Fire Extinguisher

A fire extinguisher is a critical, hand-held active safety device filled with extinguishing agents (dry chemical, CO2, water, or wet chemical) designed to control small, contained fires, typically in emergencies.

Air Circuit Breaker

Air Circuit Breaker (ACB) is an electrical safety device that automatically opens a circuit during a fault, such as an overload or short circuit, to protect equipment. It uses air as an arc-quenching medium to extinguish the electric arc that forms when the circuit is broken. #

THHN-2 vs THWN-2

THHN-2 is a type of building wire used primarily for electrical wiring in residential, commercial, and industrial applications. The acronym stands for Thermoplastic High Heat-resistant Nylon-coated, with the "-2" indicating that the wire is rated for 90°C (194°F) in both dry and wet locations.

THWN-2 is a type of electrical wire that stands for Thermoplastic Heat- and Water-resistant Nylon-coated, with the "-2" indicating that it is rated for 90°C (194°F) in both wet and dry locations. It is commonly used for general-purpose wiring in buildings, especially for circuits requiring water-resistant insulation. #
