Class A installer license from the electrical code elimination

SF 3719 eliminates the "Class A installer" license category from Minnesota's electrical code. The bill amends statutes to remove all references to this license type and repeals two definitions that previously described it. This directly affects electrical workers who held this license (though no new licenses have been issued since 2007) by formally removing the classification from state law. The change streamlines licensing requirements by removing an outdated category from the electrical code.
