Sections An inspector is your friend. Joseph F. Natasa Cvetkovic. The NFPA have a non-downloadable, non-printable, read-only version of all their codes available on their website.

I called the NFPA they said that the file was corrupted and gave me another free download.
What was the number you called? Mine has stopped loading at all it doesn't give a number to call. Do they ask for the code? I threw away the card so I don't have the code anymore. I know, lots of questions but if anyone else has this file the info is appreciated. I just bought the book, I haven't downlloaded it yet, but I'm thinking that I will throw it on to a memory stick.
People where having problem with Adobe 10, I don't know if that's been resolved!
One can fine and drop back down to another Adobe version. From the flier is says "This Feature rich format supercharges Code Referencing By enabling you to search, print, copy and paste, bookmark, and add notes at the touch of a key" I beleive from reading in the fine print they use your MAC Address not exactly said of the computer you download it to.
So I don't know about how they or you will handle that. Everything that can get on the internet has a MAC address. Questions 1. Many lighting control devices, such as an occupancy sensor, require low levels of stand-by current for proper operation.
In many installations, the equipment grounding conductor is the only available conductor that can be used as a circuit conductor for this low level stand-by current. The intent of this requirement is to be certain that the lighting circuit grounded conductor is available for the proper operation of the lighting control device.
This ensures that operation of the control device does not rely on connection to the equipment grounding conductor.
The section has been restructured to delete the exceptions and enumerate in positive language the instances where it is not necessary to provide the grounded circuit conductor at the switch location. The Section has been revised to require that a snap switch may be fed only from a single circuit unless it is listed and marked as suitable for use as a two-circuit or three-circuit switch. In the NEC, this Section permitted a multi-pole snap switch that was not marked as a two-circuit or three-circuit switch to be fed from multiple circuits if the switch voltage rating was not less than the line-to-line voltage of the system supplying the circuits.
This type of installation is no longer in compliance with the NEC. The purpose of this change was to ensure that switches used in twoand three-circuit installations have been evaluated and listed for the application.
Receptacles that are controlled by removing power must be marked with the appropriate symbol New energy management codes are being adopted that require automatic control of V, 15A and 20A receptacles. This new section in the code requires a receptacle to be marked with the appropriate symbol when the receptacle is part of a system that automatically removes power.
The symbol on the receptacle will alert the user that the receptacle will be automatically powered on and off. Locating these devices where they are accessible will increase the likelihood that they will be tested by the user. This section has been revised to allow the installation of listed receptacle assemblies in the top surface of a countertop.
The receptacle assemblies must be listed to ensure that they have been evaluated to function properly when exposed to conditions, such as liquid spills and splashing, likely to be encountered in countertop installations. A typical receptacle assembly for this application is a pop-up type of receptacle having a cover that is flush with the countertop when not in use and pops up when operated to reveal the receptacle.
Standard receptacles are often installed in a face-up position in seating and similar surfaces to accommodate the use of products such as cell phones and laptop computers. Receptacles in this type of installation are unprotected and exposed to conditions that may result in malfunction of the receptacle or possible hazards to the user.
This new section in the code requires the receptacles installed in these locations to be either listed assemblies or part of a listed assembly that will provide the necessary protection. Each of the assemblies specified by the code is a category of product that is listed and evaluated to a UL Safety Standard to ensure that the receptacles will be protected. These covers, commonly referred to as While-In-Use covers, provide protection for the receptacles both when a plug is inserted and when there is no plug inserted.
When an outlet box hood is used to meet this requirement, it must be listed and identified as Extra Duty. The Extra Duty covers are evaluated to more demanding test requirements than a standard cover. Previously, the requirement for an Extra Duty cover did not apply to one and two-family dwellings and only applied to enclosures supported from grade.
This Section has been revised to apply to all 15A and 20A receptacles installed in wet locations, regardless of the means used to mount the receptacle enclosures.
There was concern that covers were being damaged in residential as well as commercial installations. Tamper-resistant receptacles are required in dwellings, guest rooms, guest suites and child care facilities Three new sections have been included in the code to ensure the proper installation of ceiling suspended fans. The new sections describe adequate wiring space for conductors, provision of a cover for the outlet box and protection of combustible materials.
The new sections are similar to the requirements for the installation of luminaires in Section III, Article GFCI protection must be provided for tire inflation and automotive vacuum machines used by the public Tire inflation and automotive vacuum machines are heavily utilized and sometimes abused when provided for public use.
These machines are often located outdoors in locations such as gas stations and convenience stores where they are exposed to damp and wet environments. These conditions result in the potential for an electrical shock hazard to occur. This section in the code requires GFCI protection for vending machines.
When the vending machine is cord and plug connected, the GFCI protection is provided as part of the plug or is located in the power supply cord within 12 inches of the plug. A GFCI identified for portable use provides all of the features necessary for protection of personnel when used with portable equipment.
Vending machines manufactured or remanufactured prior to January 1, must be connected to a GFCI-protected outlet. Isolated ground receptacles may not be installed in the patient care vicinity of a health care facility. The concern is that the redundant grounding required by Sections Isolated ground receptacles may be used in other areas of a health care facility. Receptacles at patient bed locations that are supplied by the critical branch circuit are required by The receptacles on the critical branch circuit must also indicate the panelboard and branch circuit number that supply the receptacles.
The receptacles on the critical branch circuit must be identified and must also indicate the panelboard and circuit number that supply the receptacles. This section also provides installation requirements regarding connection of the receptacles to a branch circuit as well as information on connection of the receptacle grounding terminal.
An RV site with a 50A receptacle must also be equipped with a 30A receptacle This section has been revised to require a V, 30A receptacle to be provided at an RV site that is equipped with a 50A receptacle. This new requirement is intended to address the use of adapter cords.
In temporary installations, This section has been revised to permit the use of listed cord sets or devices that incorporate GFCI protection.
Several revisions were made in this Article in the NEC. Specific require ments for the cords and cables are in section Subsections A 1 , 2 and 3 have been rearranged in the NEC.
A 1 requires at least one V, 15A or 20A receptacle on a general purpose branch circuit to be provided not less than 6 feet or more than 20 feet from the inside wall of a permanently installed pool. This requirement previously only applied to dwelling units but now applies to all installations. A 2 has also been revised to delete the requirement that receptacles for circulation and sanitation must be a locking configuration.
In addition to the requirements in Article Part I, storable pools, spas and hot tubs must meet the electrical installation requirements of Part III.
Previously Part III only applied to storable pools. PV circuits are permitted in cable trays inside buildings. Flag for inappropriate content. Related titles.
