Bathroom wall light connection - earth loop problem

[CJDHRED]

I've one final light to fit in a new flat and have discovered along the way various permutations of wiring in the wall cavities - this one's stumped me though.

Purchased light fitting itself has wires for L, N and E.

Wall has two L's and N's, each connected to L and N in wall connector block i.e. two L's into one point on connector block and same for N's. Simple enough - connect corresponding light wiring to relevant point on connector block.

However, where normally the same would apply to E's, this time there's four E wires from wall, with two each connected to seperate ends of another connector block with no connection point for E wire on light fitting ; something I assume I can't simply ignore. Was planning to try and connect the light E wire to one of ends of the above but three wires squeezed into one end doesn't sound quite right.

Any guidance greatly appreciated on this last hurdle. Thanks.

They may be earths from another circuit or a place where supplementary bonding conductors are connected. These must all stay connected together as they are. Are some of the wires much thicker than the other ones?

edit: You would need to add another earth conductor to connect to your light fitting from those earth cables.
Also, is that fitting designed for use in a bathroom?

Just had a further look and you're suspicions are correct - two of the E wires are very thick at one end (thin at other) and yes, this is a bathroom light.

Please could you clarify how'd I'd add another earth conductor to the light earth wire ?

I'm presuming if I left the thick E wires as is, re-connected both the thin ones to another block and then attach the light E wire to this, this would be the wrong move ?

Thanks.

Yes, wrong move. All earth cables must stay connected together. They provide the safety earth bonding in your bathroom.
You need to add another earth wire one to run to the new light fitting.
Get a bigger connector block if the existing one isnt large enough.

OK, all earth wires conected together and light up and on before darkness curtailed efforts.

Thanks very much for your help on this one - appreciate your time.
