Good morning,
Came across a strange one doing an EICR yesterday.
The fuse board is fed with two phases and one neutral...phases L2 and L3 are linked.
I'm looking for a coding or deviation.
As I see it, best way is it's unbalanced loadings with pressure on the neutral.
Worst way is two supply circuits with a shared neutral.
The spare phase is being used to supply a flat in the building.
Loading wise, it would be possible to link out all phases in the main CU, making it a single phase board...but that would only push the problem back to the intake.
Any suggestions please.
