Tomo Posted March 11, 2006 Share Posted March 11, 2006 Odd that he uses W instead of the Ω symbol.The minimum insulation resistance should be 0.5MW and tested at 500V dc.(Emphasis mine) It's done throughout, which will cause confusion as there are places where it really could mean power in Watts, as opposed to resistance or reactance in Ohms.
