Frequently Asked Questions (FAQs)

1. Can low voltage transformers be mounted indoors?

◗ All power supplies are indoor and outdoor rated, but we recommend that the transformer be mounted outdoors. If mounted indoors, then codes should be followed that apply to indoor wiring - especially for wires that pass through exterior walls.

2. Do you need a transformer for low voltage lighting?

Resources. When operating low voltage lights, you need a transformer to convert your standard line voltage (120V or 277V) into low voltage (12V or 24V). This allows your lights to function properly. If you connect low voltage lights directly to line power, the higher voltage would cause them to burn out immediately.
