Question for the residential contractors: For a typical apartment, let's say 2-bedroom, 2 bath, kitchen, living room, laundry utility room, it there a significant cost increase to specify only 20A circuit breakers, versus a mix of 15A for general lighting/receptacles keeping the required 20A for bathroom sink and kitchen appliance receptacles? Or is simpler to only have to provide one size romex to a jobsite?
Thanks for your input.
