🔍 Key Concepts

• Control circuit vs. power circuit in the three‑phase oven diagram • How the heater contactor coil is energized through the 1‑amp fuses • Which oven heating elements are connected to L1, L2, and L3 after the contactor closes

💭 Think About

• Trace the path of current that energizes the heater contactor coil. What happens to that path if one of the 1‑amp fuses is open? • If the contactor coil is not energized, what happens to the three main contacts feeding the oven heating elements? • Compare the oven element connections in figure A with the element arrangements in figure B. Which elements depend on the contactor being closed to receive power?

✅ Before You Answer

• Identify which parts of the circuit are upstream and downstream of the 1‑amp control fuses • Verify whether any heating elements are directly connected to the 10‑amp line fuses without going through the heater contactor • Confirm what the contactor’s state (open/closed) must be for elements #1 through #7 to energize
