Advantages of copper wire in making safer and effective cables

There are five basic types of Fire Alarm Cable:
FPL - Power Limited General Purpose
FPLR - Power Limited Suitable from Floor to Floor
FPLP - Power Limited Suitable for use in Ducts, Plenums, and other spaces
NPLF - Non-Power Limited General Purpose
NPLFP - Non-Power Limited ......

In the United States, smaller conductors are measured using the American Wire Gauge (AWG). With the gauge system, the higher the number is, the smaller the cable will be. For larger wires, circular mils are used. MCM sizes, also called kcmils (kilo-circular mils), are for even larger cables. One MCM......

UL stands for “Underwriter‘s Laboratory” and is an independent US testing organisation, similar to the German VDE. Based on the the National Electrical Code (NEC, also referred to as NFPA 79) – the safety standard prevalent in the USA for electrical installations – the Underwriter’s Laboratory defin......

Verband der Elektrotechnik, Elektronik und Informationstechnik – more commonly known as VDE – is the Association for Electrical, Electronic and Information Technologies and their related sciences, technologies and applications.

Under no circumstances should cable and wire act as fuses enabling a fire to spread. They must not act as fuel for a fire, and should not release any dangerous substances. That is exactly what happens with materials whose flame retardation is based on halogens – i.e. fluorine, chlorine, bromine or i......
