An electrical junction box for swimming pool light fixtures includes a metallic base plate and a polymer cover member. the base plate includes lower conduit hubs in a circular array, and a dual-function strain-relief and ground wire connecting structure adjacent each electrical wire opening on the upper side of the base plate. The strain relief structure are arranged to centralize the wires brought into the junction box, while the ground wire connecting structure (and a bonding wire features as well) provides unprecedented convenience of termination from the centralized wire connections. The strain relief, ground wire, and bonding wire features (as well as cover member installation on the base plate) allows their use without need to horizonal access to the junction box, access, vertically downward from above is all that is needed. Also, the junction box is of circular plan form with features circularly arranged to provide multiple axes of symmetry in plan view, approaching a rotational symmetry, and allowing an omnipositional use of the junction box with respect to its rotational position in plan view. As a result, conduit risers at construction sites may be merely bunched at the location where the junction box is to be installed.
