Why is special fire fighting equipment needed for electrical and non electrical fires?
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it. Water if pure without contaminants does not conduct . Having stated that electrical fire can hardly be contained by water since the air itself will conduct electrons by ionization. So to contain an electrical fire a the oxygen must be removed and water will not do that.

How do you determine the equipment ground wire size for equipment?
It is an electrical code rule that is determined by the amount of current that a connected device draws. Depending on the amperage that the equipment will draw determines what the size of the wire needed to handle the fault current. The larger the amperage the larger the ground wire needed.
