ELECTRICAL SAFETY CODE'

Part 1-Application and Definitions.

Section I. Application.

New Construction.

Order 1000. This code shall apply as a minimum requirement to all new construction and replacements which are begun subsequent to July 1, 1917.

Order 1001. Additions to Existing Lines and Equipment. All work on existing lines and equipment required by this code, which can be accomplished by the addition of new material without the abandonment of the existing equipment and material shall be completed by May 1, 1918.

Order 1002. Replacement of Existing Lines and Equipment. Where the condition of the existing lines and equipment is such that compliance with this code requires their abandonment and the construction of a new system, the work shall be prosecuted as rapidly as the circumstances permit.

Section 2. Definitions.

Order 1010. Meaning of Terms, In this code:

Alive or live means electrically connected to a source of potential difference, or electrically charged so as to have a potential different from that of the earth. The term "live" is sometimes used in place of the term "current-carrying," where the intent is clear, to avoid repetitions of the longer term.

Authorized or qualified means properly qualified or authorized to perform specified duties under the conditions existing. Responsibility for the authorization and decision as to the qualifications of employes rests with the employer or his agent.

Conflicting or in conflict (as applied to a pole line) means that the line is so situated with respect to a second line (except at crossings) that the overturning of the first line will result in contact between its poles or conductors and the conductors of the second line, assuming that no conductors are broken in either line. Provided, however, that lines on opposite sides of a highway, street or alley are not considered as conflicting if separated by a distance not less than 60% of the height of the taller pole line. but in no case less than 20 feet..

Current-carrying part means a part intended to be connected in an electric circuit to a source of voltage. Noncurrent-carrying parts are those not intended to be so connected.

Disconnector means a switch which is intended to open a circuit only after the load has been thrown off by some other means.

Manual switches designed for opening loaded circuits are usually installed in circuit with disconnectors to provide a safe means for opening the circuit under load.

1 This code has been adopted by the Railroad Commission as well as the Industrial Commission.
