We all know how important earthing is to any machine or equipment. With the help of earthing strips, we should be able to bear and disperse the overcurrent very quickly.
Earthing is mainly divided into 6 parts which are as follows:
- Strip And Wire Earthing.
- Rod Earthing.
- Pipe Earthing.
- Plate Earthing.
- Coil Earthing.
- Chemical Earthing.
Plate Earthing and pipe earthing should be of good quality material. Which has good electrical properties. It is very important to provide airing in any place like a home, office, or factory which also protects the man with the machine from electric shock. That is why copper and galvanized steel are widely used metals.

Most Commonly Asked Questions:
What are copper strips used for?
Copper strips and DPC / DCC strips are used in electrical industries, motor generators, transformers, and household electrical appliances due to their high conductivity which cannot replace other non-ferrous materials like copper due to good mechanics.
How do I choose to earth strip size?
Required Earthing Conductor size = Cross-sectional area x Total allowance x Safety factor. Required Earthing Conductor size = 1125 Sq.mm say 1200 Sq.mm. Hence, Considered 1 Nox 12 x 100 mm GI Strip or 2 Nox 6 x 100 mm GI Strips.
What is an earthing strip?
GI earthing strip is used to provide earthing in spaces such as industrial, residential and commercial, etc.
How is earthing size calculated?
Allowable Current Density = 7.57×1000/(√100X1)=757 A/m2. The surface area of both sides of a single 600×600 mm Plate= 2 x lxw=2 x 0.06×0.06 = 0.72 m2. Max. current dissipated by one Earthing Plate = Current Density x Surface area of the electrode.
