1. An electrical assembly for grounding an elevator assembly, the elevator assembly having an elevator cab, a grounded fixed member, at least one sheave, and at least one suspension member having one or more conductive members and a sleeve enclosing the one or more conductive members, the at least one suspension member extending around the at least one sheave to support the elevator cab, the electrical assembly comprising:
a bracket coupled to the grounded fixed member;
a grounding member coupled to the bracket, wherein the grounding member is electrically coupled to the at least one sheave such that contact with the at least one sheave forms an electrical ground path between the at least one sheave through the grounding member and the bracket, and into the grounded fixed member such that when the at least one sheave moves the at least one suspension member, any portion of the one or more conductive members from the at least one suspension member making contact with the at least one sheave grounds the at least one sheave to the grounded fixed member via the electrical ground path; and
a monitoring system having at least one sensor and a controller, the at least one sensor is coupled to the one or more conductive members to send and detect a voltage through the one or more conductive members, the controller monitors the voltage sent and detected through the one or more conductive members by the at least one sensor to detect when the electrical ground path is formed between the one or more conductive members and the grounded fixed member.
