Emergency and Standby Power for Commercial Occupancies A separate 120VAC, 15A circuit is required for cab lighting and accessories, and it must have its own local disconnect and OCPD in the equipment room as well. These conductors may be covered with suitable shielding for telephone, audio, video or higher-frequency communications circuits. In case of emergency, electricians, maintenance personnel and any elevator technicians called in to the premises should have ready access to the key. Status of normal power to the elevator equipment, elevator machinery and electrical apparatus cooling equipment where provided, . Here is the current code where (a) was added to limit the NEMA Type 4 to elevator electrical only. It is further stated that the disconnecting means are not to disconnect the branch circuits required in sections 620.22, 620.23 and 620.24. However, this can vary depending on building conditions and exterior grade. SPECIAL CONSTRUCTION. After reading this article, you should have learned: Which locations require sepa-rate, dedicated branch circuits Which branch circuits are not to be provided with ground fault circuit interrupter (GFCI) pro-tection Which locations must have one or more duplex receptacles Where overcurrent protection for hoistway, pit and machine-room lighting must be located How unsupported lengths of traveling cables are measured.

In Chapter 27, Section 2702.2.2, the code explains that where required, elevators shall be provided with standby power. Similar provisions are attached to elevator-car heating and air-conditioning disconnecting means, and to other utilization equipment. 13 0 obj You need to Subscribe to continuing reading. endobj The Safety Standard for Belt Manlifts is the ASME A90.1-2015. endobj If the building code does not require sprinkler protection based on occupancy, constructions type, size, or height then the elevator is also not required to be protected. Learn your best options for addressing this with your emergency phones. The code does not include design specifications or instructions like those found in installation manuals. A traction elevator's equipment room is typically located at the top of the building, directly over or adjacent to the shaft. The conduit alone can't act as the grounding means. 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. GFCIs in Elevator Pits, Receptacles and More - Electrical Contractor This room is to be secured against unauthorized access (kept locked). Furthermore, at least one 125-V, single-phase, 15- or 20-amp duplex receptacle is to be provided in each machine room or similar location. Unless a way was found to allow the elevators to run at full speed . All of these options and special wiring can be challenging depending upon the location of the shunt trip circuit breaker as well as who has responsibility for providing these additional options. While they certainly provide a convenient and accessible means for traveling up and down through a building they also create vertical openings in a building, increasing the potential for the spread of fire and smoke. endstream endobj startxref The light switch for the equipment room must be adjacent to the entrance door on the latch side. The branch circuit supplying these units is to be similarly dedicated, with the associated overcurrent device located in the machine room or similar location. The feeder OCPD needs to remain closed so the remaining elevators have power and continue to function.

Section 725.45 concerns the location of overcurrent devices and provides for feeder and branch-circuit taps, transformer primary side overcurrent device location and overcurrent device location at the input side of electronic power sources. Similarly, motor branch-circuit short circuit and ground-fault protection must be as required in Article 430, Part IV, for all motors. Elevator power disconnect (with utility feed marking) located in the machine room or other permitted location David Herres David Herres holds a New Hampshire Master Electrician's license and has worked as an electrician in the northern part of that state for many years. Also located in this room might be, but not limited to: exhaust fan, cooling unit (depending on local requirements and/or requirements set forth by the individual elevator supplier), lighting, voice and/or data drop serving the elevator cab emergency phone, elevator controller primary fused disconnect, elevator feeder shunt-trip circuit (i.e., shunt-trip circuit breaker), elevator cab lighting fused switch, and convenience receptacle(s). This situation necessitates some special arrangement, such as a shunt trip or a preaction system, to make sure that water does not flow in the elevator shaft until power shutdown has occurred. Furthermore, you can face huge, unnecessary fines if an inspector finds you non-compliant, so it is essential that elevator code compliance is something that you regularly think about and attend to. Codes - California As we have seen, a limited number of these are approved for elevator locations car, hoistway, pit and machine room. /Font <>>> Your IP: Since 1953, Elevator World, Inc. has been the premier publisher for the global vertical transportation industry. In addition, requirements for selective coordination and shunt tripping should be complied with as needed for the installation. 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. PDF Elevator Electrical Requirements A further requirement concerns elevator-car air-conditioning and heating. PDF Compliance with the 2017 NEC for Elevator Controllers Next, with multiple elevator banks, the controller will usually allow only one elevator at a time to operate, reducing the amount of emergency power required. Selective coordination is defined by the NEC as: Localization of an overcurrent condition to restrict outages to the circuit or equipment affected, accomplished by the selection and installation of overcurrent protective devices and their ratings or settings for the full range of available overcurrents, from overload to the maximum available fault current, and for the full range of overcurrent protective device opening times associated with those overcurrents.. In fact, an entire elevator system for a project is most often designed and specified by the architect who has little understanding of the electrical distribution system. You'll need to run telephone cables to the equipment room control panel, but the elevator supplier will take care of getting the cables to the elevator cab. This switch will ensure that the elevator won't descend into the elevator pit and allow maintenance people to work safely in the area beneath the cab. It is important for the design engineer to coordinate with the architect to determine the elevator manufacturer basis of design to determine if and when additional power and lighting is required. Compliance with the 2017 NEC for Elevator Controllers (To design and install an elevator for a Class I, Division 1 location would be quite an undertaking.).
