Unboxing and Parts Identification
The Hughes POWER WATCHDOG surge protector, model PWD 50 (50-amp hardwired version), arrived well-packaged. The box contained all necessary components, including the surge protector unit, mounting brackets, screws, and wire connectors. A clear instruction manual was also included, simplifying the installation process.

The unit itself is compact and robust. Key components are easily identifiable: the ground terminal, hot lines (L1 and L2), and neutral. The set screws for wire connections are conveniently located beneath removable rubber covers for protection against accidental contact. The clear labeling made it easy to identify each component.

Safety Precautions and Preparation
Before beginning any electrical work, safety is paramount. Always disconnect your shore power and any batteries. Turn off your main breakers as an additional precaution. Use a non-contact voltage tester to verify that all wires are completely de-energized before proceeding. This prevents potential electrical shocks and ensures safe installation.

I meticulously followed these safety procedures. My non-contact voltage tester confirmed the absence of any voltage in the wires prior to starting the installation. This step is absolutely essential for a safe and successful installation.

Mounting and Wiring
Installation of the brackets was straightforward. I attached the top bracket, tightened the screws, and then repeated the process for the bottom bracket. This provided a secure and stable base for the surge protector.

My camper already had an automatic transfer switch, which I was not using. This simplified the wiring process because I could directly connect the surge protector to the existing wires without cutting. If you're working with a different setup, you might need to cut into the wires, carefully stripping and labeling the cables before connecting them to the surge protector.

Connecting the Wires and Final Installation
With the wires labeled (highly recommended!), I carefully connected the AC in and AC out wires to the appropriate terminals on the surge protector. The clear labels on the surge protector ensured that each wire was connected correctly. I tightened the set screws securely after connecting each wire.

Finally, I mounted the surge protector to the floor of the camper using the provided hardware and secured the cable retainer straps. A neat and professional installation resulted.

Conclusion and Review
The Hughes POWER WATCHDOG surge protector was relatively easy to install, thanks to the clear instructions and well-designed unit. The labeling of both the unit and wires was extremely helpful. The surge protector seems robust and provides peace of mind knowing my sensitive electronics are protected from power surges.
Overall, I highly recommend the Hughes POWER WATCHDOG surge protector for RVers and anyone needing reliable surge protection. It's a worthwhile investment to safeguard your electrical equipment from damage caused by power surges and offers great value for money and security.
