One universe is mistaken for one fixture per slot

A fictional lighting designer allocates one DMX address to each of sixty fixtures and assumes the design fits because sixty is below five hundred twelve. Each chosen fixture personality actually uses sixteen consecutive data slots. A different sheet lists balanced linear loads, but the real equipment includes nonlinear supplies. A crew member proposes increasing a protective-device setting after nuisance trips without investigating the cause. This written exercise connects no power and operates no fixture. Separate console channels, fixture footprints and universe capacity; then identify why the electrical assumptions and proposed protection change need actual competent review rather than being settled by the addressing calculation.
