Generator to RCBO Wiring: A Safety Guide

Connecting your AC generator to a Victron Quattro begins with the correct safety components. First, run a 6mm² 3-core cable (Live, Neutral, and Earth) from the generator to a dedicated RCBO. This device is essential because it provides dual protection against short circuits and earth leakage faults.

Why Correct Wiring Matters:

• Dual Protection: The RCBO shields your system from both overloads and dangerous leakage.
• Centralised Safety: Housing your generator and shore power RCBOs in one enclosure keeps your breakers organised.
• Easy Access: Mounting the enclosure near the engine hatch allows you to reset a tripped breaker instantly.
• Vibration Resistance: Using the provided ferrules prevents wire strands from splaying or loosening over time.
• Professional Finish: Ferrules ensure a robust, secure termination for long-term reliability.
• Seamless Power: Correct wiring allows the Quattro to accept and convert generator power without interruption.

Enclosure Placement and Shore Power

For the best results, position your RCBO enclosure within the engine room. However, you must ensure it is easily accessible when the hatch is open. Consequently, if a breaker trips while the generator is running, you can reset it immediately to minimise downtime. Furthermore, keeping all primary AC safety breakers in one location simplifies your maintenance routine.

Final Connection to the Quattro

From the dedicated RCBO, the 6mm² cable runs directly to the AC-in 1 terminals on the Victron Quattro. When making these final connections, you must always use the provided ferrules. Because a boat is a high-vibration environment, these ferrules are vital for safety. Ultimately, this professional approach ensures a secure connection and a more reliable power system for your vessel.
