I live in Eu and I connected the blue - neutral and the brown - hot to the light jack. There is no third ground wire in the cable and i am afraid to touch the black steel frame - is it dangerous, should I ground it or is it not necessary?

Please help

Edit and update:

I added new photos

I connected the blue neutral wire to the T210 and the brown wire to the OE50(or something like that) There is no label except class 1 insulation symbol on the light bulb socket and again class 1 on the electric cable and some others which I don't know what they mean.

No double insulation symbol so I guess I need to ground or buy a cable with ground wiring.

Here are the photos.

Update 2 and new related question.

I found out some celing lamp was wired as seen in photo. It is same level 1 insulation and the ground is not connected to nothing. Was that done wrong? Should I turn off electricity at the fuse box as precatution and connect green/yellow - ground wire to that steel bolt, would that ground it?

    A good clear photo of the approvals label would help... does it have the double insulation symbol? Mar 6, 2020 at 18:42
  • Do you have RCDs fitted?

    This is an electricity question (not electronics) and should be in "Home improvement".

  • How are you planning to ground it if there is no mains earth in your room? The pipes? In your case neutral is connected to the earth at the utility I suppose.

    @ty_1917 fact of neutral being connected to safety ground at the utility does not help you here. If anything it creates a false confidence that neutral is non-deadly. If that were true, they wouldn't put insulation on it :) Mar 6, 2020 at 20:07

It's class 1.

With Class 1 appliances, the user is protected by a combination of basic insulation and the provision of an earth connection, thus providing two levels of protection. When PAT Testing Class 1 appliances, Earth Continuity and Insulation Resistance tests are carried out. (source)

It needs a ground connection on the metalwork. There should be a grounding screw there somewhere.


From what I can see the lamp holder is isolated from ground. This may be why it did not have a ground. I believe this to be true because the connections go through the ceramic and the screw that holds the assembly is offset. A ground is a good thing if you have it available but if your rules are like ours a lamp holder with non conductive parts is not required to have a ground.
