Inductive power couplings for pool and spa equipment

A cable swivel for inductive power couplings for powering pool or spa components is provided. A swivel component allows a power cable to a pool or spa component, such as an electric pool cleaner, to swivel when the inductive power couplings are coupled together. The couplings include a first inductive coupling that can be positioned within and/or mounted into a wall fitting, a second inductive coupling that inductively couples with the first inductive coupling, and a swivel component attached to the second inductive coupling for allowing the second coupling to swivel with respect to the first inductive coupling. A retainer ring engages with the wall fitting and retains the first and second couplings and the swivel component in position within the wall fitting.
