New ceiling smart light.

[ItMightBeMe]

Hi guys,

I don't know anything about electrics and wouldn't want to hurt myself, but I need to replace the light on the ceiling. I cut the electricity to the upstairs and set about removing the old light. What I thought would be very simple turned out to be much more challenging than I thought. I currently have 3 cables - green/yellow, black and red. As far as I know the red is the live wire (from the switch). Black is neutral wire and green/yellow is ground. On the new light I only have inputs for live and neutral. What do I do with the green/yellow once I've connected live and neutral?

Insulate the earth wire (a bit of insulated terminal block* is easiest/safest) and carefully house it behind the light.

*Chop one of the ends off the old light terminal.

The three cables are likely power into lamp, power out of lamp to next one, and the switch. With the latter one black wire is switched line, and important you don't connect it to neutral.
There are special lighting junction boxes to terminate the wires into to make it a single cable to light.

You need one of these, in the UK except for a lamp suspended from a cable an earth wire must be run to the lamp even if not required and terminated.

I see no earth termial. So one will need to wire it as class II but you need a junction box to do this.

I don't know what you are smoking, but better not to do it any more before posting.
There is ONE cable with THREE conductrs.
RED, - switched live
BLACK - neutral
and EARTH

Nothing more.

It works! Thank you.
