Surge Protection for Commercial Facilities – Part 2

As discussed in Part 1, sudden electrical changes in a circuit, power or voltage surges are short bursts of energy that can damage electrical or electronic equipment. Part 2 will discuss Businesses and Equipment at Risk, Protections, and Minimizing Disruptions.

Businesses and Equipment at Risk

Almost every enterprise must rely on modern electrical equipment in some way, which can be degraded or damaged by surges. Business continuity can be endangered without having proper protection. Companies that have electronic systems in more dangerous locations, dependent on substandard local utilities, or located in areas where lightning strikes are frequent, will be more vulnerable to the harmful effects of power surges.


Businesses large and small should acknowledge the risk of power surges and the advantages of surge protection. The specific requirements of each company should also be considered. Consulting with licensed electricians who are experienced and expert in installing surge protection solutions, will garner the best results. Below are several best practices for facilities.

  • Ensure systems share a common ground and have entry to the facility a few feet from one another.
  • Install surge protection at distribution panels as safeguards from surges generated by high-powered motors, welding equipment, etc.
  • Low voltage and communications lines should be installed away from power cables and at right angles.
  • Sensitive equipment and communications lines should have surge protection.
  • Surge protection should be installed to shield systems from external power sources.

Minimize Power Disruptions

Another best practice is minimizing power disruptions. Every facility’s electrical system requires proper grounding as set forth by the NEC (National Electrical Code). Every cable, satellite, and telephone wire must be connected to the identical grounding point. Structured cabling must be located at a proper distance away from power cables that can generate surges. Telecommunications areas require wiring that minimizes electromagnetic disturbances and electrical surges.

Part 3 will cover Surge Suppression Devices, Selection, and Uninterruptible Power Supply.
