Like other DIY's on this forum I had to learn first by making mistakes. So now I'm here, looking for advice. I am attempting to install 5 50w (250w total) uplights that line my driveway. The transformer , was a 300watt home depot model, but I now purchased a 300w kichler professional series multi tap , which is located 167 feet from the last fixture. Here are some possible solutions to fix my 12/2 awg initial install that resulted in severe voltage drop. 1) Keep the transformer where it is (easiest) and use 2 runs of 10 ga wire 1 to the last 2 trees and another to the first 3 trees. 2) 12/2 awg to the first 2 trees, 10/2 awg to the 3rd and 4th trees, and 10/2 single run of 167 ft to the 5th tree. 3) Use an underground transformer and install underground line voltage in the middle of the project and simply use 2 runs of 65 ft 12/2 to supply all fixtures. (obviously the most costly and time consuming) Would one of the first two options work? Anyone have this situation and know how to remedy it? I have a voltmeter, what is the ideal voltage at the fixture? 11v? 11.5? and I know this is a really dunb question, but where exactly do you measure the voltage? before the fixture? after it? right at the bulb? [/I]Thanks for any input.
