🔍 Key Concepts

• Difference between a wiring diagram and a ladder (line) diagram/schematic in motor control circuits • How physical location of devices vs logical operation of the circuit is shown in different drawings • What a one-line diagram and a pictorial drawing typically look like compared to control schematics

💭 Think About

• Look at Figure A and ask: does it seem to show how the devices are laid out in the enclosure and how the wires actually run between them, or does it show just the logical path of current? • Look at Figure B and ask: are the components arranged as they physically appear, or are they lined up in rungs between power lines, emphasizing control logic? • Compare both figures to what you would expect from a true one-line diagram or a pictorial drawing—do either of these figures match those styles?

✅ Before You Answer

• Identify which figure shows actual wire connections and component placement inside a panel or on a door. • Identify which figure shows control circuit rungs between supply lines, with contacts and coils arranged for logic rather than physical location. • Eliminate any options that label either figure as a one-line or pictorial drawing if the figure clearly has more detail than those types usually show.
