Rwandan Outdoor Distribution Box Dimensions

Outdoor distribution boxes in Rwanda are typically fabricated from 2 mm GI sheet steel with illustrative dimensions subject to ±10% tolerance, designed for IP55 protection and outdoor use.Typical Construction and DimensionsOutdoor distribution boxes in Rwanda, as per technical specifications, are generally made from 2 mm galvanized iron (GI) sheet steel with reinforced channels for structural stability. The roof is slightly slanted with a 50 mm overhang at the front and back to prevent water ingress. The boxes include Godrej-type 3-position locking systems, concealed hinges, and two solid earthing points on either side for safety compliance .The dimensions provided in technical documents are illustrative, with a tolerance of ±10%, allowing manufacturers or bidders to specify their own dimensions based on project requirements. Boxes are designed to accommodate one bus bar arrangement with 4-pole MCCB and outgoing feeder arrangements with 2 sets of 3-pole MCCBs, ensuring adequate clearance and insulation .Design ConsiderationsIP Rating: IP55 for dust and water protection, suitable for outdoor exposure .Cable Entry: Heavy-duty, double compression cable glands for incoming and outgoing cables. Detachable plates are provided for fixing cable glands.Internal Layout: Provision for lighting, copper bus bars (25x4 mm), and insulation barriers between MCCBs to prevent heat transfer.Customization: Boxes can be tailored for voltage levels, number of feeders, and space constraints while maintaining compliance with REG standards .SummaryWhile exact dimensions are project-specific, a standard outdoor distribution box in Rwanda is robust, weatherproof, and designed for low-tension electrical distribution, with flexibility in size to meet installation and operational requirements. For precise dimensions, manufacturers or project engineers typically provide drawings based on the illustrative specifications with ±10% tolerance outlined in REG and technical guidelines .
