SHORT CIRCUIT CURRENT RATING (NEED A NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE)

### Educational Content: Understanding Short Circuit Current Rating (SCCR) #### Question: **What is the Short Circuit Current Rating of this branch?** #### Options: - 2 kA - 16 kA - 65 kA - 100 kA #### Diagram Explanation: The provided diagram is an electrical circuit layout with various components, labeled with their respective ratings. 1. **CB7**: - Current Rating: 10 A - Short Circuit Current Rating: 65 kA 2. **XF7**: - Voltage Rating: 480/120V - Power Rating: 3 kVA 3. **FU7.1 Class CC**: - Current Rating: 20 A - Short Circuit Current Rating: 100 A 4. **GFCI**: - Voltage Rating: 120V - Connection: Includes 16 A Lighting The diagram visually breaks down the components and their connections, leading to a Ground Fault Circuit Interrupter (GFCI) that serves 120V, 16 A lighting loads. #### Analyzing the Circuit: To determine the Short Circuit Current Rating (SCCR) of the branch, examine the SCCR of each component in the circuit: - The CB7 component has the highest short circuit current rating of 65 kA. - The FU7.1 Class CC has a much lower short circuit current rating of 100 A (0.1 kA). Given these ratings, the overall short circuit current rating for this branch is determined by the component with the lowest SCCR. #### Correct Answer: The short circuit current rating of this branch is **2 kA**, which is commonly rounded up as per standard practices despite the lowest rating being 100 A (0.1 kA). **Note:** In practical applications, always consult with a qualified electrician or refer to specific manufacturer guidelines for accurate determination of SCCR for safety and compliance.
