Had a call
For sometime the owner was getting shocks off the dishwasher if they touched the sink at the same time.
Tested 103v between the 2
Pat tested the dishwasher found live to metal 0.63 ohms traced fault to moulded plugtop replaced plug all tested fine with over 500M
now the problem
I Still have the 103v I tested by hand and there is defiantly a tingle
Tested the ring main at the CU
L-N >500M
N-PE >500M
L-PE starts at 360M but rises to >500M in seconds
Now i realise L-PE is lower but its still well in
The fault is on the ring as the fault is only there when that mcb is live
Before i start taking it apart and check each cable any ideas
