DP 1
For systems above 120 VDC, if a load break disconnection device has not been installed adjacent to the array then has a disconnection point been provided to isolate each string at the PV modules? Applicable rating: Needs Rectification | AS/NZS 5033:2021 Clause 4.3.3.1 |
DP 2
If installed, do all disconnection points conform to the following requirements? Are adjacent to the PV modules of the PV array. – Are readily available. – Are protected against weather and water, and no more than 150mm from the edge of the PV modules that they are installed under. – Are adequately supported. But able to be disconnected – Have both positive and negative disconnection device located together. Applicable rating: Needs Rectification | AS/NZS 5033:2021 Clause 4.3.3.1 |
DP 4

DP 9
Is any PV d.c wiring located in a ceiling space between a disconnection point and a load break disconnection device, installed within 0.6m above the surface and between 1 to 1.5m from the internal surface of an external wall, and not attached to the roof structure? Applicable rating: Needs Rectification | AS/NZS 5033:2021 clause 4.4.5.2.3 (b) and figure 4.6 |
DP 5
If PV d.c. wiring is located in a ceiling space between a disconnection point and a load break disconnection device using the vertical drop method laid out in figure 4.5 of AS/NZS 5033:2021, is the conduit vertical drop located within 200mm of the vertical edge of the load break disconnector? Applicable rating: Needs Rectification | AS/NZS 5033:2021 clause 4.5.5.2.3 (c) and figure 4.5 |
DP 6
If PV d.c. wiring systems have been installed between the disconnection point and a load break disconnection device and located in an accessible ceiling space or within and accessible floor, Has a warning label stating the below been installed adjacent to the access hatch? WARNING: HAZARDOUS d.c. VOLTAGE Solar d.c. cables in conduit have been installed in this ceiling space. The conduit is labelled "SOLAR" and care must be taken while working nearby. The internal solar d.c. cables may be live and must not be disturbed or damaged. Applicable rating: Improvements Identified (For Information) | AS/NZS 5033:2021 clause 5.3.1.2 |
DP 7
Do all PV string disconnection points have a sign with the following information, printed on both the positive and negative cables, within 100mm of the disconnection point?
