CHAPTER 31. Equipment covered in Section 1.1.2 of the ASME A17.1 Safety Code for Elevators and Escalators. Below is a summary of these new 2017 NEC sections: In order to comply with these requirements a chain of events must occur. Checking off the items on this list will help you to ensure that you have met important national elevator codes. 615 0 obj <> endobj Chapter 29 Plumbing Systems. The Uniform Building Code requires two-way communications between the central command center and the elevators, each elevator lobby, emergency power rooms, and by entries into enclosed stairways (Section 403.5.3). Firefighters can then use portable telephone handsets in combination with the jacks and cabling. endobj 6 0 obj The elevator controller manufacturer must determine the required elevator controller SCCR as stated in the elevator controller specification and provide an elevator controller SCCR that is equal to or greater than the available fault current thats indicated in the design documents where there are multiple elevator controllers at different locations. Posted Under In some cases, it may require a means to test the shunt trip operation or have one contact operate the shunt trip of more than one elevator. Many new buildings are incorporating an elevator design that does not include an equipment room (sometimes called machine room-less elevators). Machine room-less elevator installations incorporate the elevator controller and often the primary disconnecting means in a convenient package that is located within the elevator shaft. x g*P1S0@ _j !wU!5corVIaVC.|<= Traditionally, the electrical system design engineer has given little attention to the elevator controller. The Safety Standard for Belt Manlifts is the ASME A90.1-2015. For instance, a typical elevator controller may traditionally have SCCR ratings from 5 to 10 kA. It is mandatory, as in the car, that these items have a separate, dedicated branch circuit, and the required lighting is not to be supplied through a GFCI. <> stream Section 620.37 re-emphasizes that only wiring used in connection with the elevator is permitted within the hoistway, machine room, control room/machinery space or control space. ELEVATORS AND CONVEYING SYSTEMS. endobj NEC Article 620 Part V, Traveling Cables, is driven by two major issues. First, you'll need to install lighting in the elevator equipment room (Photo 1) and shaft pit (Photo 2). If you specify a rescuvator, you must also specify a disconnect switch with an auxiliary contact that opens when the disconnect arm moves to the open position, but stays closed when the OCPD trips. Chapter 30: Elevators and Conveying Systems, Chicago Building Code 2019 \ A&&'70 Sk*EZfm}1csX)9R5R8jW5J)+5s!?>)%Xv}/)_x>j@WCw[ The elevator equipment room that serves a hydraulic elevator is almost always located on the lowest floor adjacent to the elevator shaft. So, we see that for elevator work, greater fill is allowed. The new ADAAG guidelines now require that emergency power be available to elevators that have four or more stories of travel above or below the accessible floor [4.1.3(9)(1)]. Another location that requires a separate branch circuit for lighting and receptacle(s) is the hoistway pit. Another important electrical system design listed with high combination SCCRs. GFCIs in Elevator Pits, Receptacles and More - Electrical Contractor Supports for cables or raceways in a hoistway or in an escalator or moving-walk wellway or platform lift and stairway chairlift runway must be securely fastened to the guide rail, escalator or moving-walk truss, or to the hoistway, wellway or runway construction. You must locate this key switch at the main lobby or at the building fire command center. While machine room-less designs have been commercially available for many years, their use may still be unknown to some AHJs. Motors for traction elevators were traditionally DC or synchronous, but new installations use AC motors and VFDs for speed control. The Safety Code for Existing Elevators and Escalators is the ASME A17.3-2015. You need to Subscribe to continuing reading. You are a subscriber that needs to Sign In. Traction elevators are typically faster and more energy efficient than hydraulic elevators, and are often used for high-rise buildings. For instance, one method to reduce the available fault current is to add an isolation transformer ahead of the elevator controller. endobj Traction elevators are typically installed in a bank of elevators where fused switches, or circuit breakers in a panelboard are located in the machine room serving the bank of elevators. In addition, the shunt-trip voltage must also be monitored by the Fire Alarm System. It can seem such a tedious process, especially since elevator code falls under many different bodies. endstream Other codes and standards interact with the NEC, and it is necessary to see how they all work together in order to create safe and compliant elevator designs/installations.

P Escalators, moving walks, conveyors, personnel hoists and material hoists shall comply with the provisions of Sections 3004.2 through 3004.4. While the provisions highlighted here from NFPA 13 are relatively straightforward there is added complexity of elevator codes as well as local amendments in many jurisdictions. The elevator rails, like the ground system of the entire building electrical structure, are to be bonded to the lightning-system ground electrode so these all remain at the same potential even during a lightning event, ensuring side flash does not occur. Where a feeder powers more than one elevator, you need selective coordination; the OCPDs must be series-designed so a fault at one of the elevators will be cleared by only the OCPD serving it. Part X, Emergency and Standby Power Systems, is simple and straightforward. Some jurisdictions will have special provisions that modify power shut down provision or they will not permit sprinklers at all out of concerns for first responders utilizing the elevator during a fire. Emergency and Standby Power for Commercial Occupancies With the new elevator controller requirements, more attention will be focused on the elevator system. These circuit breaker selective coordination tables can be used to identify the maximum fault current that a pair of circuit breakers can selectively coordinate. The locking capability is important so during maintenance, the equipment will not be inadvertently energized. Motor feeder short circuit and ground-fault protection must be as required in Article 430, Part V for all motors. A section on branch circuits for car lighting, receptacles, ventilation, heating and air-conditioning contains a number of important provisions. This is typically accomplished via a shunt trip device. hb```\@(` hx[ B8yXCE700t{nB(u5jB[c~(]cDPlu5LJa9[\] Td2V Y 1&u+Ho a`@&>,3/b1 2?CVZL>10Y{gEfM 7Rwsg $<05hl B^( Chapter 30 Elevators and Conveying Systems. However, there are certain concealed spaces and special situations, such as elevator hoistways and machine rooms where sprinkler protection can be omitted. PDF NFPA 70: National Electrical Code (NEC), 2014 Chapter 2: Wiring and The panel further clarified that the marked SCCR value must be adequate for the available fault current to ensure a safe installation. Proper selective coordination in a multi-elevator installation on the same feeder ensures if one elevator develops a fault, the other units will not be shut down. endobj If the building has emergency power available, use it to supply the cab lights. Rules of the Indiana Fire Prevention and Building Safety Commission - DHS Here is the current code where (a) was added to limit the NEMA Type 4 to elevator electrical only. This is the area within the hoistway beneath the car, and there are occasions when elevator technicians have to work in this area for maintenance and troubleshooting. NFPA members and public sector officials may submit a question on an NFPA code or standard. The ASME A18.1-2017 is the Safety Standard for Platform Lifts and Stairway Chairlifts. All rights reserved. If a smoke detector goes into alarm, it signals the elevator to go into Fire Recall Function, at which point the controller directs the elevator cab to travel to its pre-programmed designated landing, open its doors, and remain stopped there until the alarm clears. Home Articles Elevator World June 2012 Issue NEC Article 620: Elevators, Part 2. Power for the elevator controller must first enter a lockable safety disconnect device, located adjacent to the door of the equipment room. David Herres holds a New Hampshire Master Electricians license and has worked as an electrician in the northern part of that state for many years.

CHAPTER 27 - ELECTRICAL . This is important as the tradition of using only time-current curves for the analysis of overcurrent device operation is usually not sufficient since the time-current curves traditionally stop at 0.01 second (not time zero). NEC 620.62 requires the elevator disconnecting means (fused switch or circuit breaker) to selectively coordinate with all supply-side overcurrent devices. Convenience receptacles and lighting for maintenance purposes are required at the base of the pit and, in some instances (elevator manufacturer dependent), at the top of the elevator shaft. <> stream Where multiple driving machines are connected to a single elevator, there is to be one disconnecting means to disconnect the motor(s) and control-valve-operating magnets. Corporate Office Electricity is often one of the initial services to fail during a storm. It is important for design engineers to communicate this with the architect and owner during the design phase, as it will impact space needs elsewhere in the facility to accommodate electrical equipment. endobj 2.
