Earthing and bonding are two terms very closely related but are different. Even though earthing and bonding are meant to prevent electric shock, they have a subtle difference that needs to be understood. This article explains the concepts and the difference between earthing and bonding. Note: The...
Explaining difference between bonding, grounding and earthing, micro difference, illegal practice of interchange purpose of grounding
Knowing the difference between grounding, bonding and earthing is imperative to properly design and install an electrical grounding system. But first, let’s define the terms. Ground: A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth,...
The term Bonded (Bonding) is by definition “connected to establish electrical continuity and conductivity.” Ground by definition is “the earth” and Grounded (Grounding) by definition is “connected (connecting) to ground or to a conductive body that extends the ground connection.” Equipment-...
National Electrical Code Section 250.168 Bonding Jumpers Install an unspliced bonding jumper to connect the grounded conductor and the equipment grounding conductor in grounded direct-current systems. Make the connection at the source or the first disconnecting means where the system is grounded. ...
Bonding means connecting objects together. A separately derived system must be grounded to earth at the source. All non-current-carrying metal parts and equipment must be bonded to the grounding point of the derived system. Bonding of metal equipment provides an effective ground-fault current path...
