I have the 3VA as far back as 51, I think the 2 small appliance ckts appeared in65 I don't see it in 210 in the 1962 but I will look again
EDIT OOOppps
The 1962 has a new section 220.4(h) small appliance -dwelling units.
It sets demand loads of 1500 for each 2 wire BC for aplliance circuits it does not specify the minimum number required or the minimum ampacity. It looks like it could have been a 15A BC.
Again nothing in 210.
