare cable covered by a PVC outer sheath.

The three insulated cables are black, brown and grey

It is a low smoke cable suitable for use fire risk applications or in offices where there is high traffic of people such as in offices.

The cable is resistant for use to humidity hence ideal for use in humid and dry areas.

10. Does Earth Cable have recommended Operating Voltage Range?

There is no recommended operating voltage range for earth cables.

The operating voltage will depend on the voltage range of your circuit.

11. What are the Characteristics of Earth Cable?

Earth cables have the following characteristics:

  • They have a low resistance
  • Good electrical conductivity
  • Excellent corrosion resistance
  • Good equipotential bonding characteristics
  • Durable
  • Ability to withstand high fault current

12. Why use Stranded Tinned Copper Wire in Earth Cable?

The stranded tinned copper wire present in earth cables helps in resisting corrosion extending the durability of the earth cable.

13. Do Earth Cables have Insulation Material? What is the best Insulation Material for Earth Cable?


Certain earth cables have an insulation material which is usually yellow with green stripes.

The best insulation material for earth cable include:

· Polyvinyl Chloride (PVC)

It is the commonly used insulation material due to their durability, and they are relatively cheaper.

However, the availability of chlorine in the PVC makes it a health hazard, especially when burning the material.

Its operating temperature ranges between 75C and 105C depending on the type of PVC.


XLPE offers a low dielectric property when you compare to PVC.

It is also moisture-sensitive when you use it under low voltage. As a result, it is best for high voltage.

· Thermoplastic Rubber

Thermoplastic rubber offers a variety of coloring option as an insulation material for your EMC cables.

They also offer a wide range of operating temperatures and a high curing ability.

14. What is the difference between Short Circuit and Ground Fault?

A short circuit refers to the exposure of wire, causing it to touch another wire.

This is the case when a hot wire touches a neutral wire causing a short circuit.

When this happens, there is a flow of large current amount through the fuse resulting in a circuit to break.

A ground fault results when a hot wire touches the ground wire when this happens, a large amount of current flows through the fuse resulting in the fuse to blow.

15. What are the General Requirements for Earthing?

The general requirements for earthing need to include the following;

  • Earth electrode including the earth electrode ring type and an alternative earth electrode
  • Main earth bars or terminals
  • Protective conductors
  • Equipotential bonding conductors including supplementary and equipotential bonding
  • Good corrosion resistance
  • Low ground impedance and resistance. It should be less than 1 ohm of resistance.
  • High fault current resistance

16. What is the difference between Bonding and Earthing?

Bonding refers to connecting two or more electrical conductors using a metallic conductor.

The purpose of bonding is to ensure that the conductors carry equal electrical potential.

Bonding also reduces the impedance pathway back to the mains.

Earthing refers to connection of a conductive object to an earth cable.

This is by connecting the neutral conductor to the earth conductor.

The essence of earthing is to prevent the occurrence of an electrical fault.

17. What are Electrical Grounding Techniques?

The following are the electrical grounding techniques:

  • Earthing mats involves the use of several rods joined through copper conductors reducing the overall resistance. Is common where there is a large fault current.
  • Earthing electrode involves the insertion of any pipe, wire or plate horizontally or vertically to the ground.
  • Pipe earthing is a common earthing method involving a perforated pipe and a galvanized steel. You place it in a permanent wet soil uprightly.
  • Plate earthing involves burying galvanized iron or copper of given dimensions into the ground
  • Earthing via water mains where there is a connection ofcopper wire to water mains using a steel binding wire.

18. How do you Test Quality of Earth Cable?

You use a multimeter to test the quality of an earth cable.

A quality earth cable should not have any current passing through it before installation.

The resistance of an earth cable should be zero ohms.

19. How does Earth Cable Work?

The earth cable works by offering a pathway for the electric current to pass through to the ground in case of an electrical fault.

Earth cable is generally on the metal case of the electrical appliance and has zero resistance.
