hi, do downlight need to connect Earth as usually they only have Live & Neutral and unlike surface mounted they have plastic casing.

so for surface mounted can i just use an earth crimp connector (looks like a washer) and put it in between the light support mount & the screw onto the ceiling?

what about normal pendant lights? same thing connect earth to metal part of the body?

and do contractors normally pull Earth wire when doing looping for downlights or just pull Live & Neutral?

ok, so for downlight no need because their casing are made of plastic, just need to remember to turn off switch & DB when changing it as the clips are still metal?

ok so for Recess Downlight Round one do we need to ground it?

3 Lives going into switch no neutral or ground how does it work actually?

hi, is it true if you buy those programmable switch like Honeywell, to use it as light switch we need to pull the neutral line from the light wires to the switch? the light switch itself won't have the Neutral wire? it's a schneider light switch i plan to replace.

hi, i looked at your picture again, i figure the rows of wire on top are Switch Live, the MCB Live comes at the bottom and is looped to the other 2 switches, but i'm seeing both left & right side got MCB Live coming in, so my question is why is there 2 Live + 2 Loop wires in the switch?
