Weight of metals basis specific density

Metals used in Switchboard Assemblies are CRCA, Al, Cu, etc have specific Weight basis its Density of Atoms for given volume.

The formula for weight calculation is:

Weight = (L / 1000) x (W / 1000) x ( t ) x ( ρ )

  • Weight in Kg
  • L = length in mm
  • W = width in mm
  • t = thickness in mm
  • ρ = Specific material density in kg/m3

What is Specific Density of material?

The Ratio between mass and volume of material determines the Specific Density, its units are kg/m3 or gm/cm3

What is Specific gravity?

It is the ratio between the density of an object and a reference substance, it does not have units.

    Arc Flash Hazard Risk Category

    HRC – Hazard Risk Category is determined by amount of Incident Energy released upto defined boundary from the source of Arc Flash Point.

    How to do Powder Coating ?

    In Powder coating process, CRCA surface is given Anti Corrosive Surface treatment, then Epoxy Powder is applied, melted and hardened.

    What is Arc Flash ?

    Arc Flash is light and heat produced as a result of Arc Fault, due to low impedance path, which causes electrical explosion or discharge.
