An extruded rail-mount, for mounting devices to a variety of rails, with a support leg that provides upward support against the forceful pressure exerted when wires are screwed onto screw terminals at the edges of the mounted device. The mount is substantially constant longitudinally. The rail-mount has a thin, plank-like substrate with latitudinally upward arms and downward kinked legs and a downward support leg. The arms have catches to grab onto / support circuit boards or other devices. Kinked legs have catches to grab onto / mount a chosen rail. When the rail-mount is mounted on a rail, the support leg is of a length to support against the surface to which the rail is secured. Because rails are relatively narrow, the mount's utility is such that attachment to a rail provides support to one side of a mounted device and the support leg provides support for the opposite side of the device.

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.
