I wire the earths to earth terminal in the backbox. I also connect an earth from there to the face plate, if it's a metal face plate. I terminate the earths to the face plate and again from there to the backbox.
Always told most important part of an electric circuit is the earth!
hi, You should take earths(CPC's) from cable direct to accessory front plate term. it is not required by regs to earth back to box ( another NICEIC myth) you can of course if you wish do so in which case as you have another term you could use that to link a pigtail/flylead to back box term.
Now watch the action!!
for those who want to disagree i would direct them to :
page 117 of current 16th book reg # 543-02-02 (vi),
543-02-07 & 543-02-09.
So for instance you can still run circuits in metal conduits &/or trunking without an earth wire as long as you connect from the box to any fitting with a fly lead & are capable of proving continuity of metalwork, not worth the hassle but you can do it! I love the regs....
