The number of solar installations is growing fast and with it the
risk that mistakes assembling DC connectors lead to fires. Simple errors in installation that can cause an arc fault to develop include: poorly crimped joints, cross-mating connectors from different manufacturers, assembling electrodes while wet and incomplete insertion that doesn’t engage the connector locking mechanism.

Marley has launched the ArcBox™ enclosure, that simply snaps around a DC connector to ensure that if an arc ever occurs it is safely contained and doesn’t spread to combustible materials in or around the solar installation. The effectiveness of the product has been independently verified by the KIWA fire test laboratory and Loughborough University.

  • BIPV

  • Combustible roofs

  • High-consequence locations

BIPV solar installations are one application for the ArcBox since DC cabling is installed near combustible building materials. Flat roof solar installations above roof coverings such as single ply membrane or ashphalt is another. Some buildings, if put out of use even temporarily, would have high knock-on consequences – hospitals, schools, care homes, and factories are applications where risks must be carefully controlled.
