Electrostatic mesh in distribution box

ESD shipping boxes use conductive corrugated fiberboard to safely dissipate static charges and help prevent damage. A Faraday cage, named after the English scientist Michael Faraday, is an enclosure used to block electromagnetic fields. This is only true if the conductor is kept at a constant potential. Indeed, assuming electrostatic equilibrium and the concept of equipotential surface, one can argue by contradiction that there cannot be an electric field inside. From power and signal distribution to I&C applications and complete room.
