A traditional elevator installation (which includes a machine room) requires access inside the elevator shaft. Where the elevator shaft and/or equipment room has a sprinkler fire suppression system installed, the elevator Code requires main line power to the elevator be removed prior to the application of water. 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. In order to aid enforcement, the panel additionally required marking the available fault current at the elevator controller. The standard for Elevator and Escalator Electrical Equipment is the ASME A17.5-2014. Part IX, Grounding, states that metal raceways, Type MC cable, Type MI cable or Type AC cable attached to elevator cars are to be bonded to metal parts of the car bonded to the equipment grounding conductor. NEC Article 620 Part VI, Disconnecting Means and Control, is rather exacting. The conductors must be in their original sheaths or grouped together and taped or corded. Luminaires must be lensed or equipped with wire guards to protect the lamps. The simplest option is to use a shunt trip circuit breaker in either the feeder supplying the elevator or the elevator disconnect. Each fused switch or circuit breaker in the panelboard is used as an elevator disconnect. Any hoistway not meeting those requirements must have an upright, pendent, or sidewall spray sprinkler installed at the top. Thus, the traveling cable must be supported by a steel supporting member.
