If the Assembly Manufacturer deviates from the Original Manufacturer’s explicit instructions (e.g., substituting a different brand of circuit breaker or changing busbar geometry without approval), they become the de facto Original Manufacturer. This means they inherit full responsibility for performing expensive laboratory design verifications themselves. The 13 Design Verification Checks
