π Key Concepts
β’ Look at how each branch circuit in Group Control Center No. 1, Panel 404 is numbered (1P404, 2P404, 3P404, 4P404).
β’ Notice which vertical feeder is the third circuit from the left and follow it all the way down to the associated load.
β’ Match the circuit identification (e.g., 3P404, TXIA-26) to the equipment name printed directly below the motor symbol.
π Think About
β’ Which branch circuit label in the diagram clearly contains the number 3, and where does that conductor terminate at the bottom of the illustration?
β’ How are the other circuits (1, 2, and 4) connected, and which specific pieces of equipment do they feed? Use that pattern to confirm the one for circuit #3.
β’ Does the horsepower or kW rating shown beside each load help you doubleβcheck that you are tracing the correct circuit from the group control center?
β
Before You Answer
β’ Verify exactly which vertical feeder is tagged with 3P404 and TXIA-26 before deciding.
β’ Confirm that the equipment name you choose is printed directly below the load circle fed by that third circuit line.
β’ Make sure you are not confusing the protective device ratings at the top (AT/AF values) with the actual circuit numbers (1P404, 2P404, 3P404, 4P404).
