Quizplus · Accepted Answer

Both technicians are correct. Technician A is correct in stating that a fuse blowing immediately upon installation typically indicates a short to ground, as this suggests an unintended direct path to ground is allowing excessive current to flow, causing the fuse to blow. Technician B is correct in stating that if the short to ground occurs on the ground side of the load component but before a grounding switch, the component will not turn off because the short provides a continuous path to ground, bypassing the control that the switch would normally provide.
