Not mine but a colleague in Dundee.

Ok. Question... You are installing a new 12 way board and you have an ring RCD trip after installing. Of course this didn't show up during dead testing did it ?.

Do you...
A: Disconnect everything. Plug in one by one and isolate a faulty food mixer.

Or:

B: Move the ring to a new 32a breaker on the din rail but not the busbar and feed that with a bit of red 6mm from the input of the nearest RCD. N to non protected bar. Then charge extra for fault finding

 

[Dustydazzler]

Depends how much I charged for the board change in the first place ...?

option 2 is leaving an RFC non rcd protected, or am I misunderstanding?

if it didn’t show up on dead tests, it’s something plugged in, or the fault has been introduced during the board change.

 

[WallaceP]

Hmmm really depends on what colour my mood ring is...

 

[littlespark]

Oh... i just read its in Dundee... check the attic for horticulture
