I realise this has been covered before, but couldn't find an answer to my problem.
I have a metal light fitting with a 12v transformer inside powering 9 bulbs on arms. The transformer has a Double insulation symbol but the light has an earth wire. Looking at it, it appears that this is only connected to the casing, as just 2 wires into transformer, but the only cable running through this is 12v. Do I need to earth?
