XVB 4G4 vs XVB 5G4: What's the difference?
Understanding the difference between these two cables is essential to choosing the right model:
| Caractéristique | XVB 4G4 (ce produit) | XVB 5G4 |
|---|---|---|
| Nombre de conducteurs | 4 conducteurs | 5 conducteurs |
| Configuration | 3 phases + terre (SANS neutre) | 3 phases + neutre + terre (AVEC neutre) |

| Diamètre | Plus compact (~11-12 mm) | Plus large (~12-13 mm) |
| Prix | Plus économique | Légèrement plus cher |
| Recommandation | Installation triphasée pure équilibrée | Installation mixte ou besoin de neutre |
How to choose?
- Choose the XVB 4G4 if your inverter or equipment operates in balanced three-phase without the need for a neutral (pure photovoltaic injection, three-phase motors 4-6 kW).
- Choose XVB 5G4 if you have single-phase loads in addition to three-phase loads, or if your inverter requires a neutral conductor.
Advantages of the XVB 4G4 cable for photovoltaic installations
Material and financial savings: By eliminating the neutral conductor not required for balanced three-phase installations, the XVB 4G4 cable offers a significant cost reduction compared with the XVB 5G4. This saving also has an impact on protection (four-pole circuit breakers instead of five-pole).
Optimised cross-section for medium power: With its 4 mm² cross-section, the XVB 4G4 cable offers an excellent compromise between carrying capacity (up to 34A when laid underground) and ease of handling. It is perfectly sized for three-phase photovoltaic inverters from 4 to 6 kW, a segment that is very common in Belgian residential installations.
Optimised installation: With one less conductor and an intermediate cross-section (4 mm²), the XVB 4G4 cable is more compact and lighter than higher cross-sections. Its smaller diameter makes it easier to fit in Ø20-25mm ducts and reduces the space required in cable trays.
Simplified electrical configuration: For 4 to 6 kW three-phase photovoltaic inverters operating in pure injection mode (without single-phase local consumption), the absence of a neutral simplifies wiring and avoids problems of imbalance between phases and neutral.
💡 Expert advice: always check the specifications of your inverter before choosing between XVB 4G4 and XVB 5G4. Some inverters necessarily require a neutral conductor for correct operation, even in three-phase. Consult the technical documentation for your UPS or contact our technical support.
Sizing and choice of cross-section
The choice of XVB cable cross-section depends on the power of the installation, the length of the cable and the installation method. For a 4G4 mm² XVB cable:
- Maximum recommended power: 4 to 6 kW three-phase (depending on length)
- Length up to 15 m: Three-phase inverters up to 6 kW
- Length 15-25 m: Three-phase inverters up to 5 kW
- Over 25 m: Choose a larger cross-section (6 mm² minimum)

Installation and use
The XVB 4G4 mm² cable must be carefully laid in accordance with good practice and the requirements of the RGIE :
Preparation and planning :
- Compatibility check: BEFORE any purchase, confirm that your inverter or equipment operates in three-phase mode WITHOUT a neutral conductor.
- Calculating lengths: Measure the path precisely, allowing a 10-15% margin for connections.
- Choice of installation method: Decide whether the installation will be surface-mounted, flush-mounted or underground
- Selecting protection: Use a four-pole circuit breaker (4 poles: 3 phases + earth) of 25A or 32A depending on the power rating.
Installation techniques:
- Exposed installation: Fix the cable every 30-40 cm with suitable clamps. Avoid excessively tight bends (minimum radius 70 mm).
- Flush-mounted installation: Make sufficiently deep recesses and pull the cable without excessive stress.
- Duct laying: Use Ø20-25mm ICTA ducts. Pull the cable with a wire puller, taking care not to force it.
- Buried installation: Place the cable in a sheath at least 60 cm underground. Mark the passage with red warning netting 20 cm below the surface.
Connections and splicing :
- Stripping: Use a cable stripper to remove the outer sheath, then strip 10-12 mm off each conductor.
- Phase identification: Follow the colour code (Black=L1, Brown=L2, Grey=L3, Green-Yellow=Earth). There is NO blue conductor (no neutral).
- Tightening: Use terminals suitable for the 4 mm² cross-section. Tighten firmly but not excessively.
- Checking: Check the continuity of each phase and earth, and that there are no short circuits before switching on the power.
