Southwire 30 Amp Portable Surge Guard with LCD Display 34930

Get top-tier electrical protection for your RV with the SouthWire Surge Guard 30A RV Surge Protector (Model 34930). This portable EMS-grade unit does far more than block voltage spikes — it continuously monitors your shore power and automatically responds to the voltage faults, wiring problems, and pedestal issues that quietly destroy RV gear, giving you genuine peace of mind every time you plug in.

More Than Surge Protection — Real Monitoring

The 34930 continuously monitors and displays voltage and amp draw (RMS) on its onboard LCD display, giving you real-time insight into exactly what your rig is pulling and what the pedestal is delivering. With 2,400 joules of multi-mode surge suppression, it delivers serious defense against voltage spikes.

Comprehensive Protection

The 34930 guards your RV against the full range of dangerous electrical conditions:

• Power surges
• Open ground
• Open neutral
• Elevated ground line current
• Low voltage (under 102V) and high voltage (over 136V)
• Overheating receptacle
• Reverse polarity
• Miswired pedestal

These are exactly the faults a basic surge strip can't catch — and exactly what damages air conditioners, converters, and sensitive electronics over time.

Smart, Equipment-Protecting Design

A 10-second countdown startup sequence and a 128-second reset delay protect your A/C compressor from the rapid cycling that can damage it. A commercial-grade brass receptacle delivers durable, high-quality connections, while automatic reset on power restoration brings your power back once conditions are safe.

Built for Easy, Secure Use

Convenient Easy-T-Pull™ handles make connecting and disconnecting the plug far easier, and an anti-theft lock ring on the cord secures the unit at the pedestal so it doesn't walk off while you're away.

Note: The 34930 features an onboard LCD display and does not work with a wireless monitor.
