Abstract
An adapter is provided for adapting a voltage or phase rotation indicator for use with multiphase electrical power. The adapter allows the phase rotation indicator to be used in situations where it might not otherwise be used, such as when the power conductors are not contained in a power meter box. The adapter may also be used as a protective carrying or transport cover for the indicator when the indicator is not in use.
Claims17
An adapter for connecting multiphase electrical power conductors with electrical contacts of a phase rotation indicator having a hanger jaw mounting apparatus therewith, the phase rotation indicator including a test circuit to test the phase rotation of the multi-phase power in the power conductors, comprising:
- an insulative plate member;
- terminal means mounted on said plate member for connection to each of the multiphase electrical power conductors;
- electrical contact means on said plate member connected to said terminal means and adapted for engagement with the electrical contacts of the phase rotation indicator;
- means on said plate member comprising a raised lip extending outwardly from said plate member for fitting into the hanger jaw of the mounting apparatus for engaging the mounting apparatus to align said electrical contact means with the electrical connectors of the phase rotation indicator.
