Codes I feel need the boot or changed?
210.63 needs to be changed to at least 50', maybe even 75'. What HVAC contractor only carries a 25' extension cord?
210.4(B) needs to go. Drives me crazy when I start a new project and the plan has circuits in one room scattered all over the panel. Extra neutrals/larger conduits cost extra money.
210.8(B)(5)...There should be an exception for a refrigerator receptacle within 6' of a sink requiring GFCI protection. Perhaps a single outlet for that situation would work?
422.51 should have an exception for receptacles installed inside say a lunch room (not outdoors) for vending machines.
Get rid of the Zone classifications for hazardous areas altogether.
Luminaire???? Did we really need to rename a light fixture?
My biggest pet peeve....Roof Top Units not having a built-in disconnect :rant: Some manufactures offer it as an option, just make it a rule that they need to have the disconnect built in!
IMO, ALL HVAC equipment should have a built-in disconnect. Finding space on these mini-split systems, or a small air conditioner installed on the middle of a commercial roof with no wall nearby to mount a disconnect drives me nuts!
End of code rant
