Mersen Publishes NEC14 Reference Guide

"2014 National Electrical Code: Changes in Overcurrent and Surge Protection"

Mersen, formerly Ferraz Shawmut, recently published a reference guide titled "2014 National Electrical Code: Changes in Overcurrent and Surge Protection."


The NEC codifies the requirements for safe electrical installations into a single, standardized source. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA®), and while not itself a U.S. law, NEC use is commonly mandated by state or local law.

In this paper, Mersen identifies and explains selected key code changes in overcurrent and surge protection, including:

*New Circuit Breaker Requirements for 1200A Plus Circuits
*SPD Type 4 and New Requirements
*Surge Protection without Overcurrent Protection
*Short-Circuit Current Rating (SCCR)
*Solid State Motor Circuit Protection
*Ground Fault Protection (GFP) for 1000A Plus Circuits
*Sizing Transformer Protection
*PV Shut-off for First Responders
*Selective Coordination Requirements
*Selective Coordination Not Required in Hospitals

"This Reference Guide endeavors to inform electrical professionals seeking an understanding of the code updates and further demonstrates the analysis used in the final resolutions," says Peter Walsh, PE, Senior Field Engineer and author of the reference guide.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
