Just can’t get my head around which Code section applies.
An air handling unit with two electrical “heating circuits” each has a minimum electrical circuit ampacity and corresponding overcurrent rating. Is it correct to simply add the two values together to obtain the branch circuit feeding the two daisychained supplementary overcurrent devices.
