What is a surge?

Short-term spikes in voltage that

threaten downstream equipment and

cause immediate and long-term

damage.


Where do surges come from?

Internal (80%):

• Motors

• Contactors

• Transformers

• Load switching

• Office equipment

• Light dimmers

External (20%):

• Lightning

• Grid switching

• Electrical equipment

in adjacent buildings

• Utility capacitor

switching

• Line switching


Consequences

Surge events can wreak serious havoc on

inadequately protected facilities:

• Premature aging of equipment

• Process interruptions

• Catastrophic failures

Multiple surges can cause cumulative equipment

damage and eventually result in a catastrophic failure.

This is why robust surge

protection is critical and

required by building codes

for emergency systems.


The 2014 National Electrical

Code, Article 700.8 states:

“A listed [surge protective device]

shall be installed in or on all

emergency systems

switchboards and panelboards.”


This change requires surge

protection to be installed on all

emergency electrical equipment

to improve the reliability of

emergency power systems.


Let’s see what you know so far…

Are the majority of surges generated from

internal or external sources?

• Internal

• External


Are the majority of surges generated from internal or external sources?

Internal.

80% of surges are generated within a facility.

This is why executing a facility-wide cascaded

surge protection strategy is critical.

Appropriate surge protection should be applied

across a facility to create a layered defense

solution and ensure critical equipment is fully

protected.


How Eaton’s devices work

Most surges occur in nanoseconds. Mechanical

protective devices are not fast enough to protect

equipment from damaging surges.

Our surge protective devices shunt high energy surges

away from the equipment being protected through the

use of solid-state, thermally protected metal oxide

varistor (MOV) technology.

How important is installation to surge protection?

Proper installation is extremely important when

it comes to effective surge protection. Installation

directly impacts device performance.


Maximizing surge protection

Direct bus connected

Best protection, lowest

let-through voltage

Wired connection

through a breaker

Better than side

mount

Side mount

Good let-though voltage

if leads are short

Good Better Best

Twisting wires improves surge protective device

performance.

• True

• False


Twisting wires improves surge protective device performance

True: Twisting wires can reduce let-through voltage and

improve surge protective device performance.

If lead length is longer

than four inches,

applying one twist per

four inches of wire is

recommended to

improve surge

protection.
