Distribution boxes must be surge protected
BS 7671:2018 tells us that SPD installations shall be protected against overcurrent, regulation 534. 5 details that this can be done with either an MCB or an in-built fuse. Surge protectors (Surge Protective Devices, SPD) installed in distribution board panels are primarily used to protect electrical equipment from transient voltages (surges or spikes) caused by lightning strikes, power grid fluctuations, or other factors. Additionally, an S e fire pump controller to provide the necessary protection. Surge protectors here act like a shield.
