Which color indicates a circuit is not properly placed?

The color red is commonly associated with indications of danger, caution, or alertness in electrical systems. When a circuit is not properly placed, red serves as a visual warning to those working on or monitoring the system. This is crucial for maintaining safety in electrical work, as improper connections or placements can lead to short circuits or other hazardous situations. Red signals that immediate attention is required to address the issue before proceeding, ensuring that workers take the necessary precautions. Each color in electrical wiring typically has its own standard meanings, and in many contexts, red is explicitly used to denote something that needs to be corrected or is out of compliance.
