View Full Version : UK PAT Testing

I've just been informed that the 450 failed its electrical test and I believe the 850 will also.

It failed on "earth leakage". I aim to find out more and come back as this is not my area but we ave experienced getting small shocks in our truck from time to time and it seems to be 15 Volts flowing from somewhere.

More to come...

We were getting zapped by a set of racks back in the day; turned out to be an imbalance between the two hot legs, so the neutral was carrying the imbalance load. Then, the neutral and ground were swapped on one of the twistlock power connectors. Thus, voltage on the rack rails as compared to the other grounds in the system.
