The Power Quality Pyramid

Wiring, Bonding, Grounding, Surge Protection and TVSS All Tiers of availability relies on this as a foundation Wiring, Bonding & Grounding Ensures full compliance with standards Avoids fault and safety issues of multiple grounds Enables optimal efficiency of Surge & TVSS protection Surge & TVSS NOTE: UPS is not a surge protection device If it does stop a surge it will most likely self destruct UPS is part of critical infra fabric and requires protection Cascaded Deployment most effective Category C rated (highest level) TVSS should be installed at the electrical service entrance to the building. All modes should be protected (Lines, neutral, ground). Category B TVSS can be installed at any critical distribution sub panels. This assumes a category C TVSS is at the main switchboard Category A plug-in TVSS/filters can be installed at critical wall receptacles This assumes a category C TVSS is at the main switchboard     Integrated for System level Efficiency, All Critical Fabric Protected
