Question: I have a 200amp, 120/240volt, single phase service supplying a "all-in-one" panelboard with 200/2 and 100/2 feeder breakers. Is the requirement of NEC 690.64(B)(2) applies to dwelling units, or this section only applies to photovoltaic systems?
NEC 690.64(B)(2) requires that each feeder overcurrent device for a dwelling unit shall be rated not greater than the ampacity of the feeder conductors. This requirement applies to all single-phase dwelling unit services, including those with 200/2 and 100/2 feeder breakers. Flag for review
