Electrical Wiring – An Introduction
Electrical systems vary widely given their different uses. That being said, the basics of wiring something are not that hard to understand.
Wiring is the insulated conductor that carries electricity. The wire that is used in a building such as a home or a factory is called building wire. The wire inside a piece of machinery is usually called equipment wire. Wire is measured by its diameter. This measurement is known as the wire gauge. Wire gauge runs in reverse numerical order. In other words, the higher the gauge number, the smaller the wire diameter.
Electrical Power Tools Safety
Electricity typically travels in a carefully directed closed-system. Electrical shock can occur when the body becomes part of this system, or creates a new system path. The actual damage from shock is from current flow (amperes). As little as 50 milliamperes (or 1/20th of an ampere) can cause electrocution. The danger is multiplied by the amount of time (duration) that the shock is applied through the body. A lower voltage of say, a 120 volt household current can cause severe shock or death in as little as 3 or 4 seconds duration. Higher voltages at less duration can cause the same amount of current flow and damage
