A thick earthing wire, or a wide, flat conductor, is preferred, because it's more
important to minimize henrys (inductance) in the earthing system than to reduce
ohms (resistance). For the same reason, corners and small angles in an earthing
conductor should be avoided, and the conductor should approach any connections
from a parallel direction.
The earthing wire does not normally carry current.

no use laying an earthing strip in a cable tray better tap both the ends of the earthing wire to the trunking,it will save your wire also,or lay out a cable in the other trunking where you have low voltage wire running in.
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
Making a load On, By using a clamp meter for measuring the current in the wires : we find a reading in Amps. if we clamp the neutral wire. and zero when clamping the earthing wire.

earth wire not cnnected from main earth
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
Depends how thick the wire is.
Nutral wire can be measured by using clamp meter, if there is a current passing through the wire, we got a reading in the clamp meter i.e. 2A. If we clamp the earth wire by the clamp meter the reading will be zero.
Thin wire.
Electrical earthing is classified into many types as Neutral earthing Body earthing Pipe earthing Plate earthing Chemical earthing Ground Compound Earthing
