Such rooms and spaces that are also part of a dwelling unit are not sleeping units.
This document is to clarify the requirements for signs to indicate automatic generator transfer required in the National Electric Code (NEC), NFPA 70-1999, referenced standard in the Building Code of New York State (BCNYS) Chapter 27 and whether those requirements are also applicable to buildings constructed in compliance with the Residential Code of New York State (RCNYS). The answer is Yes. NEC section 700-8(a), Emergency Sources, states: A sign shall be placed at the service entrance equipment indicating type and location of on site emergency power sources. This section part of Article 700- Emergency systems. Section 700-1, scope, states n part: emergency systems are those systems legally required and classed as emergency by municipal, state, federal or other codes, or by any governmental agency having jurisdiction. Additionally, Article 701 – Legally required standby system, section 701-9(a), states: A sign shall be place at service entrance equipment that indicates the type and location of on site legally required standby power sources. And Article 702 – Optional Standby Systems, section 702-8(a) states: A sign shall be place at the service entrance equipment that indicates the type and location of on site optional standby power sources. Each of these sections has an exception for individual unit equipment, which is battery backup lighting fixtures and similar single unit power supplies. With respect to the RCNYS, section E3301.2, scope, states in part: The omission from these chapters of any material or method of construction provided for in the referenced standard NFPA 70 shall not be construed as prohibiting the use of such material or method of construction. Electrical systems, equipment or components not specifically covered in these chapters shall comply with the applicable provisions of the NFPA 70. This requirement for generator signage at the service entrance equipment is applicable to all buildings, which have an automatic generator transfer switch (optional standby power), legally required standby power and emergency systems. This requirement is important to emergency responders when they are trying to kill the power to a building.
National Electrical Code and Arc-fault Circuit-interrupter Protection
This document provides information with regard to the referenced version of the National Electrical Code (NEC) and to the requirements for arc-fault circuit-interrupter protection in BCNYS Chapter 27, which refers to NFPA 70, the National Electrical Code (NEC) and RCNYS Part VIII, Electrical. What is applicable version of the NEC for enforcement and why? The BCNYS, chapter 27, references the 1999 version of NFPA 70 (NEC). Electrical inspections shall provide for conformance to the referenced version and not to newer versions. Each version of the reference standards has to be approved by the Fire and Building Code Council (Codes Council) before it is effective. The inspection of electrical systems is the responsibility of the local code enforcement official. This provision is also applicable to electrical inspection companies who are third party inspectors. Are arc-fault circuit-interrupters required in residential buildings regulated by the BCNYS? YES. Chapter 27 of the BCNYS references the 1999 version of the NEC which in section 210-12, requires arc-fault circuit-interrupter protection for all branch circuits that supply 125-volt, single-phase, 15- and 20- ampere receptacle outlets installed in dwelling unit bedrooms (effective January 1, 2002). Are arc-fault circuit-interrupters required in residential buildings regulated by the RCNYS? The RCNYS is applicable to detached one- and two-family dwellings and multiple single-family dwellings (townhouses) not more than three stories in height with a separate means of egress. Part VIII of the RCNYS has specific requirements for electrical installations. Section 3301.1, entitled “Applicability”, provides that Chapter E33 through Chapter E42 shall establish the general scope of the electrical system and equipment requirements of this code. Chapter E33 through Chapter E42 cover those wiring methods and materials most commonly encountered in the construction of one- and two-family dwellings and structures regulated by the RCNYS. Section 3301.1 also states: Other wiring methods, materials and subject matter covered in the NFPA 70 are also allowed by this code. Arc-fault circuit-interrupters are not required by the RCNYS within the text of Part VIII and cannot be required by the inspector.
NEC Service entrance Length
This bulletin is intended to clarify questions regarding the maximum length of service entrance conductors prior to the service disconnecting means and the maximum length of unprotected service entrance conductors concealed within a wall cavity in NFPA 70, the National Electrical Code (NEC) - 1999, referenced standard for the Building Code of New York State and in the Residential Code of New York State (RCNYS). NEC section 230-70(a) and RCNYS section E3501.6.2, each state: The service disconnecting means shall be installed at a readily accessible location either outside of a building or inside nearest the point of entrance of the service conductors. The code language does not limit the length of either exposed or concealed service entrance conductors. The intent is to provide a service disconnecting means that is at an accessible location as close as is practical to the point at which these conductors enter a building. Furthermore, these codes do not prohibit, nor limit, the length of unprotected service entrance conductors which are concealed in a wall cavity. NEC section 300-4(d) and RCNYS section E3702.2.2 and table E3702.1 state that where cables are installed parallel to the sides of rafters, studs or floor joists, cables shall be installed not less than 1.25 inches from the edge of framing member where nails or screws are likely to penetrate or shall be protected by a steel plate, sleeve, or equivalent at least 1/16 inch thick. This section is applicable to both edges of the framing member. As a practical matter, the location of the disconnecting means and the length of the service entrance conductors should be established by the designer and installer in consultation with the local code enforcement official prior to the installation. Some utility company specifications establish maximum lengths for service entrance conductors prior to the disconnecting means. These specifications cannot be enforced by a code enforcement authority because such specifications are not part of the enforceable rules and regulations of the State of New York.
Electrical Code Transition Policy
As of October 3, 2007 the effective date of adoption of the 2007 Codes of New York State. There was a transitional period from October 3, 2007 to December 31, 2007, in which design professionals may choose from the codes in effect previously or the 2007 New York State Codes, no mixing and matching permitted. This means that the application of the electrical standards will follow suit. For example: a designer may have chosen to employ the 1999 NEC for 1 & 2 family dwellings throughout this period, or the designer may have opted to use the 2002 NEC for 1 & 2 family dwellings and the 2005 NEC for apartments within multiple dwellings. After the close of business on December 31, 2007, the transitional period ended and it is now necessary to use the 2007 stand alone residential code or the 2002 NEC for one and two family dwellings and townhouses and the 2005 for multiple dwellings and all other building structures. There are substantive differences among these editions requiring attentive interpretation and application. Comparing the provisions of 210.12 from 2002 to 2005 is an example having to do with arc-fault. There are others. It is hoped that the adjustments will be made with the code cycles in the effort to move to one edition in the upcoming work, but that is not within the control of this office. Questions concerning this transition may be directed to this office. Sincerely, David P. Smith President The Inspector, LLC
