Contrary to popular misconceptions, the human body usually has a relatively high impedance (compared with copper wire); if electricity is offered a path with very low resistancethe equipment grounding conductorit will take the low-resistance path back to the panel, trip the breaker, and cut off the power. Your copper grounding wire should also be in compliance with the relevant electrical code. The thicker the electrical wire, the lower the gauge - and the more current it can carry without resistance. Before equipment-grounding conductors (popularly called ground wires) were widespread, people could be electrocuted when they came in contact with voltage that, due to a fault like a loose wire, unintentionally energized the metal casing of a tool or an electrical appliance. Insulated wire is covered in a coating to keep it shielded from weather, heat and other outside factors. Ground wires bond all electrical devices and potentially current-carrying metal surfaces.
