*Question E4E13:
Where should a station AC surge protector be installed?*  

*Correct Answer is  C: On the single point ground panel*  

### AI Response: (may contain errors)  

To protect your amateur radio station from electrical surges, it's important to install an AC surge protector in the right location. Let's break down the options:

### Correct Answer: On the single point ground panel

1. **Why the correct answer is correct:**
   - The single point ground panel is the central location where all grounding and bonding connections are made. Installing the AC surge protector here ensures that any surge is diverted to ground before it can affect your equipment. This setup minimizes potential differences between different parts of your station, reducing the risk of damage.

### Why the other choices are incorrect:

2. **At the AC service panel:**
   - While surge protectors can be installed at the AC service panel to protect the entire building, this does not specifically protect the radio station equipment. The single point ground panel is more effective for station-specific protection.

3. **At an AC outlet:**
   - Installing a surge protector at an AC outlet only protects the devices plugged into that specific outlet. It does not provide comprehensive protection for the entire station setup, which is best achieved at the single point ground panel.

4. **On a ground rod outside the station:**
   - A ground rod is used for grounding purposes, but placing a surge protector directly on it is not practical or effective. The surge protector should be part of the single point ground system to ensure all equipment is equally protected.

### Useful Rule of Thumb:

- **Single Point Grounding:** This method ensures that all equipment is at the same electrical potential, reducing the risk of damage from surges. It is a best practice for protecting sensitive electronic equipment in a radio station.
