I was reminded of this by the power saw thread.
In Feb 2011, two horses were killed at Newbury racecourse by part of the paddock becoming live after heavy rain.
I wondered what the outcome of the (electrical) investigation was but can not find anything online. Reports ore conflicting - some say it was an old 240V cable directly buried for a long time which had deteriorated, others say it was an 11kV cable.
Anyone know?
