ePanorama wiring documents
Cable ImpedanceThis document tries to clear out some details of transmission lines and cable inductance. This document is only a brief introduction to those topics. If you expect to work much with transmission lines, coaxial or otherwise, then it will be worth your while to get a book on that subject. The ideal book depends on your background in phsics or electrical engineering, and in mathematics.Coaxial cablesIntroduction to coaxial cables, connection information and cable data.Twisted pair wiringIntroduction and notes on twisted pair wiring as used in telecommunications, networking and and audio/video applications.Current loopsCurrent loops are a standard which are used widely in process automation. 20 mA are wirely used for transmitting serial communication data to programmable process controlling devices. Other widely used standard is 4-20mA current loop, which is used for transmitting analogue measurement signals between the sensor and measurement device.Ground Fault InterruptersA groundfault circuit interrupter (GFCI) is an electrical device which protects personnel by detecting potentially hazardous ground faults and quickly disconnecting power from the circuit. A potentially dangerous ground fault is any amount of current above the level that may deliver a dangerous shock.Color code of AC power cordsDesciption of color codes in AC power cords.
