If we are talking a 2.5T AC unit, (2) Small Appl. (1) Laundry and 3VA per sq ft for the 720 sq ft space…and everything else is gas…hmmmm
Sm Ap - 3,000VA
Laund - 1,500VA
Apply the factors and you have - 4,281VA in G & L Loads
now lets just say its a 2.5Ton AC unit ( 4,400VA ) 100% mind you
Add oh…heck atleast a fridge at 1,400VA ( appliance)
Giving you 10,081 VA divided by 240V = 42A Demand
NOW…again with all that said…if this is a Single Family Dwelling it should be ( New Costruction ) minimum 100A…but alas…guess you could find anything anywhere…
****[FONT=Times-Bold]size=2 One-Family Dwelling. **For a one-family dwelling, the
service disconnecting means shall have a rating of not less
than 100 amperes, 3-wire.
Now their are exceptions for other loads…under 230.79 but if again we are speaking of a single family dwelling…100A is the minimum.
