Dutch of the Elm:
Hi Dave,
Has the continuity of the trunking been checked, and is it bonded to Earth?
I'm assuming it is metal trunking..
Seems like there was a significant overload on L1 but I'm not sure that this is related. What type cable comprises the circuit?
Trunking system is well constructed and all well linked with earth straps to DBs, it is indeed steel containment (300x300), all single 6491x conductors, TPNE. 25mm2 live conductors, 16mm2 CPC. Protection is 63A IEC157 MCCB no earth leakage protection at source.
