If Trick 440 still needs help with the calculations and the Arc Flash values, I was at a seminar in Grand Rapids and talked to Dave Vallier (a highly qualified engineer from Bussmann) and he can help you out here in SE Michigan. Bussmann is very active with IAEI and I would recommend contacting Dave at this address: dave.vallier@cooperindustries.com He suggested I convey this message to you.
