Electrical system faults
- Arc Fault Home Page - arcing faults are one cause of electrical fires
- Faulty Electrical Outlets - The Unnoticed Hazard - much has been written about power-line voltage spikes, surges, dips and conducted high frequency noise, very little has appeared in personal and small business computer magazines about another electrical problem--miswired and defective electrical wall outlets

- Ceeform picture - Ceeform are also know as MK Commando connectors to BS4343.Circular plastic connectors favoured in the temporary power distribution business.Colour coded for easy identification and safety. Most common in europe are red = 415V, blue =230V, yellow = 110V. Most Also available in grey and purple. US types have differnet colour coding (blue=208V). Connectors are available as three phase (4 or 5 poles) and single phase (3 poles). Standard sizes are as follows: 125A, 63A, 32A and 16A
- Ceeform 4 pahase connector picture - standardized three phase power connector used around world, standardized in CEE 17, standard sizes: 125A, 63A, 32A and 16A
- Ceeform single phase connector - standardized single phase power connector used around world, standardized in CEE 17, standard sizes: 125A, 63A, 32A and 16A
- IEC 309-1 and IEC 309-2 Pin & Sleeve Devices - IEC 309-2 configurations for plugs (or inlets) and receptacles (or connectors) are single-rated which assures proper mating of devices with the same voltage and amperage. It is virtually impossible to couple a plug and receptacle of different voltage and/or amperage ratings.The size of the device is determined by the amperage rating. The voltage, of single rated Pin & Sleeve devices of the IEC 309-2 type, is determined by the location of the oversized female ground contact relative to the key-way located at the bottom of the housing. IEC 309 plugs and sockets are widely used for industrial purposes. Also known as CEE 17.

Mains power distribution in audio/video studios
Wiring in computer environments
AC is one of those things we never think about-even most electronics textbooks consider it to be a simple, 60-Hertz 120-volt RMS sine wave or 50-Herz 230-volt RMS sine wave (depends on where you live). Many books mention any impurities only in passing. But it's not that simple. The mains power can contain radio frequency interference, fluctuations in the voltage, high voltage spikes and even short breaks in power distribution.
