There are couple quirks I will say in here the netural conductors that bundled in each hole that is a no-no but for EGC c'est ok IMO it will be alot nicer if it have own grounding bussbar for this useage which I done all the time it cost little more upfront but in long run it look much neater plus what more .,,
If that area requied a extreal disconnection source it is very easy to swap over to 4 conductor set up.
Merci.
