Abstract
A combination panelboard-switchboard housing accepts plug-on connection with a plurality of electric switch-circuit breaker modules. Circuit breakers can also be directly connected into the bus bars in a plug-on connection with minor modification. The bus bars are "edge-mounted" such that the minor dimension of the bus bars is perpendicular to the bottom of the housing to receive the modules as well as the circuit breakers, per se. Plastic or fiber insulation shields are arranged over those bus bars that are not connected with the circuit breakers or modules to prevent inadvertent contact with the bus bars when energized.
Claims10
An interior for an electric switch or circuit breaker enclosure comprising:
- support means supporting a plurality of electric switches or circuit breakers;
- a plurality of electric bus bars extending along said support means and arranged for connecting with said electric switches or circuit breakers;
- a pair of support rails arranged at opposing ends of said support means, said support rails including a plurality of slots through said support rails;
- and
- an electrically insulating shield removeable attaching between said support rails and arranged over said bus bars thereby preventing access to said bus bars.
An electrically-insulating bus bar shield comprising:
- a sheet of plastic or fiber material having a pair of opposing ends;
- at least one tab extending from each of said opposing ends providing means for removably attaching to a panelboard or switchboard interior;
- and
- at least one aperture formed proximate said ends providing manual engagement means for ease in attaching and removing said shield from the interior.
