Ideally, every electrical panel should
be surge protected. However, this
may not be practical or feasible.
Proven surge protection practices
do not have to be complicated or
costly. All you need to do is
address the following:
1- Where should hard wired
SPDs be installed on the
electrical system?
2- What size and type SPD
should be used?
Surge Protecting a Sports Complex
Service Entrance
Applying surge protection at the incoming electrical service “Stops Surges Before They Get In.” These types of surges contain the largest surge energy warranting 300 kA or more of surge current redundancy.

Outside Loads
SPDs should be installed at distribution panels feeding remote parking garage, parking lot lights, stadium lights, etc. to prevent back feeding surges entering the main building.

Lower Voltage Panels
If the campus is supplied with a higher system voltage (i.e. a 277/480V service), 120V panels need SPDs to condition residual surges leaving the service entrance SPD as well as any internally generated surges. Examples could be panels powering security equipment, broadcast control centers, concessions stands, or any other panels powering sensitive electronic-rich locations.

Individual Equipment
Even if surge protection is applied at the previous locations, redundant protection maybe warranted for sensitive, costly equipment. This may include stadium LED signs, chillers, and drives.

Data Lines
Security, fire alarm, and telephone systems using copper communications lines need protection especially for communication circuits running to and from stadium signage. Also, control circuits for escalators, elevators, and other drive-controlled equipment.
