An electrical connection box. The box comprises a hollow, molded or cast housing having plural walls, at least one of which including an opening configured to receive an electrical conductor therethrough. Tightenable clamping means are disposed adjacent to the opening for clamping the conductor in place. The clamping means includes a contact shoe which is integrally formed with the housing and which is breakable therefrom at a break point when the conductor is to be clamped. The breakage of the shoe from the housing enables the shoe to be brought into clamping engagement with the conductor. In one embodiment of the invention the clamping means is mounted inside the box. In another embodiment the clamping means is mounted outside the box. The openings for the conductor can be configured for either ROMEX or BX type cables. Breakaway mounting flanges are provided on the box.
An electrical connection box comprising a hollow, integrally formed housing having at least one wall, said wall including an opening therein configured to receive an electrical conductor therethrough and into the interior of the box and tightenable clamping means disposed adjacent to said opening for clamping said conductor in place, said clamping means including a contact shoe integrally formed with said housing and being breakable therefrom at a break point when said conductor is to be clamped to enable the shoe to be brought into clamping engagement with said conductor upon the tightening of said clamping means.
