A 100%-rated, touch-safe, 800-ampere (A)/1000 A/1200 A, wall-mounted or floor-mounted, modular plug-in power distribution panel assembly (MPIPDPA) is provided for addition of critical loads. The MPIPDPA includes a bus bar assembly with bus bars operably coupled to a panel accommodated in an electrical enclosure, and bus straps selectively configured for providing electrical insulation and ensuring operability of the MPIPDPA. Multiple plug-in bases are operably coupled to the bus bar assembly. Configurable 100%-rated, 150 A/250 A/400 A/600 A plug-in breakers are detachably coupled to the plug-in bases without having to power down a main power or the critical loads. One or more barriers are provided for the plug-in breakers to securely direct gases produced within the electrical enclosure, out of the electrical enclosure to an external environment. Multiple heat sinks are operably coupled to terminals of the plug-in breakers for cooling the terminals of the plug-in breakers to ensure safety and standards compliance.
