All the proposals for the 2029 NEC are in and ready to be debated, they can be viewed with a free NFPA online account. One of them is to make a change in article 210 to allow a loads under 1440VA to be served by a 240V L-L receptacle in a residence (dwelling).
It was allowed long ago, and its probably often overlooked and violated with small window AC units and heat pumps. I think all the GFCI/AFCI tamper proof rules have gotten so strict there there may not be any danger from allowing a 15A 240V outlet or receptacle or 240V lighting outlet perhaps in multifamily buildings, dorms / hotels?
I recalled a post on here about a 230V British tea kettle and thought I would see what you all think?
Is 240V unsafe in a dwelling?
Or is that a outdated fossil of a by-gone era and the US should be modernized to allow 240V tea kettles, and small appliances?

6-15 and 6-20 receptacles have always been common to serve window shakers. I never heard they were illegal but the TR and AFCI rules may have made them so if it expanded to 240v circuits.
Originally most of the GFCI and AFCI rules only affected 15 & 20a 120v circuits.
What are they changing?
To be honest, since I have been retired about 25 years, I have lost track of a couple cycles. I was staying current with my code change CEUs up until around 2014.
