From 1 July new rules stipulate that PV electrical equipment must have an anti-condensation function (AS/NZS3000:2018 Wiring Rules clause 1.7.2).
Where a condensation issue could arise within electrical equipment, a breathing / pressure equalization valve shall be installed.
As a result, PROJOY has developed new technology and upgraded their range to comply.
A breathing valve has been incorporated on the side of enclosures to ensure the free flow of air, and to prevent water, dust, oil and fog from entering the switch, dramatically reducing condensation.
