New safety standard for DC isolating switches in solar photovoltaic (PV) installations


A new standard aimed at improving safety outcomes for isolators used in renewable energy installations has been developed.

From 30 June 2018, DC isolating switches used in solar PV and renewable energy installations must comply with a Level 3 certification under the Electrical Equipment Safety System (EESS), Workplace  Health and Safety Queensland said.

“This means DC isolating switches must have a valid Certificate of Conformity confirming the product complies with Australian Standard AS 60947.3:2018. The brand and all relevant models must be registered to the responsible supplier in the EESS national database and be marked with the Regulatory Compliance Mark (RCM).”

Suppliers have until 30 June 2019 to sell existing stock up, according to the EESS.

Wholesalers, retailers and electrical contractors in Queensland may continue to supply or install the DC isolators they have in stock, provided the importer or manufacturer of the isolators is registered with the EESS and the isolator bears the RCM.
