The TR 26 safety transformers are used in supplying spotlights swimming pools, fountains, and other moist location. For safety measures, it is advisable to supply with safety extra low voltage (SELV). Transformers with other rated power or other line lengths between transformers and spotlights are also available upon request.
The transformers (and their lines) must be protected against overloads and short circuits. This protection is also a requirement of the standards and the national regulations about electrical installations.
