The Applications and Limitations of UL 1449 for Surge Protective Devices (SPDs)

Posted by The nVent ERICO Team on Mar 5, 2019 8:00:00 AM

In the U.S—with the exception of utility, telecommunications and rail industries—all AC power connected surge protective devices (SPDs) must be installed in accordance with National Electrical Code (NEC). 

The 2017 revision of the NEC includes three articles that address SPD application and expand its use outside for emergency power systems:

  • Article 620.51(E), Surge Protection for Elevators, Dumbwaiters, Escalators, Moving Walks, Platform Lifts and Stairway Chairlifts
  • Article 645.18, Surge Protection for Critical Operations Data Systems
  • Article 670.6, Surge Protection for Industrial Machinery

The NEC requires that a SPD be “listed” or recognized for such purpose and approved by a Nationally Recognized Testing Laboratory (NRTL). One example of a NRTL listing service is Underwriters Laboratories Inc. (UL).

The broadening application of the NEC furthers the responsibility for NRTLs, like UL, to prioritize safety for facilities, electrical professionals and patrons. Read on to learn about the main UL standard that assesses SPD products for safety and provides basic ratings for determining applications.

The 2 Most Important Factors to Weigh When Selecting Ground Rod Material

Posted by The nVent ERICO Team on Oct 30, 2018 8:02:00 AM

The purpose of a grounding system is to protect people, structures and equipment, and to ensure maximum safety from electrical system faults and lightning. A vital piece of the system is the ground electrode. The overall system’s reliability is dependent on this component.

When using a ground rod for the ground electrode, the general performance or conductivity of available materials is minimal, but the service life of each material can vary by decades.

The Difference Between Lightning Protection and Surge Protection

Posted by The nVent ERICO Team on Oct 16, 2018 8:02:00 AM

Lightning is known to be the most significant source of surges—bolts have been recorded to have a million to a billion volts and between 10,000 to 200,000 amps. However, lightning only makes up a portion of all transient events in a facility.

Because transients can originate from both external sources (like lightning) and internal sources, facilities ought to have both a lightning protection system and surge protection installed.

This begs the question: what is the difference between these two systems, and how do they work together?

The Pros and Cons of 4 Common Ground Rod Materials

Posted by The nVent ERICO Team on Sep 18, 2018 8:02:00 AM

When it comes to selecting a ground rod, engineers must avoid a one-size-fits-all approach. Different factors—material, soil resistivity, location, facility type, size, among others—play into the overall efficiency and service life of both the ground rod and overall grounding system.

Below we provide key considerations for ground material selection and then compare the most common types.
