Electrical safety

metal rod or metallic object to protect from lightning

reference point in an electrical circuit from which voltages are measured

physiological reaction or injury caused by electric current

bulk movement of electrical energy from a generating site to an electrical substation

electrical safety device used in household wiring

electrical energy at voltages high enough to inflict harm on living organisms

sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown

an era of clash between use of Alternating and Direct Current for electric power distribution

physical equipment that provides a low-impedance connection between a circuit or electrical installation and earth ground

low amounts of electrical volts

electrical safety classification of voltages lower than mains voltage which present a low shock risk

transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source

EU directives on work spaces with an explosive atmosphere

electrical safety protection technique

intentionally electrically connecting all exposed metallic items not designed to carry electricity in a room or building as protection from electric shock

electrical equipment in places where fire or explosion hazards may exist

electrical wiring standard
