1. A power supply for powering pool or spa equipment, comprising:

  • a power supply unit external to a pool or a spa;

    a first inductive power coupling including an inductor circuit, said first inductive power coupling in electrical communication with the power supply unit and at least partially embedded in the pool or spa;

    a second inductive power coupling including an inductor circuit, said second inductive power coupling received by said first inductive power coupling in the pool or spa, wherein the inductor circuit of the first power coupling inductively transmits power from the power supply to the inductor circuit of the second inductive power coupling for powering a device in a pool or spa connected to the second inductive power coupling; and

    a cable connected at a first end to the device and at a second end to the second inductive power coupling such that the second inductive power coupling is detached from the device, the cable delivering electrical power to the device and permitting movement of the device relative to said first and second inductive power couplings while said second inductive power coupling is received by said first inductive power coupling.
