A New Old Project Started for Ballast Cables
2007-01-26

At its meeting on Friday morning, 19 January 2007, the Electrical Power Working Group voted to start the process of reaffirming ANSI E1.16 - 2002, Entertainment Technology – Configuration Standard for Metal-Halide Ballast Power Cables. The document describes a standardized grounding contact assignment for detachable power cables on 6kW, 12kW and 18kW metal-halide lamp ballasts for portable studio luminaires that use the MIL-C-5015 connector with #28-6 insert configuration on the ballast end of the power cable. In a nutshell, it says that contact A shall be used for the protective grounding contact. This advice, if followed, avoids the problems that can result when a power cord that uses A for power is plugged into a ballast that uses A for ground. (It's been done.) The standard is available on the ESTA website for free at http://www.esta.org/tsp/documents/published_docs.php.

No changes are planned at this time for the document, but the reaffirmation is a project, and ANSI requires that the start of any project be announced so that parties who might be affected can comment or become involved if they wish. Therefore, any parties who would be materially affected by the reaffirmation of this standard (e.g., luminaire and ballast manufacturers, users, and lighting rental houses) are invited to join the Electrical Power Working Group to work on the reaffirmation of this standard. Information about joining working groups and a link to the working group membership application form are available at http://www.esta.org/tsp/working_groups/index.html. Also, any parties who wish to comment on this reaffirmation or to object to the reaffirmation of this standard, because it is unnecessary or because it conflicts with another American National Standard, are invited to send their comments or objections in writing to the Technical Standards Manager at mailto:standards@esta.org. The deadline for comments is 11 March 2007.
