A power distribution box has a holder with inner, deflectable lock arms for securing bus bars within the holder. When the bus bars are correctly and completely installed within the holder, engaging portions of the lock arms are received in apertures of the bus bars and the lock arms are in a locked position. A cover can fit over and properly seat on the holder. The cover has projections that slide behind the lock arms and retain the lock arms in the locked position, preventing further movement. The projections each include a blocking surface. If one or more of the bus bars are not correctly and completely installed in the holder, the related latch arms are in a deflected, unlocked position. The blocking surface of a corresponding projection abuts against the deflected lock arm and prevents proper and complete assembly of the cover onto the holder.
