Back to original question...yes it has dining recepticles and a fridge on it .before fridge and outlets its junctioned again to bedroom outlets..is a 70s home also..
Is it required to be on dedicated circuit in dining room 20amp?
Sorry sbout that,
In todays codes the dining room is concidered a SABC, and the fridge can be on with the dining room (just AFCI protected).
I will also say that if its wired as said, you don't need to change it, (grandfathered in), but you can not add to it either
220.14 Other Loads — All Occupancies. In all occupancies, the minimum load for each outlet for general-use receptacles and outlets not used for general illumination shall not be less than that calculated in 220.14(A) through (L), the loads shown being based on nominal branch-circuit voltages.
I assumed junction box here in this thread to mean outlets ..LOL
Section 220.14 applies only to those receptacles not covered by 220.12, Table 220.12 (read "a" and what it applies to under the table), see 220.14(J)1,2,3 which pretty much covers every receptacle and lighting outlet in the dwelling.
220.14 would however apply to the required GFI convenience receptacle installed at a pool for example.
There is no limit to the number of receptacles installed on a general lighting circuit in a dwelling. However, one 15A circuit is required for every 600 sq ft of living space, or one 20A circuit for each 800 sq ft of living space. A 2400 sq ft home would require four 15A circuits or three 20A general lighting circuits.
