quess the fault

For those not conversant with the tester
3 lights =240v
4 lights=415v

Supply to dist board was 3Ph and N

Socket had worked for years before apparently blowing up someone's laptop

Harmonised jointed to old colours submains type major cockup?

No one could be stupid enough to connect it up so wrong in the DB surely?

S'pose it could be an O/C neutral on the DB, but I reckon you'd notice that pretty quickly

Nice to see someone else with a proper approved voltage indicator

Rf you let me down
I thought you would get it.

No one has worked there it just happened overnight.
Damn, did you just add that last bit

 

[RF Lighting]

I thought you would get it.

So did I

Do you know the fault?

I'm off to the pub with a pen and notebook to work this out

What did you hit your thumb with?

if that's true, I'd guess a floating neutral either recently happened or a compensating load on another phase has recently been removed.

what else is on that circuit? surely not just one socket?

It was brown paint from the fence.

You would not beleive what happened after I fixed it though

It was a 36 way board but the building was not used, so it went unnoticed till they used that one socket
