What type of protection is not intended to protect against overload?

Short circuit protection
Ground fault protection
Branch short-circuit protection
Surge protection

The correct answer is: Branch short-circuit protection

Branch short-circuit protection is designed specifically to safeguard electrical circuits from conditions that could lead to short circuits. Its primary function is to interrupt the flow of electricity when a fault occurs that causes an excessive current, thereby preventing damage to the wiring and associated components. Overload protection, on the other hand, is meant to protect circuits from drawing more current than they can handle over an extended period, which can lead to overheating and potential failure. The other options listed, such as short circuit protection, ground fault protection, and surge protection, serve functions that include aspects of overload protection or are related to protecting against specific electrical anomalies, but branch short-circuit protection distinctly targets the immediate risk of short circuits rather than long-term overload conditions.
