Rule 3. Additions or modifications to an existing installation shall be made in accordance with this Code
without bringing the remaining part of the installation into compliance with the requirements of this Code.
The installation shall not create a violation of this Code, nor shall it increase the magnitude of an existing
violation.
What part of 210-52(b) and 220-4(b) do we want to discuss?
210-52(b) Small Appliances.
1. In the kitchen, pantry, breakfast room, dining room, or similar area of a dwelling unit, the two or more 20-ampere small-appliance branch circuits required by Section 210-11(c)(1) shall serve all receptacle outlets covered by Sections 210-52(a) and (c) and receptacle outlets for refrigeration equipment.
Exception No. 1: In addition to the required receptacles specified by Section 210-52, switched receptacles supplied from a general-purpose branch circuit as defined in Section 210-70(a)(1), Exception No. 1, shall be permitted.
Exception No. 2: The receptacle outlet for refrigeration equipment shall be permitted to be supplied from an individual branch circuit rated 15 amperes or greater.
2. The two or more small-appliance branch circuits specified in (b)(1) shall have no other outlets.
Exception No. 1: A receptacle installed solely for the electrical supply to and support of an electric clock in any of the rooms specified above.
Exception No. 2: Receptacles installed to provide power for supplemental equipment and lighting on gas-fired ranges, ovens, or counter-mounted cooking units.
3. Receptacles installed in a kitchen to serve countertop surfaces shall be supplied by not less than two small-appliance branch circuits, either or both of which shall also be permitted to supply receptacle outlets in the same kitchen and in other rooms specified in Section 210-52(b)(1). Additional small-appliance branch circuits shall be permitted to supply receptacle outlets in the kitchen and other rooms specified in Section 210-52(b)(1). No small-appliance branch circuit shall serve more than one kitchen.
220-4(b) Inductive Lighting Loads. For circuits supplying lighting units that have ballasts, transformers, or autotransformers, the computed load shall be based on the total ampere ratings of such units and not on the total watts of the lamps.
Joe,
Would you mind commenting on the situation I described above.
Thanks,
