Transformers with Digital Timer
Cal Pump transformers reduce 120 volt to a safe, economical 12 volt power supply for many low voltage applications, with the added convience of programmable digital timers. These transformers eliminate the risk of electrical shock to children and animals if the cable is accidentally damaged or cut. The TRT75 and TRT150 transformers are ideal for powering all of your low voltage lighting.

“680.23 Underwater Luminaires.
This section covers all luminaires installed below the normal water level of the pool.
(A) General.
(1) Luminaire Design, Normal Operation. The design of an underwater luminaire supplied from a branch circuit either directly or by way of a transformer meeting the requirements of this section shall be such that, where the luminaire is properly installed without a ground-fault circuit interrupter, there is no shock hazard with any likely combination of fault conditions during normal use (not relamping).
(2) Transformers. Transformers used for the supply of underwater luminaires, together with the transformer enclosure, shall be listed as a swimming pool and spa transformer. The transformer shall be an isolated winding type with an ungrounded secondary that has a grounded metal barrier between the primary and secondary windings.”
