System for building an electrical device into a conduit shallower than the device

摘要

A system for building at least one electrical device into a wiring conduit whose depth is less than the depth of the device includes at least one support which can be fixed in the conduit and receives the electrical device(s) so that a front face of the device or each device is flush with a front face of the conduit via an opening formed in corresponding relationship therein. The system further includes at least one pattress which is passed through an opening formed in corresponding relationship to it in the bottom of the conduit to form therein a recess for accommodating a rear part of the device. The pattress is separate from the support and has its own means for fixing it to the conduit.
