can any one help me im wiring up 2 down lights but not sure what to do with the earth wires it says in the instructons this unit is double insulated and must not be earthed if there are any incoming earth cables they must be joined together and well insulated with tape this is to ensure earth continuity throughout your property i have earth wires coming in but the lights are wired from each light into the main wires coming through roof what will i need to do

 

safely connect earth wires together in a connector of some kind and push up in ceiling away from heat of lamp fitting

 

Tape the end up if there is only one

 

buti dont think i will manage to join them together because there wired apart and the roof been plastered

 

are they on the same ring - or a spur ?

 

are they on the same lighting circuit/switch

 

not sure what u mean they have wires coming from each light and are joined to the main wires that came trough the ceiling i have also lowered the ceiling

 

yes

 

Stick it in a connector m8.

 

how many lights were there before you done the ceiling and do they switch on together also is there only one cable at each light

 

Im not sure what your struggling with ?

You connect up the live and the neutral and just ignore the earths and tape/join them together for each light unit (treat as seperate units)

You not thinking you need to tape up each of your two units earths together are you ?

 

1 light and they switch on together

 

the live and neutrals are wired up lights are working but not sure what to do with the the earths it says join them to gether

 

if there is a single cable at each light and they switch on together then ther will be a jb in the roof or 2 switch lines at the switch where the earths should be connected to protect the cable put the earth into a connector at each fitting.

the light fitting should have a connector for the earth wire and there should be no visable single insulated wires outside of the down light connection box in the roof

Im an electrician join the earths together in a connector block, dont forget to use earth sleeve. You need to make sure you have continuity otherwise the protective earth system will not work.

Any more Qus?

the light doesnt have an earth connection as its double insulated and must not be earthed if there are any incoming earth cables they must be joined together and be well insulated thats what it says in the instructions

 

He meant the cable feeding the light m8.

 

so will i need to buy earth cable and try and feed the cable through the holes to join the to earths together

 

I guess one light is fed of the other.... join the two earths together where the feeds meet then just terminate the single earth on its own.

If you have anymore problems PM me your phone number and i will call you in the morning and explain it over the phone.

 

If there's one cable at each light then they've been jointed in the ceiling space somewhere,so just stick them in connectors m8.

 

sojust stick them in one of those clear blocks for each light and tape it up

 

Sounds ok i think.

 

so do i do each light separate or do i need to get earth wire and join them together

 

That’s the age-old question. The cable used to feel the lights should be what’s known as twin and earth.

External insulation will be either Grey or White.

old colours

Red = live
Black = neutral
No coloured insulation = earth

new colours

Brown = live
Blue = neutral
No coloured insulation = earth (cpc)

 

its the same as pic

 

Ok the wire with no colour is earth.

Dan

 

i know that but what do i do with it

 

Just connect the earths in the cable together, using a clear connector terminal. People used to just cut them off but we don’t do that anymore.

Dan

 

put some sleeving on it and then into a connector and tape up and if your still worried about it you will either need to have a earth loop impedence test done at each light or test for continuity from the earth at the switch or at the jb in the roof to see if you`ve got on earth at the light fitting.

got it done thanks everyone that gave advice

 

Nice one m8.
