In Canada 600 volt is used in industry 3 phase 4 wire is 347 to Neutral
It sure makes you think! Yesterday, I opened a 100A disconnect and had water dripping from the main supply conduit , down the back of the panel and pooling at the base. The agent asked if this was dangerous!
Thanks Roy! The video was sobering. I personally will not touch anything other than a 200 amp 120/240 system. I have had the distinct displeasure of having gone dead to ground and waking up in the emergency room! Opening any panel is dangerous.
Again thanks for bringing this to our attention.
