What is the requirement for the lighting in the elevator hoistway pit?

The requirement for lighting in the elevator hoistway pit specifies that it shall not be connected to the load side of a ground-fault circuit interrupter (GFCI). This stipulation is based on safety considerations, as GFCIs are designed to protect against electrical shocks by disconnecting electrical circuits when they detect ground faults. However, in the case of elevator hoistway pits, which can have specific environmental and operational conditions, using GFCIs could lead to unwanted tripping during normal elevator operations.

Additionally, maintaining reliable lighting in elevator pits is crucial for safety during maintenance and emergencies. If the lighting were to be interrupted due to a GFCI trip, it could pose significant risks to technicians working in the pit. Therefore, it is designed to not be connected to the GFCI to ensure constant illumination without the risk of nuisance tripping, supporting both safety and operational reliability for elevator systems.

Options suggesting that the lighting can connect to any circuit or should have a dedicated line focus more on flexibility or circuitry details but do not address the specific safety concerns related to ground faults in elevator contexts.
