Your shift briefing
You have just started the afternoon maintenance shift. A packaging line stopped mid-run: the conveyor motor will not start and the panel shows a tripped breaker. Production is losing money every minute it is down, but you will not rush - a wrong guess can damage the motor or hurt someone. Work the circuit step by step: identify the likely fault, calculate what the circuit should be doing, and dial in the correct resistance to get the motor current back on target.
