I'll do my usual quick explanation at this time of the morning (until the experts come up with the technical side).
1 - 20years and I&T several times and no-one noticed?
2 - Out of balance of the three phases and fairly constant loads would provide a nice stable centre point. Stores tend to tun everything on and off at regular times, so quite feasible.

I'll let the experts pop up now.

I'm not an expert but I would say its more a case of loss of the OP......

Has the OP 'Chadwell' withdrawn his query or is there a problem as Normcall's name appears as the first entry?

Damm, you lot are just too slow.
It was about a 2 storey store that was downsizing and when they went to separate, the main buss bar chamber was not connected to the main supply intake neutral.
Maybe they found it!

Nah, the missing neutral link from the main switchfuse.
I expect it was that black wire instead of a pretty blue they expected.

Sounds to me more likely that there was a NE fault some where on one of the circuits giving a return path. I know you said it has had an I&T but that doesn't mean they did the test by the book or that they repaired any defects present at the time?
