It's a "Classic" missing earth..... (But is it THE most common fault?).

[SPECIAL LOCATION]

From Tuesdays swapping a CU job....
Long lead earth continuity testing to the metal faceplate of 2x switches both gave an open circuit reading...

Opened up and what do we find.. A nice earthed plastic back-box, with a no-earthed faceplate!!!

Made me wonder..
Is this the most common no-earth metal accessory fault?

Or is it another common, cut the CPC's off in the back of a light fitting, (e.g. wall / downlight), problem?

Or can someone else nominate another 'No-Earth' common fault, need to resolve problem??

Probably, along with no CPC
