Pneumatic tools’ or air tools are tools driven by gas, usually compressed air supplied by a gas compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO2) stored in small cylinders allowing for portability. Pneumatic tools are commonly cheaper and safer to run and maintain than their electric power tool counterparts, as well as having a higher power to weight ratio, allowing a smaller, lighter tool to accomplish the same task. Air tools were formerly unpopular in the DIY market, but are becoming increasingly popular, and have always been ubiquitous in industrial and manufacturing settings. Flow represents the quantity of compressed air that passes through a section over a unit of time. It is represented in l/min, m3, at the equivalent value in free air in conditions of standard reference atmosphere (SRA), i.e. +20 c, 65% of relative humidity, 1013 mbar, in accordance with norms NFE
Electrical wiring in general refers to insulated conductors used to carry electricity, and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that should apply worldwide 
Installing electrical wiring by cutting into the bricks of the building 
Terminal blocks for joining aluminum and copper conductors. The terminal blocks may be mounted on a DIN rail. 
An electrical "3G" power cable found commonly in modern European houses. The cable consists of 3 wires (2 wires + 1 grounding in case if cable has "3G" name) and is double-insulated.
