Frequently Asked Questions (FAQs)

1. Can low voltage transformers be mounted outdoors?

Yes, low voltage transformers can be mounted outdoors. They are specifically designed for outdoor use, making them ideal for outdoor landscape lighting. These transformers are durable and do not require frequent maintenance, allowing for reliable operation in various weather conditions.

2. Which transformer is used for outdoor?

For outdoor use, Pad Mounted Oil Filled transformers are commonly used. They are rated to withstand outdoor conditions for decades. However, if you need a transformer for voltage conversion, such as from 480 to 208 volts, a dry type transformer may be suitable.

3. Do I have to have a transformer for low voltage landscape lights?

Yes, a transformer is necessary for low voltage landscape lights. It is required to reduce the 120-volt output from your home electrical system to the 12 volts used by low voltage landscape lights. This allows for safe and efficient operation of the lights.

4. How do you protect a transformer outside?

To protect a transformer installed outdoors, it is recommended to follow the guidelines provided by NFPA 850. This may include using a fire wall rated for 2 hours, extended vertically and horizontally. Specific protection measures may vary depending on the size and type of the transformer.

5. How do I hide a transformer in my yard?

There are several ways to hide a transformer in your yard. You can cover it up with grasses, plant evergreen shrubs around it, create a screen using a decorative fence, or use a fake boulder to conceal it. These methods can help blend the transformer with the surrounding landscape.

6. How many lights can you put on a low voltage transformer?

The number of lights that can be connected to a low voltage transformer depends on its maximum capacity. As a general rule, the total load on the transformer should not exceed 80% of its maximum capacity. For example, a 150 watt transformer can comfortably handle up to 120 watts of power, which would typically allow for around 6, 20 watt lamps.

7. How do I choose a low voltage transformer?

To choose a low voltage transformer, compare the total wattage of your lamps to the available transformer sizes. Transformers typically come in sizes like 300W, 600W, 900W, and 1200W. As per electrical code requirements, transformers should be derated to 80% of their capacities. For example, if you have a total lamp wattage of 600 watts, you would need a 900-watt transformer (600 x 0.8).

8. Do I need a special transformer for LED landscape lights?

Yes, if you are installing low voltage or 12-volt LED landscape lights, you will need a special transformer. LED lights have specific voltage and current requirements, and a transformer designed for LED landscape lights ensures proper operation and longevity of the lights.
