What is a common misconception about electrical panel circuits?

The assertion that all circuits require the same amount of power is a common misconception because, in reality, different circuits are designed to handle varying loads based on their intended purposes. For example, a lighting circuit may carry much less power than a dedicated circuit intended for appliances like refrigerators or electric stoves, which require significantly more power due to their operational demands. Understanding the load requirements for different types of circuits is crucial for ensuring safety and efficiency in residential electrical installations. This highlights the importance of proper circuit design and load calculations during inspections to ensure that each circuit is appropriately rated for the devices it will serve.
