Difference Between Bonding and Grounding (With Table)

Bonding and Grounding are methods that fasten metallic parts to the conducting pathway, which are a means of protection from electricity connection. While Bonding and Grounding are terms that are mostly used interchangeably, but Bonding is a process used as a protection from electric shocks, whereas Grounding is a process that metal parts are connected to the ground. 

Bonding vs Grounding

The difference between Bonding and Grounding is that Bonding is a method that pulls away from the conducting electrical energy with the help of metallic parts that are utilised for the bonding connection, which protects an individual from electrical shocks. Meanwhile, Grounding is a method that is performed to make sure that the electrical parts are connected to the ground. 

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. The voltage parts are bonded at the same levels because if the voltage levels are incompatible because this might result in fatal electric shocks.

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. Voltage spikes because of foreign causes will result in electrical damages.

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. An illustration of this is any swimming pool devices that must be electrically bonded mutually so that all devices, like pumps and radiators, will be at an identical 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. When they are properly bonded, they cannot be at different voltages.

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. Grounding is a process for the assurance of protection from the power usage devices and to provide an adequate recovery way from the device to the power origin.

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. Grounding produces a safe, substitute way about the electrical usage of your house, thus reducing cost from these type of accidents.

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. Within an Electrical Power system, it is grounded at the distribution point or consumer end, but it is not earthed in Automobile parts. For example, all vehicles’ electrical circuitry have ground attached to the body and metallic frame that are protected from the ground by tires.

Main Differences Between Bonding and Grounding

  1. Bonding is the process of securing fusible pieces to establish a conducting route. Meanwhile, grounding is any voluntary or unexpected connection between an electrical course or device and the ground.
  2. Bonding guarantees reliable electrical connection, while grounding warrants that all metal components of an electrical circuit that an individual might reach are attached to the earth, therefore guaranteeing zero voltage.
  3. Bonding is obtained by utilising a wire, whereas grounding is performed and done by practising a rod.
  4. Bonding produces protection through lapse current, and grounding to the surface has no substantial influence on the performance of the electrical usage.
  5. Bonding separately does not handle protecting something, but if one of the cases is grounded, electrical energy stock up is not probable.

Conclusão

In conclusion, everyone usually ends up getting involved in both grounding and bonding and being the same thing. 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.
