Need some help on an issue. I built a house in Waterford Falls in Frisco and was told by an electrician that we are required to have 7-10 open slots in the breaker box. I looked in mine and there are (0) slots available. WHat if I want to add an additional outlets or such. If someone has a code book, can you please look this up and let me know. This is costing us as residents $700.00 to add in a new box.

I find nothing in the N.E.C addressing extra capacity. N.E.C. Article 384-15 says you cannot have more than 42 overcurrent devices other than mains installed in any one cabinet, panelboard, or cutout box. Art. 110-12 says unused openings shall be effectively closed to afford protection substantially equivalent to the wall of the equipment. Art. 408.15 also addresses the number of over current devices on one panel board as 42. For these purposes a 2 pole breaker is considered 2 overcurrent devices; a 3 pole is considered 3 over current devices. Call 972-335-5580 with questions. Ask for an Electrical Inspector.
