Trumpy, thank you I would prefer to see my kids grow up.
lighthouse, the link for "sign web" was just the info I needed along with article 600.
I just got back from the first night of working on this, the original installation was very professional all the GTO cord was in 1/2" flex to the last point possible. The transformers where 277/7500 volt. Mostly removal had to refeed one "tube" but that was no problem.
Thanks for the help (and warning) that's why I asked questions here you can always get some help.
