Landscape Lighting Problem


Situation: I have a low voltage transformer, output 12V, 200W in my basement. I have a 12 gauge wire running from that to outside of the house, and then another 12 gauge wire connected to that. From that wire I am drawing 199W over two 50W bulbs, and nine 11W bulbs.

Problem: The lights are no longer working, but the transformer is working fine. The wire at the connector seem to have melted parts of the connector, and the wire themselves have each become brittle and hard for about 4 inches on each side.

Question: Is my problem with my size wire gauge, an inferior connector, or the amount of watts I'm drawing?

It could be a combination.

Landscape Lighting Problem


You did not state the age of your installation, or the length of wire runs. These could also be factors. What brand of fixtures do you have?

My understanding of landscape lights leads me to believe that 12G wire can likely handle 200watts of power.

Connectors are a major source of problems over time. What kind did you use. I solder all connections, then encase each with wire nuts/silicone, then wrap in plumber tape. Water WILL get in, and it will damage your wire and connections.

50watt lamps are relatively high. Is the wire damage to the 12G or to the wires leading to the fixtures? Is this the size of lamp that came with the fixture? Is it possible that you have too high powered lamp for this fixture/wire/connector?

You have a recipe for disaster here. EVERYTHING is maxed out. Call your local lighting professional before you have an electrical fire. BTW, what's your voltage at the fixture?
