Abstract
A utility pedestal primarily designed as a marina power pedestal but useful in connection with recreational vehicles and other power consuming units. Twin half shell housing members joined by an anodized aluminum strip closure member forms an upper pedestal. The strip closure member has an inner extending flange to which a central divider is secured to divide the upper pedestal into two substantially symmetrical compartments, one for high voltage and one for low voltage such as telephones and cable television. An open bottom base pedestal supports the upper pedestal and is secured to the dock pier. It contains the water utilities and is provided with a slotted top to introduce high voltage cables into the high voltage compartment of the upper pedestal. Because each utility pedestal services two units, the compartmentalized upper pedestal is provided with conduits for transferring low voltage cables through the high voltage compartment and for isolating high voltage cables from low voltage components in the low voltage compartment.
