I know how you feel belive me. I did my '46 Panel with a kit from EZ wire and me and electricty do not get along at all. I had to call a guy to come put in a switch and two outlets in my kitchen when I remodeled it. The only thing I can tell you is just what Trucknut did, take it slow one system at a time then take a deep breath and turn the key. I'm sure you did fine just like mine turned out and I'd never done anything like it before.
OH, if you can get one a CO2 or Halon extinguisher does not leave a mess just in case you have to use it
Hey I just noticed, how come its us older guys that are so nervous about doing these kinda things for the first
