1.3.1 Applications. This Standard applies to the installation of all powered phitiorms and traveling ladders and gantries.
1.3.2 Deviations. Deviations from the requirements of this Standard may be granted by the enforcing authority it it is determined that a specific requirement creates practical difficulty or excessive hardship, or where the specific requirement prevents the use of a novel design, only when equivalent safety is provided.
1.3.3 Alterations
(a) Any existing building being serviced may continue to be serviced until the building is altered, requiring a modification of the installation. Alteration of the building and equipment modification shall then he made to comply with the applicable parts of this Standard.
(b) lithe authority having jurisdiction believes that hazards exist to warrant a change in an existing installation, the authority may require compliance with any part of this Standard. If a qualified person deems that a hazard exists, the hazard shall be corrected, and the correction shall be in compliance with this Standard.
(C) Once a building permit is issued or modified, the current version of the Standard shall apply.
1.4 References
When a nationally recognized standard, other than that specifically referred to in para 1.1, is referred to and is superseded by a revision, the edition current at the time of acceptance of this Standard shall apply.

2.3.6 Electrical Requirements. The electrical design shall be in accordance with the following:
(a) General design shall be in accordance with the applicable requirements of the National Electrical Code edition in effect at the time of making the design, e.g., grounding, wire sizes, motors, controls and control wiring, and enclosures.
(b) When full load is applied to the circuit, building conductors shall be of such capacity that not more than a 3% voltage drop from nominal equipment requirements shall occur at each building outlet.
(C) Communications and power connections shall be weatherproof and provided with locking type connectors. They shall be protected from damage and abrasion.
(d) Each communication and power outlet shall be provided with an adjacent strain relief anchor to prevent force from being applied to the outlet or to the conduit leading to the outlet by movement of the equipment.
(e) The equipment power supply shall be from an independent electrical circuit that shall remain separate from all other equipment within or on the building, except hand tools used in conjunction with the equipment. If the building is provided with an emergency power system, the equipment circuit may be designed so it may be connected to the emergency circuit.
(f) The power circuit shall be provided with a cutoff switch that can be locked in the “OFF” position. To allow the equipment operators access to the switch, it shall be conveniently located relative to the primary operating area of the equipment.
(g) Power and communication outlets shall be located at the approximate elevation of the primary equipment operating area. The outlets should be located so that no more than 100 ft (30.38 m) of supply cable need be used for the horizontal area being traversed.
(h) The power circuit shall contain a separate equipment electrical grounding conductor.
(i) Carriage track systems shall be electrically connected to an earth ground.
(j) Communication Facilities. A two-way voice communication system shall be provided between the equipment operators and a manned station while the working platform is in use. The communication facility shall be operable and manned at all times when the equipment is being used.
