Do not forget this one
NFPA 20, 2010, A.9.3.2 A reliable power source possesses the following characteristics:
(3) The normal source of power is not supplied by overhead conductors outside the protected facility. Fire departments
responding to an incident at the protected facility will not operate aerial apparatus near live overhead power lines,
without exception. A backup source of power is required in case this scenario occurs and the normal source of powermust be shut off. Additionally, many utility providers will remove power to the protected facility by physically cutting the overhead conductors. If the normal source of power is provided by overhead conductors, which will not be identified,the utility provider could mistakenly cut the overhead conductor supplying the fire pump.
