Removable links or removable conductors may be used as the disconnecting means. Other factors that contribute to the practical safeguarding of persons using or likely to come in contact with the equipment. 5 Steps Before Working Lines or Equipment as De-Energized. The dielectric breakdown level is further influenced by relative humidity, temperature, and degree of pollution in the environment. Motor controller enclosures for escalators or moving walks may be located in the balustrade on the side located away from the moving steps or moving treadway. Electricity has long been recognized as a serious workplace hazard. The electric panel door must be able to open to a 90-degree angle.

Application. Each disconnecting means required by this subpart for motors and appliances shall be legibly marked to indicate its purpose, unless located and arranged so the purpose is evident. It designs clearance requirements that make sure employees have enough space around workplace equipment and in work and walking spaces. In order for the 480 volt circuit(s) to be considered deenergized, the lockout and tagging requirements of paragraph 1910.333(b)(2) must be met. While OSHA is only followed in the United States, NFPA is a non-governmental organization. Safety of equipment shall be determined on the basis of the following considerations: Suitability for installation and use in conformity with the provisions of this subpart. Distances shall be measured from the live parts, if they are exposed, or from the enclosure front or opening, if they are enclosed. Other factors which contribute to the practical safeguarding of employees using or likely to come in contact with the equipment.

All panel controls shall be of dead-front construction. Also, from time to time we update our guidance in response to new information. Not posting required clearances in electrical panel areas, generally falls under this type of violation. Means shall be provided at the operating station to open the power circuit to all motors of the crane or monorail hoist where the disconnecting means is not readily accessible from the crane or monorail hoist operating station. 3. Although there were no documented injuries to warrant this change, it's obvious that this requirement should enhance safety. Motor controllers may be located outside the spaces otherwise required by paragraph (c) of this section, provided they are in enclosures with doors or removable panels capable of being locked closed and the disconnecting means is located adjacent to or is an integral part of the motor controller. The safety-related work practices under paragraphs 1910.331 through 1910.335 are predicated on compliance with the aforementioned electrical installation requirements.

If sprinklers are installed in hoistways, machine rooms, or machinery spaces, the disconnecting means may automatically open the power supply to the affected elevators prior to the application of water. This is necessary for all types of work including examination of the electrical panel, making adjustments to the electrical panel, servicing the electrical panel, and of course, performing maintenance on the electrical panel. Electric equipment provided with ventilating openings shall be installed so that walls or other obstructions do not prevent the free circulation of air through the equipment. Services, feeders, and branch circuits. Your question has been restated below for clarity. Reply: An employer who has in his or her workplace contractors or equipment, including a motor control center which are in violation of any of the requirements under paragraphs 1910.303 through 1910.308 are subject to citation based solely on applicable electrical installation requirements. Group 1. Control panels. Clear Height in front of Panel >480V. No fixed work platform has been provided for servicing the unit.

Cord connectors may not be laid on the ground unless listed for wet locations. This means if you have an inspection, you can count on the fact that the OSHA electrical panel clearance will be measured by the OSHA inspector to make sure that you are in compliance. [46 FR 4056, Jan. 16, 1981, as amended at 73 FR 64205, Oct. 29, 2008], Occupational Safety & Health Administration. All splices and joints and the free ends of conductors shall be covered with an insulation equivalent to that of the conductors or with an insulating device designed for the purpose. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. Q: Does OSHA standard 1910.303 include all electrical panels (i.e., electrical cabinets on machinery, electrical disconnects and breaker panels), or is it strictly related to breaker panels? The conductors and equipment required or permitted by this subpart shall be acceptable only if approved, as defined in 1910.399.
