It takes 120V in and offers 12, 13 and 14 volt taps out, in a beige steel enclosure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it is for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTransformers of this type are specifically designed to supply 12 volts to pool and spa lights, submersible fixtures and outdoor garden lights. The safety construction is what separates them from a general purpose transformer: a grounded shield sits between the primary and secondary windings to assure safe operation, and built in circuit protection disconnects power to the transformer if a defect or an overload occurs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoosing the tap\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe three output voltages exist because cable runs lose voltage. A short run to a single fixture is happy on the 12 volt tap. A long run, or several fixtures on one circuit, may arrive dim on 12 volts and read correctly when moved up to 13 or 14.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSizing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTotal the wattage of everything on the circuit and stay under the transformer rating.
