1. A water and electrical supply system for firefighting, comprising:
a water supply system configured to convey water from a water source to a hose for performing a firefighting task, the water supply system including:
a water inlet that receives the water from the water source in an upstream direction; and
a water outlet that releases the water from the water supply system in a downstream direction;
an electrical supply system configured to provide electrical power for performing a firefighting task, the electrical supply system including:
a set of conductors for electrically connecting the electrical supply system to an electrical power source;
wherein the water supply system comprises:
a fire hydrant that includes:
a barrel that extends upwardly from a ground surface, the barrel defining a barrel passage through which the water flows during use of the system;
a valve configured to move between a seated position and an unseated position to selectively prevent or permit the water flow through the barrel during corresponding non-use and in-use states of the system; and
at least one water outlet in fluid communication with the barrel passage to direct water out of the fire hydrant in a downstream direction toward a firefighting device;
wherein the set of electrical conductors defines a set of power source conductors and the electrical supply system comprises:
an electrical connector assembly that includes:
a connector housing that is sealed out of fluid communication with respect to the barrel passage; and
an electrical connector that is:
mounted within the connector housing; and
configured to selectively couple to an accessory power cord for providing electrical power to an electric firefighting accessory; and
wherein the connector housing is supported by the fire hydrant.
