A surge protector is an electrical device that is used to protect equipment against power surges and voltage spikes while blocking voltage over a safe threshold (approximately 120 V). When a threshold is over 120V, a surge protector shorts to ground voltage or blocks the voltage

As most surge protectors are installed in parallel to the power panels, normally the best place to install the device is on the main service or panel feeding the facility.
