Thermal Classification of Electrical Insulating Materials
Thermal Classification of Electrical Insulating Materials, basis Permissible Temperature Rise above Ambient Temperatuer and Hotspot.

Busbar used in Switchboard Assemblies are Al or Cu, they have specific Weight basis size and Density of Atoms for given volume.
Arc Flash is light and heat produced as a result of Arc Fault, due to low impedance path, which causes electrical explosion or discharge.
Short-Circuit fault allows the current to flow through unintended path with very low impedance, which results into excessive current flow through the path.
Internal Arc Protection ensures Personal and ASSEMBLY protection under arcing conditions due to low impedance path, cause of electrical explosion.

Electric Shock is flow of external electric current through human body. RCD must be installed with 30mA sensitivity for protection against Electric Shock.
Current transformer Accuracy class is highest permissible percentage error at rated current for that accuracy class, as per IEC 61869-2 and IS 2705.
Heat is a flow of energy from higher temperature object to lower temperature object. Heat transfer continues until two objects reaches thermal equilibrium.
