Hey Leland...
There is truth to this, however the union did not get it "passed" as it has always been in the code book and regarded as electricians work.
There were some companies trying to circumvent the licensing board to get this work "unregulated" as far as licensing goes so they could put anybody up on a roof to install these and then just have a licensed electrician do the final connections.
The union has simply pushed to keep this work for qualified, licensed electricians to install.
