What the unit is and who it suits

BG SyncEV White EV Consumer Unit 100A Main Switch 40A DP RCBO SPD CFEV5RDAW-01 is a dedicated EV circuit protection unit intended for charger supplies rather than wider property distribution. It is built for installations that want one enclosure containing the main switch, final-circuit RCBO protection and Type 2 surge protection already configured for EV charger work.

The unit suits single-phase EV charger circuits up to 40A where the installer prefers a double-pole Type A RCBO arrangement on the charger way rather than a separate RCD and MCB layout. It is especially relevant for exterior charger positions where a weather-resistant board is required and where the client also wants a cleaner visual match on lighter wall finishes.

Protection layout and product logic

BG lists CFEV5RDAW-01 as populated with one 100A double-pole main switch, one 40A 30mA Type A double-pole RCBO and one Type 2 SPD. That gives the installer a compact protection arrangement in which the RCBO handles final-circuit overcurrent and residual-current protection, while the 100A main switch provides incoming isolation for the board.

That configuration is attractive on charger work because it keeps the charger circuit protection self-contained and reduces the need to select separate devices. The Type A RCBO also reflects the needs of EV circuits, where pulsating DC residual currents are part of the protection picture rather than an edge case.

Enclosure design and environmental suitability

BG states that the enclosure is made from UV-stable 2mm cast aluminium ADC12 and carries IP65 protection. Published dimensions are 176 x 233 x 100mm. The enclosure includes built-in padlock provision, wire-seal tabs and multiple M20 knockouts that can be drilled to M32. It also includes a removable cover blank.

Those features matter on real installs because charger protection boards are often mounted where they face weather, wash-down splash, dust and direct sunlight. The white RAL9016 finish is the clear visual difference on this model and can make it easier to integrate with white render, painted masonry or cleaner commercial exteriors.

Installation fit and intended use

CFEV5RDAW-01 is best used on a dedicated EV radial where the installer wants 100A board isolation, combined 40A double-pole Type A RCBO protection and built-in Type 2 surge protection. It is a purpose-led charger board rather than a mini consumer unit being repurposed for EV work. That helps keep the protective logic consistent and the installation process more repeatable.

Because it arrives pre-configured, the board can also reduce selection time on site and help standardise similar jobs across a trade team.

Warranty and product confidence

BG’s current EV circuit protection literature shows a 10-year warranty for this IP65 enclosure family. That is valuable for a safety-critical fixed component expected to stay in place around the charger installation for the long term.

Why this exact variant may be the right choice

CFEV5RDAW-01 is the right choice where the site wants the RCBO-based BG SyncEV board in a white finish rather than grey. It is especially suitable where the board will remain visible on a lighter wall and the owner wants the protection equipment to look cleaner as part of the finished charger installation.
