- The conductors supplying the other two phases of the power supply are insulated.
- The power for all phases is obtained from an insulating transformer.
- The voltage does not exceed 300 volts.
- The rail serving as a conductor shall be bonded to the equipment grounding conductor at the transformer and also shall be permitted to be grounded by the fittings used for the suspension or attachment of the rail to a building or structure.
