The main reason - is risck of electrocution. Water conducts electricity pretty easily. If the person extinguishing the fire isn't insulated, they could die from electric shock.
The most suitable extinguisher for electrical fires is dry-powder.
because we will get shock
The carbon dioxide fire extinguisher can be used on electrical fires, where there is a danger of an electrical shock if a soda water extinguisher was used.
Yes and No! Electrical fires are not really fires, the electrical sparks cause the ignition of the combustibles around it. Thos fires can have a blanket used in their extinguishment. The power source needs to be removed to stop the sparking.
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.
red = water and is used for wood paper textiles and solid material fires. DO not use on liquid elictrical or metal fires. blue = powder and is used for liquid and electrical fires. DO not use on metal fires. yellow = foam and is used for liquid fires. DO not use on electrical or metal fires black = carbon dioxide (CO) and is used for liquid and electrical fires DO not use on metal fires. halon can be used on all fires as well as dry chemical
Class E fire is a type of fire classification used in Australia, referring to fires involving electrical equipment. These fires occur when electricity ignites flammable materials such as wires, appliances, or electrical systems. It is important to use appropriate fire extinguishing methods and avoid using water on these fires as it can further escalate the situation.
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.

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.
A 'dry powder' extinguisher. Water or foam extinguishers will destroy the circuits (and shouldn't be used on electrical fires).
An electrical fire is a class "C" fire. A Class "C" fire is actually a class "A" or "B" fire that is caused by electrical current.
Circuit breaker or a fuse
liquid and electrical fires.
