2.8.2 Electrical Equipment and Wiring

Installation of electrical equipment and wiring shall conform to NFPA 70 or CSA C22.1, whichever is applicable (see Part 9).

Only such electrical wiring, raceways, cables, coaxial wiring, and antennas used directly in connection with the elevator, including wiring for signals; for communication with the car; for lighting, heating, air conditioning, and ventilating the car; for fire-detecting systems; for pit sump pumps; and for heating and lighting the hoistway and/or the machinery space, machine room, control space, or control room shall be permitted to be installed inside the hoistway, machinery space, machine room, control space, or control room.

Bonding conductors from the lightning protection system grounding down conductor to long vertical metal bodies in the hoistway such as elevator rails and vertical wireways shall be permitted to be installed in the hoistway as required by NFPA 780 or CAN/CSA-B72, whichever is applicable (see Part 9). The lightning protection system grounding down conductor shall not be permitted in the hoistway, and the elevator rails shall not be used as the lightning protection system grounding down conductor. Bonding conductors installed in the hoistway shall not interfere with the operation of the elevator.

In jurisdictions enforcing the NBCC or NFPA 72, a means for testing and maintaining fire alarm initiating devices without having to enter the hoistway shall be permitted. When this means is provided, it shall comply with either (a) or (b) below.

(a) The means provided for air sampling shall comply with 2.8.3.1.4.

(b) The means provided by enclosing a fire alarm initiating device within a protective space shall comply with the following:

(1) Hoistway penetration for access panels used for installing, testing, and servicing fire alarm initiating devices shall comply with 2.1.1.1.3.

(2) Access panels shall be rated and listed for the application for which they are installed and shall have a maximum width of 400 mm (16 in.) and maximum height of 400 mm (16 in.). Access panels shall not swing into the hoistway.

(3) Access panel doors shall be self-closing and selflocking. The key shall be Group 2 Security (see Section 8.1).

(4) The space that houses the detection device(s) shall be furnished with protective guards (cages) that will prevent accidental contact by a person or object with moving equipment within the hoistway. No part of the protective guards (cages) shall be removable from outside the hoistway or from within the space between the access panel and the protective guards (cages).

(5) Protective guards (cages) shall separate the rest of the hoistway from the space containing the fire alarm initiating device. The guard (cage) shall be noncombustible openwork material that shall reject a ball 6 mm (0.25 in.) in diameter and be made from material equal to or stronger than 1.110 mm (0.0437 in.) diameter wire. The guard (cage) shall be supported so that when subjected to a force of 450 N (100 lbf) applied over an area 100 mm x 100 mm (4 in. x 4 in.) at any location, the deflection shall not reduce the clearance between the guard (cage) and any elevator equipment in the hoistway below 25 mm (1 in.).

(6) Protective guards (cages) shall be installed so that all required hoistway running clearances and beveling requirements are maintained. In no case shall the protective guards (cages) extend more than 400 mm (16 in.) inside the hoistway.

(7) Prior to installation of fire alarm initiating devices or other fire detection systems in hoistways, layout drawings indicating acceptable installation locations for access panels and protective guards (cages) shall be coordinated with the elevator installer.
