A SDoC (Supplier Declaration of Conformity) is a way of manufacturers, importers and suppliers providing evidence that electrical equipment (Including cable, fittings and appliances) is safe for use and meets New Zealand standards.
SDoCs and MIs (manufacturers instructions) are not always required. If they are required Master Electricians recommends details of the SDoCs and MIs be included when issuing CoCs (Certificates of Compliance).
Supplier Declaration of Conformity
ilar but more stringent process and require WorkSafe approval see WorkSafe for more information.
Alternatively equipment registered on the EESS (Electrical Equipment Safety Scheme) WorkSafe online database is deemed to be approved, if the New Zealand manufacturer, importer or supplier is registered on the EESS as a responsible or affiliated supplier.
An SDOC for a declared medium risk article must contain a description of the article, and a statement that the article complies with:
- The appropriate standard listed in schedule 4 of ESR, or
- AS/NZS 3820 or the Conformity Cooperation Agreement.
If (1) or (2) applies, access to the test report or other supportive documents must be available from the person supplying the article.
Installations and fittings
The overall safety of the installation is still the responsibility of the person certifying the installation.
In Master Electricians opinion: when fittings are purchased from a reputable electrical wholesaler or supplier, in New Zealand, the wholesaler or supplier is responsible for ensuring the fittings meet ESR 80, 81 and 83.
If the purchaser is unsure if a fitting complies they should ask for a copy of the SDoC, including the test report. If no such copy is available the purchaser should not purchase the fitting.
Anyone who installs electrical fittings or appliances without an SDoC must take all responsibility for the installation.
Where an SDoC exists, it should be referenced on or attached to the CoC. For an example of an SDoC form see WorkSafe website.
Customer imported and supplied equipment
Customer imported electrical equipment, for the customers own use, does not require an SDoC. The installer will need to ensure it is electrically safe. Master Electricians have more information available on this matter in a separate article.
Manufacturer’s instructions
Manufacturers regularly provide instructions for safe and compliant installation of fittings and appliances. Manufacturers and importers and suppliers of appliances and fittings are responsible for ensuring that any instructions, if followed for installation, testing, maintenance or connecting, will result in a compliant and safe installation.
Electrical workers, as per ESR 14A, are entitled to rely on in good faith manufacturer’s instructions unless they clearly state that they do not apply in New Zealand.
If you rely on the instructions and the work is general or high risk PEW, MIs should be referenced on or attached to the CoC.
