Water and foam extinguishants are highly conductive and will cause catastrophic short circuits, electrical shock, or equipment destruction when applied to live electrical switchboards. COSWP and marine fire-fighting doctrines strictly mandate non-conductive agents such as CO2 or dry powder for electrical fires.
