What is the size of earthing plate in CM?
plate is used it should not be of less than 60 cm x 60 cm x 6.35 mm. The earthing electrode should be situated at a place at least 11/2metre away from (i.e. outside) the building whose installation system is being earthed.
What is the size of copper earth plate Mcq?
Plate Earthing: Copper with dimensions 60 cm x 60 cm x 3.18 mm is used. Pipe Earthing: A galvanized steel pipe is usually 40 mm (1.5 in) in diameter and 2.75 m (9 ft) in length is used.

What is the specification of earthing plate?
Specification of GI earth plate is 60 cm * 60 cm * 6 mm.
What is the specification of copper plate electrode for earthing?
The copper plate shall be connected to copper earth strip of 25*3 mm at minimum two points and joints shall be protected by heavy coat of bitumen, The GI plate shall be connected to GI earth strip of 25*6 mm at minimum two points and joints shall be protected by heavy coat of bitumen.
What is the dimension of the copper strips used for the strip earthing Mcq?
25 mm × 4 mm.
What is earthing Mcq?
Earthing MCQ Question 2 Detailed Solution Earthing: It is to provide a sufficiently low impedance path and means to carry and dissipate electric currents into the ground under normal and fault conditions without exceeding any operating and equipment limits or adversely affecting continuity of service.
How do you calculate the size of the earth electrode?
Calculate GI strip having width of 12mm , length of 2200 meter buried in ground at depth of 200mm, soil resistivity is 72.44 Ω-meter.
- Resistance of earth strip(Re) = 72.44/2×3.14x2200x(loge (2x2200x2200/.2x.012)) = 0.050 Ω
- From above calculation overall resistance of 60 no of earthing pipes (Rp) = 0.133 Ω.
What is the best size for an Earth plate?
Finding the Size for Earth Plates & Earth Electrodes Since both earth plates are below from water level, therefore, 2ft x2ft x 1/8 plate size is most suitable for each main and secondary plate. Continuity should be well after testing the system but also consider the earth resistance as well.
What is the best plate size for a solar system?
Since both earth plates are below from water level, therefore, 2ft x2ft x 1/8 plate size is most suitable for each main and secondary plate. Continuity should be well after testing the system but also consider the earth resistance as well.
What size wire do you use for earthing leads?
Now we can find the proper size of earthing leads. Since the cable size of transformer on L.T side is 37/.083. So we can use 3/0 SWG copper wire (or 3/16 x ¾ or 1/8 in) Copper strip.
