Modular plug-in power distribution panel assembly for critical loads

A modular plug-in power distribution panel assembly for addition of critical loads, the modular plug-in power distribution panel assembly comprising:

• an electrical enclosure configured to accommodate a panel therewithin;
• a bus bar assembly comprising a plurality of bus bars operably coupled to the panel, wherein the bus bar assembly further comprises bus straps selectively configured and connected to a main bus to provide electrical insulation and enhance flexibility and operability of the modular plug-in power distribution panel assembly;
• a plurality of plug-in bases operably coupled to the panel via the bus bar assembly, wherein the plug-in bases are configured to connect a plurality of cables during initial installation for adding a configurable number of plug-in breakers to the panel without shutting power down;
• a plurality of plug-in breakers detachably coupled to the plug-in bases, wherein the plug-in breakers are configured to be coupled to the plug-in bases without powering down one of a main power and the critical loads;
• one or more barriers configured for the plug-in breakers, wherein the one or more barriers are configured to securely direct gases produced within the electrical enclosure, out of the electrical enclosure to an external environment, in an event of a short circuit;
• and
• a plurality of heat sinks operably coupled to terminals of the plug-in breakers, wherein the heat sinks are configured to cool the terminals of the plug-in breakers.
