Will PowerGuard products protect my equipment from a lightning strike?
While we have several testimonials related to complete protection from local area and apparent direct lightning strikes (where the protection was completely destroyed), we do not view this as conclusive proof of our ability to provide total protection from such events. The variables related to each incident, location, how the strike occurred, the path the strike took, can mean that the levels of energy actually dissipated by the protection is vast.

The energy of lightning is estimated to range in Giga Joules; it is unrealistic to expect that the energy dissipation rating of any Plug Product is likely to provide total protection against damage from direct or close by lightning strike.

In a properly wired installation, and with the right combination of Power Protection strategies PowerGuard Professional Series protection will significantly reduce the risk of damage to equipment from AC Mains power related incidents or induced surges from local area lightning strikes. Protected equipment may sustain damage from let through voltage, but the damage will be significantly less than unprotected equipment. (Note: Indemnity Warranty).
