Claim:
A master electrical insulation barrier panel, comprising a plurality of optionally removable knock-out features, wherein each of said knock-out features has a shape defined by a peripheral edge to provide a plurality of knock-out features each having a different shape, wherein said peripheral edge comprises a plurality of snapable tabs, and wherein each snapable tab is separated by an opening configured to create a breakable weak link in a non-electrically conductive brittle material used for fabricating said master electrical insulation barrier wherein a weak link is associated with each of said optionally removable knock-out features, and wherein each of said optionally removable knock-out features corresponds to an optional opening for at least one possible electrical connection, such that at least one knock-out feature can be optionally removed from said master electrical insulation barrier panel during installation of said master electrical insulation barrier panel to create said optional opening for at least one of said electrical connection, and whereby said master electrical insulation barrier panel can be used in multiple scenarios and applications.
