An unregistered 'electrician' had relocated the consumer unit and not connected the earth bonds
This is why only competent registered electricians should be used.
The minimum gap allowed on the top of a consumer unit is 1mm square.
Replaced consumer unit and crimp joints encased in PVC trunking.
Before - No earth connection, single insulated cores, no armored glands etc.....
After - All up to standard
Before - No earth connection (SNE terminal empty)
After - Both properties earthed, all earth connections labled and tidy etc....
No RCD, an unreliable earth and wooden board etc....
They where unreliable in the 60's when fitted but have since failed
Installation fully upgraded with new earth stakes RCBO protection on all circuits and metal consumer unit.
