Thomas & Betts

Thomas & Betts (NYSE: TNB) is a designer and manufacturer of connectors and components for electrical and communication markets. Thomas and Betts was founded in 1898 by two young engineers from Princeton University, Robert M. Thomas and Hobart D. Betts. They formed an agency for selling conduit to electrical distributors during a time when incandescent electric lighting was first introduced to New York City. Thomas & Betts is notable as the inventor of cable ties in 1958 to facilitate assembling wire harnesses in airplanes. It has recently expanded its product offerings through the acquisition of leading brands in the power protection industry specifically focused on critical infrastructure.

ABB acquired Thomas & Betts for $3.9 billion, or $72 a share, in 2012 to become a major player in the North American low-voltage products market.

Nortek purchased the Thomas & Betts HVAC business unit (Reznor) from ABB in March 2014 for $260 million.

Memphis, Tennessee

Memphis is a city in the southwestern corner of the U.S. state of Tennessee and the county seat of Shelby County. The city is located on the fourth Chickasaw Bluff, south of the confluence of the Wolf and Mississippi rivers.

Memphis had a population of 653,450 in 2013, making it the largest city in the state of Tennessee, the largest city on the Mississippi River, the third largest in the greater Southeastern United States, and the 23rd largest in the United States.

The greater Memphis metropolitan area, including adjacent counties in Mississippi and Arkansas, had a 2014 population of 1,317,314. This makes Memphis the second-largest metropolitan area in Tennessee, surpassed by metropolitan Nashville.

Memphis is the youngest of Tennessee's major cities, founded in 1819 as a planned city by a group of wealthy Americans including judge John Overton and future president Andrew Jackson. A resident of Memphis is referred to as a Memphian, and the Memphis region is known, particularly to media outlets, as "Memphis & the Mid-South".

Low voltage

Low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, and in the electronics industry. Electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages. These definitions vary by country and specific code.

Definitions

In electrical power systems low voltage most commonly refers to mains voltage as used by lighting and portable appliances. "Low voltage" in this context still presents a risk of electric shock, but only a minor risk of electric arcs through the air.

The International Electrotechnical Commission (IEC) defines supply system low voltage as voltage in the range 50–1000 V AC or 120–1500 V DC.

In electrical power distribution, the United States 2005 National Electrical Code (NEC) defines low (distribution system) voltage as 0 - 49 volts. Low distribution system voltage is covered by 250.20(A) of this code.
