Ok so why is it that EVERY new construction neutral and ground is double lugged. Is this now approved and allowed in new constructions ?

“ Double tapped neutral ” is a slang term used when 2 neutral wires (the white wires) are terminated under the same screw on the neutral bus bar. This has been an unacceptable practice for many years.

Grounds are OK. The neutral lines 1 wire per hole.

Doubling on grounds have been acceptable.

As mentioned neutral conductors require a single hole in the bus bar for each conductor. EGC’s can have more than one if the bus bar is so listed. There should be a sticker on the inside of the cover or panel enclosure that states how many EGC’s are permitted in a single hole.
408.41 Grounded Conductor Terminations. Each grounded conductor shall terminate within the panelboard in an individual terminal that is not also used for another conductor.
Exception: Grounded conductors of circuits with parallel conductors shall be permitted to terminate in a single terminal if the terminal is identified for connection of more than one conductor.

Thanks Robert that helpful
Oh my, I just looked closer at pic 1. I see what appears to be a little intermingle of neutral and ground
And neutral and neutral and neutral.

Just wanted to point out that the neutral and equipment grounding conductors are on the same bar.
I wanted to make sure the OP noticed that flaw as they may have when encountering the double lugging
If this is a service panel then the two are permitted on the same bus bar. The OP didn’t say if it is or isn’t.

You’re The Best!
Thanks for the clarification. So if it is the first disconnect it is allowed.
Never practiced this method always kept it separated. Good to know. When in doubt I trust Mike Holt. 
I hope they don’t see this all the time.
