Incident overview
In an electrical room at a public festival, underground cable routed power to sub distribution panel boards. Each board contained a combination of armoured and non-metallic sheathed cables. The insulation around one of the mechanical conductor splices deteriorated over time, eventually contacting the metallic equipment enclosure, and created a ground-fault to bonded-to-ground enclosure.
