SIGNIFICANT CHANGES FOR THE 2011 N.E.C.

90.5 Fine print notes are now called informational notes.

100. The term grounding conductor has been deleted.

250.52(A)(2) the metal frame of the building is permitted as a grounding electrode where connected to the earth by one or more of the following methods.
1: at least one structural member that is in direct contact with the earth for 10 feet or more with or without concrete encasement.
2: the hold down bolts securing the structural steel column connected to a concrete encased electrode that complies with 250.52(A)(3) located in the support footing or foundation.

                                                          CHAPTER THREE

300.4(H)  a listed expansion/deflection fitting or other approved means shall be used where a raceway crosses a structural joint intended for expansion, contraction or deflection, used in buildings, bridges, parking garages or other structures.

300.11(A)(2)  NON FIRE RATED ASSEMBLIES. Where independent support wires are used, they shall be distinguishable by color, tagging, or other effective means.

310.10(H)(6) where parallel equipment bonding jumpers installed in raceways, they are required to be sized and installed in accordance with 250.102.

310.16 has been re-numbered to 310.15(B)(16) some of the ampacity values have been adjusted in an effort to harmonize with the Canadian Electrical Code.

314.27(C) at single or multi family dwellings, spare, separately switched, ungrounded conductors at ceiling mounted outlet boxes (in a location acceptable for a ceiling fan) require an outlet box listed for sole support for a ceiling suspended fan.

338.10(B)(4)(a) Type SE Cable.  Where installed in thermal insulation, the ampacity to comply with 60 degree conductor temperature rating.

348.42 Couplings and Connectors. 90 degree connectors shall not be installed where the angle connector itself will be concealed.

                                                     CHAPTER 4

400.5(A) Ampacity tables for cords and cables. Temperature correction factors fro table 310.15 (B)(2)(a) corresponding to the temperature rating of the cord to be applied to the amp[ampacity from table 400.5(A)(2).

404.2(C) Generally when switches control lighting loads from a grounded general purpose branch circuit, the grounded circuit conductor for the controlled lighting circuit must be present at the switch location.

406.4(D)(4) arc-fault circuit interrupter protection is required for replacement receptacle outlets where a receptacle outlet is supplied by a branch circuit that requires AFCI protection elsewhere in the code.  (EFFECTIVE DATE JANUARY 1 2014).

406.4(D)(5) listed tamper resistant receptacles are required for replacement receptacle outlets where a receptacle outlet is required to be tamper resistant elsewhere in the code.
