Eliminating the risk, by knowing your responsibilities under AS/NZ 61439:2016

AS/NZS61439 - The ChangesStandards Australia/New Zealand introduced ASNZS61439 in May 2017 with a 5 year phasing in period.

Pre May 2021Either ASNZS3439, ASNZS61439 or IEC61439 may be specified for Switchboard design and construction in Australia and New Zealand

Principal Sponsor 13-15 November 2018Rotorua, NZ

Post May 2021ASNZS3439 can no longer be referenced. Only ASNZS61439 or IEC61439 may be specified for Switchboard design and construction in Australia and New Zealand

reference to TTA (type tested assembly) or PTTA (partial type tested assembly) disappears, assemblies now have 13 criteria that they need to be verified to, using 1 of the 3 following mythologies:

Ø type testingØ comparison with a type tested assemblyØ assessment (by calculation or application of design rules)

AS/NZS61439 - Why Change?

Ø removing ambiguity within the standard

Ø clear lines of accountability and

now that partial type testing has been removed from within with in ASNZS 61439 and replaced with full type testing What does that mean?
