Abstract

Claims (46)

1 . An electrical installation component comprising:

a housing; and

a grounding element located within the housing for electrically grounding an electrical installation component, wherein the grounding element has a steel sheet component that is provided with a coating, wherein the coating is an alloy, and

wherein the electrical installation component is intended to be used in explosive atmospheres, and

wherein the electrical installation component is a junction box, terminal box, light, or switching distribution system, and

wherein the alloy comprises:

zinc as the base,

3 to 4 wt. % of aluminum,

2 to 4 wt. % of magnesium.

2 . The electrical installation component according to claim 1 , wherein the housing is designed as an outer insulating housing and the grounding element is arranged at inside walls of the housing, wherein the grounding element is electrically connected to a ground connection of the electrical installation component arranged outside the housing.

3 . The electrical installation component according to claim 2 , wherein the connection between the grounding element located inside the insulating housing and the ground connection located on the outside is designed such that the ingress protection level of the insulating housing is maintained.

9 . The electrical installation component according to claim 1 , wherein the alloy is applied by means of an electroplating method.

10 . The electrical installation component according to claim 1 , wherein the coating has a layer thickness of 2 to 25 μm.

11 . The electrical installation component according to claim 1 , wherein the coating has a layer thickness of 5 to 10 μm.

12 . The electrical installation component according to claim 1 , wherein the grounding element has a contact resistance of less than 6 mohms.

13 . The electrical installation component of claim 1 ,

wherein the housing is electrically insulating.

14 . The electrical installation component of claim 13 ,

wherein the electrically insulating housing is designed as a synthetic material housing or plastic housing.

15 . An electrical installation component comprising:

a housing; and

a grounding element located within the housing for electrically grounding an electrical installation component, wherein the grounding element has a steel sheet component that is provided with a coating, wherein the coating is an alloy,

wherein the alloy comprises the following:

zinc as the base,

3 to 4 wt. % of aluminum, and

2 to 4 wt. % of magnesium,

wherein the electrical installation component is a junction box, terminal box, light, or switching distribution system.

16 . The electrical installation component of claim 15 ,

wherein the housing is electrically insulating.

17 . The electrical installation component of claim 16 ,

wherein the electrically insulating housing is designed as a synthetic material housing or plastic housing.

18 . An electrical installation component comprising:

an electrically insulating housing; and

a grounding element located within the electrically insulating housing for electrically grounding an electrical installation component, wherein the grounding element has a steel sheet component that is provided with a coating, wherein the coating is an alloy, wherein the alloy comprises the following:

zinc as the base,

3 to 4 wt. % of aluminum,

2 to 4 wt. % of magnesium;

wherein the electrically insulating housing is designed as an outer electrically insulating housing and the grounding element is arranged at inside walls of the electrically insulating housing, wherein the grounding element is electrically connected to a ground connection of the electrical installation component arranged outside the electrically insulating housing,

wherein the connection between the grounding element located inside the electrically insulating housing and the ground connection located on the outside is designed such that the ingress protection level of the electrically insulating housing is maintained.

19 . The electrical installation component of claim 18 ,
