According to the principle of graded lightning protection, and based on the likelihood of a building being struck. Distribution boxes prevent those situations at a much larger scale. Key requirements include temperature rise tests 2, IP rating verification 3, short-circuit withstand testing 4, detailed technical files, and compliance with.
