NEMA ANSI C136.2-2015

New Surge Protection for LED Roadway and Area Lighting

Overview of NEMA ANSI C136.2-2015

The latest release of ANSI C136.2-2015 provides surge

protection requirements for luminaires and control

devices. Based on performance requirements and

transient immunity testing, these devices can be classified

into three categories:

Threat to LED Lighting

LED luminaires are expected to use less electricity and

have a longer life span. However, Lightning and switching

surges can threaten or destroy these LED drivers.

These Threats can include:

Disruption

Surges can enter power and data lines directly or through

inductive coupling which can result in down time and corrupt

data or processing.

Degradation

Repeated stress can cause component degradation and

shorten the lifespan of equipment. This may not result in any

visual damage, though performance and ROI are at risk.

Destruction

Immediate failure to a device due to a high level of energy

from a surge. This can include burnt PCB’s and melting of

electronic components.

The “Box Concept”The Solution for LED Luminaires

To maintain the expected ROI, end users should select

luminaires that are designed, and fully tested to

comply with ANSI C136.2-2015.

This table shows the recommended C136.2-2015

transient immunity levels for common outdoor lighting

applications:

Lighting Application Electrical Transient Immunity Level Typical (6kV/3kA) Enhanced (10kV/5kA) Extreme (20kV/10kA)

Building entrance, building exterior XParking garage, parking lot, tunnel XStreet, roadway, stadium, airport X

Selecting the appropriate SPD

Surge Protective Devices (SPDs) should be UL 1449 Type 4CA Recognized or better and tested

to specific levels of ANSI C136.2-2015. UL Type 4CA devices have gone through more safety

testing than those that are only UL 1449 Type 5 Components. The C136.2-2015 level should be

selected based on the location of the Lighting application shown in the chart above.

In addition, the luminaire should be tested to ANSI C136.2-2015 with the SPD installed.

Coordination of the SPD is key in making sure that the luminaire and control devices pass C136.2-2015 and not only the SPD by itself passes. CITEL can help with this coordination and

testing!

Applicable Standards

NEMA ANSI C136.2-2015

American National Standard for Roadway and Area Lighting Equipment –

Dielectric Withstand and Electrical Transient Immunity Requirements.

NEC 2017, Article 285 Surge-Protective Devices (SPDs)

“This article covers general requirements, installation requirements, and

connection requirements for surge protective devices (SPDs) permanently

installed on premises wiring systems of 1000 volts or less.”

IEEE 1100 EE Std 1100-2005 8.6.1

“The selection of SPDs typically depends on the location of the device. The

SPDs are recommended to be sized per IEEE C62.41™ and IEEE C62.45

requirements to achieve proper coordination. SPDs should be

listed to UL 1449 4th edition.”

“With surge lab facilities in three countries, CITEL SPD’s are designed and are fully

tested to meet and exceed required industry standards.”
