Junction boxes for enclosing and making electrical connections to LED drivers are disclosed. The junction boxes include a bottom or base and a cover. Dividers arising from the base divide the junction box into high-voltage and low-voltage compartments. A cut-out open at the top of each divider allows a driver to be placed in a junction box without having to pull wires through holes or openings. Typically, the base is open along the top and along at least a portion of one sidewall, with the cover being L- or U-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes. Embodiments that can house several drivers or components within one junction box are disclosed, as are weather- and water-resistant embodiments.
