Hazard boundary termination box
A termination box, for maintaining an electrical connection across a boundary, can include a terminal block comprising a heat-resistant, non-conducive material having a first surface and a second surface. The first surface can include electrical terminals thereon connected to electrically conductive linkages passing through the terminal block and connecting to electrical terminals on the second surface of the terminal block. The termination box can also include a first cover and a second cover each having a cable conduit passing therethrough for receiving an electrical cable from the respective side of the boundary.
