How do I install landscape lighting?

Installing landscape lighting involves running low-voltage wiring from a transformer to LED fixtures, but the 120V connection to power the transformer requires a licensed electrician in Ontario. While homeowners can handle the low-voltage portion, the electrical connection must be done professionally to meet ESA requirements and ensure safety.

The Basic System Components

A typical landscape lighting system consists of a 120V to 12V transformer (usually 300-600 watts), low-voltage LED fixtures, and 12-14 AWG landscape wire. The transformer steps down your home's 120V power to safe 12V for the fixtures. Most systems use LED lights for energy efficiency and longevity - they'll last 15-20 years compared to 1-2 years for halogen bulbs.

The transformer needs to be mounted within 1.5 meters of a GFCI-protected outlet, or hardwired to a dedicated GFCI circuit. In Ottawa's climate, choose a transformer rated for outdoor use with a weatherproof enclosure. Size your transformer by adding up all fixture wattages and adding 20% - for example, ten 5-watt LED fixtures need a 60-watt transformer minimum, but a 75-100 watt unit provides room for expansion.

Installation Process and Limitations

What homeowners can do: Once the transformer is professionally connected, you can install the low-voltage fixtures and wiring. Dig trenches 6-8 inches deep for the low-voltage cable, following manufacturer spacing guidelines (typically 100-150 feet maximum run length). Use direct-burial landscape wire and waterproof wire nuts at connections. Plan your lighting zones - path lights every 6-8 feet, uplighting for trees and features, and downlighting from structures.

What requires a licensed electrician: The 120V connection to power your transformer must be done by an ESA-licensed electrician. This includes installing a new GFCI outlet if one isn't available, or hardwiring the transformer to a dedicated circuit. Any work involving your home's 120V electrical system requires an ESA permit and inspection. Attempting this yourself violates Ontario electrical code and could void your home insurance.

Ottawa-Specific Considerations

In Ottawa's climate, choose fixtures rated for Canadian winters (-30°C minimum). Bury cables below frost line where possible, especially near walkways that get salted. The ESA requires GFCI protection for all outdoor electrical connections, and your electrician will ensure proper grounding and bonding.
