How do I connect an ungrounded LED driver to a GST18i3 3-core installation?
Answer: GST18i3 3-core grounded connections comply with NEN-EN-IEC61535, the standard for pluggable electrical connections in fixed installations. But they also comply with the NEN-EN-IEC60320 standard for device connections. To connect a Class II ungrounded device to a pluggable electrical installation as per NEN 1010 with NEN-EN-IEC61535 products, a GST18 connector has been developed that fits the GST18i3 connectors in the fixed installation. However, this has no grounding conductor in the cable. This connector therefore only complies with NEN-EN-IEC60320 and not with NEN-EN-IEC61535, and may therefore only be used as a ‘device connector’. It is therefore only supplied as a male connecting cable with a maximum length of 200 cm, which can be attached to a Class II ungrounded or grounded device. No further connections may be made to the Class II device. In terms of its application, this can be compared to a normal appliance plug in the form of a protective earth plug that does not have protective earth contacts, Type C CEE 7-17, which is plugged into a grounded socket. These do not have a grounding conductor either. They comply with the NEN 1020 standard, which is partly based on the NEN-EN-IEC 60320.

- Which GST18 connector do you use to connect a cooker in a kitchen?
Answer: This depends on the type of cooker and the installation. Some cookers may be connected in several ways. Please refer to the instructions for use. The following options apply:
- 2-group cooker on a so-called Cooking Group (L1,N1,PE,L2,N2): GST18i35 green
- Three-phase cooker (L1,L2,L3,PE,N) on a three-phase system (L1,L2,L3,PE,N): GST18i5 black
- Two-phase cooker (L1,L2,PE,N) on a three-phase system (L1,L2,L3,PE,N): GSt18i4 black
- Single-phase cooker (L,PE,N) on a three-phase system (L1,L2,L3,PE,N): GST18i3 black
- Single-phase cooker (L,PE,N) on a single-phase system (L,PE,N): GST18i3 black
- Which Wieland pluggable electrical connections may be used in chloride-containing environments (swimming pools)?
Answer: Spring-clamp connectors in particular are susceptible to chloride stress corrosion, as they have stainless steel components. These products should not be used in chloride-containing environments such as swimming pools. However, other metals, including copper, can also be affected by chlorides at excessive concentrations. It is therefore always advisable to have installations in such environments inspected periodically. We recommend the use of screw and crimp connectors of the RST range. They do not contain any stainless steel components and, due to the high IP value, they are much less susceptible to degradation by chlorides through condensation.
Rationale:
- In chlorinated environments, chlorides are present in the air. This happens, for example, in chlorinated swimming pools. Stainless steel is sensitive to chloride corrosion. This action triggers chloride stress corrosion and fractures may occur in these metals.
- Spring-clamp connectors in electrical connections are also partly made of stainless steel and also appear to be susceptible to chloride stress corrosion. Spring-clamp connections are widely used in electrical engineering, e.g. in junction boxes, socket outlets, lighting connections, etc.
