Installing Surge Protection Devices (SPDs) can help prevent the electrical equipment damage associated with lightning activity. SPDs operate by diverting surge energy to ground before the energy can pass to sensitive equipment. SPDs must have a reliable, low impedance path to ground in order to function effectively.
Proper electrical system grounding and bonding is essential for operation of sensitive equipment and is also necessary to allow surge protective devices to function properly. The National
Electrical Code (NEC) article 250 contains the requirements for proper grounding and bonding.
All SPDs require a good connection to ground (the earth). A minimum of one Ground rod should be installed at all buildings with electric power. Depending on soil conditions, it may be necessary to install a second ground rod to supplement the first ground rod. Concrete footer grounds (using rebar or buried copper wires) can serve as one ground rod.
All utilities that enter a facility should be electrically connected (bonded) together. This includes:
– Metal gas piping
– Metal water piping
– Telephone service
– Cable TV service
– Satellite TV service
– TV antenna service
NEC articles 800, 810, and 820 list the requirements for grounding and lightning protection on telecommunications services. Any telecommunications service must have a primary lightning protector or grounding block installed where the service enters the house. The protectors and grounding blocks should be connected to the electrical ground.
If communication equipment such as TV Antennas, Satellite Dishes, or Telephone services enter the house more than 25 feet away from the electric service, the communication equipment must have its own nearby ground rod and a #6 AWG copper conductor to connect the telecommunication ground rod to the electrical ground.
TVA recommends a multi-level approach to applying electrical system SPDs:
1) Main Service Entrance- at meter base, main panel, or closest main panel to service entrance.
2) Distribution sub-Panel (if present)- at all sub-panels that supply sensitive equipment such as electronics, computers, televisions, or air conditioning equipment.
3) Point-of-use- Surge protected multi-outlet strips where sensitive equipment (such as a computer) connects to wall outlet.

Applying surge protection in this fashion provides three barriers between the electrical system and the end-use equipment. These barriers offer three distinct points to stop a surge before it can damage sensitive equipment.
Be sure to follow all manufacturers’ instructions regarding the installation of permanently mounted SPDs. Improper installation techniques can degrade or negate the performance of
SPDs. The units should be installed so that the wires between the SPD and the circuit breaker connections are kept as short and straight as possible. Do not install the SPD wires with sharp bends or kinks.
Specifications to look for when purchasing SPDs for electrical systems:
• UL 1449 (3rd Edition) listing- this is the latest UL safety standard for SPDs
• For Line Voltage Models, the SPD should provide multi-mode protection against Line to Line, Line to Neutral, and Line to Ground transients
• Line Voltage Models should also have indicator lights that display the operational status of the SPD. These lights should be checked on a regular basis and especially after a thunderstorm.
• Point-of-use surge protectors (plug strips) should be chosen which provide connections for all utilities that connect to a particular device. Example: A point-of-use protector for a television should also have provisions to connect the cable TV service. A point-ofuse protector for a computer should also have provisions to connect the telephone/DSL/internet line.
The installation of all SPDs should comply with NEC article 285. All permanently mounted
SPDs should be connected to a circuit breaker. Reference the manufacturer’s specific instructions for circuit breaker ratings.
­
It is often convenient to provide uninterruptible power for computers so that work in progress is not lost when the power unexpectedly goes out. Some newer flat screen televisions also require a cool-down time after they are turned off. When the power goes out, the TVs are not able to cool down as needed and damage can result. TVA recommends that you consider installing uninterruptible power supplies (UPS) for equipment such as computers and televisions
(especially if cool down time is necessary). UPSs typically incorporate built-in SPDs and are available with telephone and cable surge protection connections.

– Brochure for Eaton Electrical Corporation’s brand of permanently mounted electrical system surge suppressors for 120/240 volt applications at main panels.
– A brochure for a Citel coax (cable TV) surge protector.
– Brochures for some plug-strip type SPDs for use at sensitive electronic equipment.
– Brochure for Tripp-Lite Uninterruptible Power Supply
TVA does not endorse one manufacturer over another, the information is only provided as an example of equipment that meets the recommended specifications. Many vendors make equipment meeting these recommendations, TVA recommends obtaining multiple quotes for surge protection equipment.
