Abstract: A utility distribution pedestal for marine and recreational vehicles can be entirely separated and removed from its base without disturbing the service connections. Pedestals with different selections of receptacles can be quickly exchanged to change the service provided by any given pedestal location. Individual receptacle panels in the pedestal offering different combinations of receptacles can easily be added or exchanged after initial installation as utility needs change or for maintenance without any screw terminal wire removal. A metering system using four current transformers is controlled by an integrated mechanical jumper for switching the system into single or two phase configurations for one or two user readouts or a three-phase configuration for a one user readout. No pedestal disassembly or assembly is required to change these configurations. Remote monitoring for wireless metering and electromechanical counters may also be employed.
