Togol, not only did I know that, I used to purchase them when they were Wigginton's. But now I prefer knopp, for the compact size of it. Been using those for years. Also I have had zero training for working on 600 volts. I don't attend any of those day long crummy seminars that certify you in cable splicing after attending. Some of my former hires have gone, and sat there for one day and now call themselves cable splicers on the resume. I think that stinks, and since I haven't had proper training in over 600, I would not allow myself near to it period.
