NFPA 70: National Electrical Code With this comes deteriorating service and significantly higher phone line costs. <> This means that the majority of hydraulic type elevators will require this and traction type elevators need it only where the construction of the shaft is of combustible or limited-combustible material. Traditionally, the electrical system design engineer has given little attention to the elevator controller. The Safety Code for Existing Elevators and Escalators is the ASME A17.3-2015. 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)]. SPECIAL CONSTRUCTION. Passenger elevators: Like Section 3007.8, Section 3008.8 requires the features of an occupant elevator to receive power from the normal and standby power supplies. They are permitted to be run without raceway when used inside the hoistway, on the elevator car, hoistway wall, counterweight, or controllers and machinery located inside the hoistway, provided they are in their original sheaths. The traveling cable, moreover, may be run without raceway from inside the hoistway to elevator-controller enclosures and to the elevator car and machine room and similar locations outside the hoistway for a distance not exceeding 6 ft. For instance, one method to reduce the available fault current is to add an isolation transformer ahead of the elevator controller. x5s, rh Ds(6Fh.GF#m G&;w @H5xw"` d @ t?G,`@Cl( {@ ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. The same figure applies to nonmetallic wireways. For instance, a typical elevator controller may traditionally have SCCR ratings from 5 to 10 kA. The basic idea is that there must be a separate, dedicated circuit for car lights, receptacles and ventilation on each car. NEC Article 620 contains numerous other disconnect provisions, which must be carefully scrutinized prior to design work so the installation is compliant. You must locate this key switch at the main lobby or at the building fire command center. If your specifications require a vent at the top of the shaft for venting smoke, you must provide a key switch with a pilot light to control that vent. High-rise buildings pose additional concerns. The locking capability is important so during maintenance, the equipment will not be inadvertently energized. Equipment covered in Section 1.1.2 of the ASME A17.1 Safety Code for Elevators and Escalators. Elevators with driving machines located on the car or counterweight, or in the hoistway are permitted outside the specified spaces. In addition, requirements for selective coordination and shunt tripping should be complied with as needed for the installation. Here again, the lighting is not to be connected to a GFCI, whereas such protection is required for the receptacle(s). So, we see that for elevator work, greater fill is allowed. Other Consideration Fireman telephone jacks and telephone cabling are typically sufficient for each of these locations. 13 0 obj Here is the current code where (a) was added to limit the NEMA Type 4 to elevator electrical only. 10 0 obj xc`? <> stream NEC Article 620 Part V, Traveling Cables, is driven by two major issues.

It can seem such a tedious process, especially since elevator code falls under many different bodies. These include the installation being in accordance with NFPA 101, Life Safety Code or the applicable building code as well as the space being dedicated to elevator equipment only, protection by smoke detectors or other automatic fire detection, separation from the rest of the building by construction with fire ratings specified by the applicable building code, and no materials unrelated to elevator equipment being stored in the space. These are the individual branch circuits required for car lighting, receptacles, auxiliary lighting and ventilation on each elevator car; individual branch circuits for machine-room and similar location lighting and receptacle; and branch circuits for hoistway pit lighting and receptacle(s). There are many fire and life safety code provisions that mitigate this risk and permit elevators to be used without increasing the risk to occupants. Elevator Electrical Requirements By General Contractor/Owner Each residential elevator requires three (3) items from your electrician and telecommunications contractor(s). It is of great importance for the design engineer to communicate with their local authority having jurisdiction (AHJ) to determine fire alarm requirements for the respective elevator installation. x g*P1S0@ _j !wU!5corVIaVC.|<= GFCIs in Elevator Pits, Receptacles and More - Electrical Contractor 354 Morgan Ave. You can email the site owner to let them know you were blocked.

Cloudflare Ray ID: 7c0a60ef2d0d43c2 Similar provisions are attached to elevator-car heating and air-conditioning disconnecting means, and to other utilization equipment. The ASME A17.1-2016 is for new and altered installations. Kings III makes it easy as a single point-of-contact for all your emergency response needs. endobj This device must be either a fused disconnect or a circuit breaker because ANSI/ASME A17.1 requires you to install an additional overcurrent protection device (OCPD) in the elevator equipment room. 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. The elevator shall be accessed from either an . A further requirement concerns elevator-car air-conditioning and heating. Another location that requires a separate branch circuit for lighting and receptacle(s) is the hoistway pit. endobj <> stream Corporate Office The International Building Code is updated every year. A traditional elevator installation (which includes a machine room) requires access inside the elevator shaft. The elevator equipment room that serves a hydraulic elevator is almost always located on the lowest floor adjacent to the elevator shaft. Another important electrical system design consideration for supplying power to multiple elevators is NEC 620.62. Chapter 27 Electrical. Elevator Machine Room, Machinery Space, Control room, Control space Since 1953, Elevator World, Inc. has been the premier publisher for the global vertical transportation industry. 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. Main feeders that supply elevator power must be kept outside the hoistway unless one of the following applies: Feeders for elevators are permitted within an existing hoistway (provided they are not spliced within the hoistway) by special permission of the AHJ. 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. %PDF-1.4 [emailprotected] "- L_bM xmZ@1sH6A=D"A i(/B(] {o 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.
