How to modify the distribution box during lightning protection testing

How to modify the distribution box during lightning protection testing

During lightning protection testing, the distribution box should be temporarily isolated, equipped with surge protective devices, and all connections verified to ensure safe testing and compliance with standards.Key Steps for Modification1. Install or Verify Surge Protective Devices (SPDs) The distribution box should have a first-level surge protector installed on the main incoming line. This acts as the primary lightning protection for the building's electrical system, meeting standards such as GB50057-2010 for lightning protection design and T1 test requirements . Ensure the SPD is rated for the expected surge current and voltage. 2. Isolate Sensitive Circuits Before testing, disconnect or isolate sensitive equipment downstream of the distribution box to prevent damage from high-voltage surges. Temporary disconnection ensures that the energy from simulated or real lightning strikes does not reach vulnerable devices . 3. Verify Earthing and Equipotential Bonding All metallic parts of the distribution box and connected systems must be properly bonded to the earthing system. Low electrical resistance (typically
