Surge suppression involves installing devices on the incoming electrical, phone, and cable lines entering the building. These electrical devices divert surges that come into the building from a direct lightning strike or a strike to the surrounding property or electric wires. These devices minimize damage to the buildings' electronics by diverting surges that come from the power distribution company, or through the power lines.
Most surge suppression manufacturers claim that their surge suppression devices will eliminate at least 80% of any incoming surges. It is for this reason that we recommend multiple levels of protection. We recommend installing surge suppression devices on the lines entering the building, at electrical sub panels, and at the outlets with surge suppression power strips.
For a complete UL Master Label lightning protection system, surge suppression devices are required for all incoming service lines. These devices offer protection for the electrical system, the phone system, the cable line, and any other attached electronics. For optimal protection we recommend installing surge suppression devices on the main electrical panels, the sub panels, and at critical points of use.
