no supply earth and mounting box too small

[stephenc979]

im new here so hi everyone
i am just finished decorating my daughters bedroom and bought a chrome 3 bulb spotlight and chrome dimmer switch to finish it off

the dimmer is wired up and works fine but i cant push it back into the mounting box, the instructions say the box needs to be 10mm below wall level and its about double that, is there anything i can do?

Also the old light has no supply earth and with the new fitting it is all handy to wire up but the instructions say a supply earth is to go to one of the teeminals, what can i do?

Thanks in advance, stephen
