Electrical grounding best practices
A good grounding system should provide the maximum safety from contact, electrical system faults and lightening. For a grounding system to perform efficiently over long periods of time, it should be designed and installed properly using reliable materials and proven techniques.
Grounding is important for three main reasons;
• Safety to people
• Protection of equipment and building which may come into contact with the live wires or systems.
• Electrical noise reduction
The electrical ground provides a current return path to the earth mass. The earth is usually considered to be an electrically neutral body with equal number of positive and negative charges which are distributed *** throughout the earth and any given time.**** RD
The effectiveness of the grounding system depends on the individual components. Some of the factors to consider include
• The grounding conductors : that connects noncurrent carrying metal parts to raceways, enclosures, etc
• Grounding electrodes
• Grounding Connectors
• Type of the soil and environment Components of a building grounding system
The building grounding system consists of
• The exterior grounds
• The electrical service ground
• Building interior grounding
• Equipment grounding and bonding
• Lightening protection
