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 Hospitality Facility
Service Entrance
Applying surge protection at the incoming electrical service “Stops Surges Before They Get In.”

Outside Loads
SPDs should be installed at remote workshops or guest houses, or at panels that supply external loads to prevent back feeding surges entering the main building.

Lower Voltage Panels
If the facility 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 labs, operating rooms, 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 elevators, hotel room load centers, kitchen equipment, chillers, etc.

Data Lines
Security, fire alarm, and telephone systems using copper communications lines need protection especially for communication circuits and elevator control circuits.
