2014 NEC® Code Changes Analyzed in Thomas & Betts’ Free Reference Guide Current Edition Includes T&B, ABB LP and ABB Power Products Items

Thomas & Betts (T&B) has published Analysis of NEC® Code Changes 2014, a free reference guide to changes in the 2014 National Electrical Code® (NEC®) that pertain to T&B’s products. This edition also covers code changes affecting ABB Low-Voltage Products (LP) and ABB Power Products. The 152-page guide is available as a print publication or it may be downloaded as an electronic PDF file.

The analysis guides readers in selecting the appropriate T&B products to comply with 2014 changes to the NEC®. T&B’s Analysis of the NEC® Code Changes 2014 is one of the most extensive code change books available from an electrical products manufacturer. Its scope has been significantly expanded as the result of ABB’s acquisition of T&B in 2012. The book is organized by NEC® article numbers with a table of contents, and includes illustrations of products and applications that pertain to code changes.

“This is the sixth edition of the T&B Code Changes book and includes, for the first time, changes affecting products offered by ABB Low Voltage and ABB Power Products,” said David Kendall, director, industry affairs, for Thomas & Betts. “Among these products are Baldor motors; low-, medium- and high-voltage switchgear; transformers; controls; smart meters; circuit breakers: electrical vehicle charging stations; and energy monitoring systems used in building automation.”

Why Capacitance? Benefits & Applications of Digital Capacitive Solutions

In this paper, readers will discover digital capacitive displacement measurement solutions not possible with conventional analog systems. The following applications address a wide range of industry sectors. Each example demonstrates how digital capacitive sensing systems rival the performance of more expensive and complex measurement systems at a fraction of the cost
