According to the provided information, what is the relationship between branch circuits and overcurrent protection?

The relationship between branch circuits and overcurrent protection emphasizes the importance of ensuring that the protection matches the load rating, particularly for continuous use. When a circuit operates continuously, it can generate heat and may lead to dangerous situations if not properly rated. Therefore, it's essential that overcurrent protection devices are rated appropriately for the load they are expected to handle.

This means that for branch circuits that are designed to support continuous loads, the overcurrent protection must be carefully selected to match or exceed the load rating specified. This ensures that the circuit can operate safely without tripping the protection device unnecessarily while also providing adequate safeguarding against overload conditions. Matching the protection with the load ensures both efficiency and safety in the electrical system.
