New RV Electrical Wire, Wiring & Terminals

Shop new RV electrical wire, wiring, terminals and electrical connection supplies for travel trailers, fifth wheels, motorhomes, campers and other recreational vehicles. Whether you are repairing an existing circuit, adding electrical equipment or rewiring part of an RV, this collection brings together the wire and connection components commonly used throughout RV electrical systems.

Browse RV primary wire, duplex wire, wire terminals, electrical connectors and related wiring supplies for a wide range of recreational vehicle electrical projects. Available wire sizes, terminal styles and specifications vary by product, making it important to select electrical components according to the requirements of the circuit and equipment being installed.

RV Primary Wire & Electrical Wiring

Primary electrical wire is used throughout RV electrical systems for connecting equipment, accessories, lighting and other electrical components. Depending on the application, different wire gauges, conductor materials, insulation types and current capacities may be required.

When selecting replacement RV electrical wire, consider the required wire gauge, circuit amperage, voltage, wire length and environmental conditions. Using appropriately sized wire is important for electrical performance and safety, particularly on longer wiring runs where voltage drop can become a factor.

RV Duplex Wire & Multi-Conductor Wiring

Duplex wire combines multiple conductors within a single insulated cable, making it useful for many RV and recreational electrical installations. It can provide a cleaner wiring solution when both conductors need to travel between the same electrical components.

Available products may vary by conductor size, insulation, cable length and intended application. Always compare the wire specifications with the electrical requirements of the equipment and circuit before installation.

RV Wire Terminals & Electrical Connectors

Complete electrical repairs and installations with RV wire terminals and electrical connection components. Depending on current inventory, this collection may include ring terminals, butt connectors, spade terminals and other terminal styles used to create electrical connections throughout RV systems.

Electrical terminals should be properly matched to the wire gauge, conductor and connection point. Correct crimping and installation are important for creating reliable connections capable of handling vibration and movement encountered during RV travel.

12V RV Wiring & Electrical System Repairs

Many recreational vehicle accessories and systems operate from the RV's 12V DC electrical system, making wiring and electrical connections an important part of repairs, equipment installations and RV renovations. Lighting, pumps, fans, controls and numerous other components may rely on low-voltage wiring connected to the RV battery and charging system.

If your project also involves replacing the battery itself, browse our New Lithium & Deep Cycle Batteries collection for 12V and 6V battery options.

RV Converters, Inverters & Electrical Power Equipment

RV wiring often connects batteries and electrical circuits with larger power-management equipment. For replacement power equipment, browse our New RV Generators, Inverters & Converters collection.

If you specifically need a replacement converter or battery-charging converter, visit our New RV Converters collection for additional RV electrical power and charging equipment.

Southwire RV Electrical Products

Our electrical catalog includes products from established electrical and RV-industry manufacturers. If you are looking specifically for Southwire products, browse our existing Southwire RV Electrical & Surge Guard Products collection for additional RV electrical equipment and accessories.

Choosing the Correct RV Electrical Wire & Terminals

Electrical components should be selected according to the requirements of the individual circuit rather than appearance alone. Before ordering, verify the wire gauge, conductor specifications, terminal size, connection type, voltage and amperage requirements for your installation.

For repairs involving existing wiring, inspect nearby connectors and conductors for corrosion, heat damage, loose connections or deteriorated insulation. When modifying an RV electrical system, follow applicable manufacturer instructions and electrical requirements. If you are unsure about an electrical repair or installation, consider having the work completed or inspected by a qualified RV technician or electrician.
