Earthing & Earth Bonding

Why Earthing & Bonding?

  • Earthing and bonding are very important parts of an electrical installation. They are designed to reduce the risk of electric shock and help ensure that protective devices operate correctly if an electrical fault occurs.
  • If you have had a gas meter change, the gas installer may have advised you to have the earth bonding checked and perhaps left a notice near your gas meter to remind you.

Earthing

  • Earthing provides a safe path for fault current to flow back to the source of the electrical supply. For example, if a fault occurs inside a metal-bodied appliance such as a washing machine, the metal casing could potentially become live.  Without an effective earthing arrangement, a fault could remain undetected and a person touching the faulty appliance could provide a path for the current to flow to earth through their body.

Earth Bonding

  • Bonding has a different purpose. It connects metallic services entering a property, such as water or gas pipes, to the installation's main earthing terminal. The purpose is to reduce the difference in voltage that could occur between different metalwork during an electrical fault. . This reduces the risk of a person receiving an electric shock by touching two metal parts that are at significantly different voltages. 

Keeping You Safe

Older properties may often have inadequate or outdated earthing and bonding . Problems can include main earthing with high loop reading, and missing or undersized main bonding conductors. 

Good earthing and bonding arrangements are fundamental to electrical safety. If you are having electrical alterations or additions carried out, the existing earthing and bonding arrangements should be checked to ensure that they are adequate for the proposed work. 

Have it Checked!

If you are unsure whether the earthing or bonding in your property is adequate, Alan Davies Electrical can inspect and test your electrical installation and advise you if any improvements are required. Whether you are concerned about an older installation, arranging an EICR, or simply want reassurance that your property's electrical system is safe, professional inspection can identify problems that may not be apparent during normal use.
