Difference Between Bonding and Grounding

Bonding is a process that is performed by connecting a non-current carrying metal or objects. These metals are bonded at the same value or bonding level, which have the same electrical potential as the electrical parts.

Grounding is a process that connects an electrical system to earth in a way that will restrict the voltage produced by lightning, line rushes, or accidental connection with higher-voltage lines, and that will maintain the voltage to earth through a normal process.

Parameters of ComparisonBondingGrounding
DefinitionBonding is the process of securing fusible pieces to establish a conducting route. Grounding is any voluntary or unexpected connection between an electrical course or device and the ground.
GuaranteeBonding guarantees reliable electrical connection of the electrical distribution system of the house. while Grounding warrants that all metal components of an electrical circuit that an individual might reach are attached to the earth, guaranteeing zero voltage.
PerformanceBonding is obtained by utilising a wire. Grounding is performed and done by practising a rod.
UsageBonding produces protection through lapse current.Grounding to the surface has no substantial influence on the performance of the electrical usage.
ProtectionBonding separately does not offer protection but connects the electrical current to the metal parts properly.Grounding makes sure that electrical energy is contained and protected from accidental touch.

What is Bonding?

The process of Bonding is performed by the application of an ordinarily non-current-carrying conductor to attach devices to keep them at an equal voltage.

Bonding these types of equipment together will limit possible electrocution if a person touches two separate parts of pool supplies at the same time if one of those pieces of equipment happened to be at a different voltage than the other.

In regards to the house electrical system, bonding forms a way for ground-fault current to move back to the panel to free the fault. To say differently, bonding gives a pathway for the electric current to pass through a breaker if a piece of faulty or damaged devices is secured in place. 

What is Grounding?

Grounding is a process that is used for connecting the active part, which means the piece which provides electric current following standard state through the earth, for instance, inactive part of the power parts.

There are a few causes of problems in electrical distribution system wires, and these may be because of thunderbolt, line faults, or accidental connection with different high voltage lines, precariously high voltages can originate in the electrical circulation mode wires.

Some sort of black wires is commonly in this type of grounding processes. Every type of electronic circuits, which are AC & DC currents, require a source zero volts potential which is known as the ground in electrical engineering terms to make plausible the electrical current run from the generator to load.

Main Differences Between Bonding and Grounding

  1. Bonding produces protection through lapse current, and grounding to the surface has no substantial influence on the performance of the electrical usage.
  2. Bonding separately does not handle protecting something, but if one of the cases is grounded, electrical energy stock up is not probable.


Whether it is a grounding fastening or bonding joint, the sole purpose in electrifying a house is to have no pieces of metal cases or other conductive elements next to the lines because this could be a potential shock risk.

The best wager that can be taken to be protected from loose electrical wires or potential electrical shocks is to have the electrical systems grounded so that there are zero chances of accidental shocks.
