🔍 Key Concepts

• Trace how L1, L2, and L3 feed the indicator lights and each heating element in figure A. • Distinguish between the line (10A) fuses and the control (1A) fuse, and what each one actually powers. • Notice which elements (1–7) are connected between which pairs of lines, and which pair feeds the power available light.

💭 Think About

• If the power available light is out, which pair of lines must have lost power? Look at exactly where that lamp is connected. • Only elements 6 and 7 are heating. From the wiring diagram, between which two lines are elements 6 and 7 connected? Which line is not required for them to heat? • Would blowing the 1A control fuse prevent the power available lamp from lighting, or only stop the contactor and oven‑on lamp?

✅ Before You Answer

• Verify on the diagram which lines feed the power available indicator and the oven on indicator. • Verify which heating elements are fed from L1–L2 and which (if any) are fed from a different line pair involving L3. • For each answer choice, mentally "remove" that fuse and check: Do both indicator lights go out and do only 6 and 7 still have a complete circuit?
