Retired Electrical Contractor, specialized in installing factories to make corrugated board, box plants. When my company was young we wired every kind of machine you can think of, I enjoyed working along side with the Millwrights and steam fitters...they taught me a thing or two.
My specialty was AC DC motor controls and power distribution. Factory moves were a favorite. I've taken machinery out of 1/2 the US at one time or another and installed it on the West Coast.
Outside of a hitch in the USMC, electrical work is all I've done since 68 when I graduated HS. Roped houses and apartments back then...hated every minute of it.
