How to protect electrical appliances from voltage in a distribution box
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. There are several categories of SPDs, each designed for specific applications within the power. A simple and relatively inexpensive solution is to plug sensitive electronics into a quality surge protector. Ultimately, protection is not optional—it's a critical backbone of any electrical distribution network.
