Southwire Surge Guard protectors differ in more than their 30-amp and 50-amp plugs. Some portable versions provide surge suppression and pedestal wiring indicators, while other portable and hardwired models monitor incoming voltage and can automatically disconnect power during specified faults. This model-specific guide compares those roles and identifies the correct companion remote displays.
Three types of shore-power protection
These original identification diagrams describe the purpose of the equipment. They are not wiring plans and do not replace the RV's circuit breakers or safe power-source requirements.

Southwire 44260 is the 30-amp portable protector with 2,100 joules of listed surge suppression. The 50-amp 44270 provides 4,200 joules. Joules describe surge-energy handling; they do not identify an RV's allowable continuous electrical load or the protection against sustained high or low voltage.
The advanced 34931 and 34951 portable models, and permanent 35530 and 35550 units, offer broader incoming-power monitoring. An RV using a 30A TT-30 shore inlet does not become a 50A RV by using an adapter. Match the installed inlet, cord and distribution system.
Identify the correct remote display before ordering
Southwire 40301 is the remote display listed for the 34931 and 34951 portable Surge Guard protectors. The separate 40300-10 remote LCD is listed for 35530 and 35550 hardwired protectors and includes a 50-foot communication cable. These are model-specific accessories; do not choose a display simply because it carries the Surge Guard brand.
A display cannot provide surge protection or replace the main protection unit. Check the exact parent device and the existing communications connection. Hardwired system work must follow the manufacturer's instructions and be done by qualified personnel.

Manufacturer model information
Southwire's Surge Guard product documentation identifies the portable 44260/44270 and 34931/34951 protectors as separate model families, along with 35530/35550 hardwired units. Review the official instructions for the exact model when assessing fault protection, acceptable shore-power supply and compatible accessories.
