Description
Southwire Surge Guard 44380 is a portable 120-volt, 30 amp RV surge protector with enhanced campground power diagnostics. It provides 2,100 joules of surge protection and is UL/CUL listed for RV owners who want a listed portable protector with a fully enclosed receptacle cover.
This model is designed for travel trailers, pop-ups, motorhomes, and other RVs equipped with a standard three-prong, 30-amp shore-power connection. Its easy-to-read LED fault chart helps identify campground wiring and power conditions before you rely on the pedestal connection.
Southwire Surge Guard 44380 Enhanced Diagnostics
The Southwire Surge Guard 44380 analyzes campground pedestal power and indicates several conditions that may affect an RV connection:
- Open neutral
- Open ground
- Reverse polarity
- Open circuit or no power
- Surge-protection status
- Overheating at the plug or receptacle
The LED fault chart provides a clear visual reference, helping you identify the detected condition without having to interpret a complicated digital display.

Is the Southwire Surge Guard 44380 Right for Your RV?
The Southwire Surge Guard 44380 is intended for RVs using a standard 30-amp shore-power connection. A typical 30-amp RV plug has three prongs and uses 120-volt electrical service.
This model may be the right choice when:
- Your RV uses 30-amp shore power
- You want a portable protector rather than a hardwired installation
- You want enhanced diagnostics beyond basic pedestal testing
- You want surge-protection status indication
- You want plug and receptacle overheating indication
- You specifically want a UL/CUL-listed model
- You want a fully enclosed receptacle cover
- You frequently connect to unfamiliar campground power pedestals
Who Should Consider a Different Surge Protector?
The Southwire Surge Guard 44380 is not intended for an RV using a 50-amp, four-prong shore-power connection. A 50-amp RV requires a properly matched 50-amp protector, such as the Southwire Surge Guard 44390.
This model is also not a full-protection electrical management system. The manufacturer brochure does not list automatic high- or low-voltage shutdown, delayed power restoration, amperage display, continuous RMS voltage monitoring, or wireless monitoring as features of the 44380.
Customers who require automatic voltage protection and power disconnection should compare Southwire’s full-protection portable or hardwired models rather than relying on the 44380 for functions it does not provide.
Southwire 44380 Compared with the 44280
The Southwire Surge Guard 44280 and the 44380 are both portable 120-volt, 30-amp models with 2,100 joules of surge protection and the same enhanced diagnostic conditions.
The principal difference is that the manufacturer identifies the 44380 as UL/CUL listed and equipped with a fully enclosed receptacle cover. Choose the 44280 when those added features are not required. Choose the 44380 when you specifically want the listed model and enclosed receptacle design.
Southwire 44380 Compared with the 44390
The Southwire Surge Guard 44380 is the 30-amp model, while the Southwire Surge Guard 44390 is designed for 120/240-volt, 50-amp RV electrical service.
The 44390 provides 4,200 joules of surge protection and can indicate missing voltage on either 50-amp power leg. The 44380 provides 2,100 joules and is designed for the simpler single-leg electrical system used by 30-amp RVs.
Choose based on the shore-power connection installed on your RV. Do not select a 50-amp protector for a 30-amp RV or a 30-amp protector for a 50-amp RV.
Southwire Surge Guard 44380 Size and Security
The Southwire Surge Guard 44380 measures approximately 4.25 inches wide, 15 inches long, and 4.25 inches deep.
An anti-theft lock ring is built into the cord, allowing the owner to add an appropriate locking method when the protector is connected at a campground pedestal.
