Ok guys so I'm lost on the most efficient way to wire this design and some math on voltage drop. 1. the client wants the front yard, walk and driveway lit from sunset to midnight everynight. But they want the ability to flip a switch and keep the lights on longer as they often entertain late on weekends in the summer. How can I wire this so that way the timer will shut off at midnight but the client can turn flip a swith to leave it on longer? I am thinking to just try to get them to go all LED and leave the lights on from sunset to sunrise. This will solve the issue of needing to turn it on later. But is their another method any of you guys can think of? 2. The client does not want the lights in the back yard on all of the time as they have a large back yard and we will be installing a lot of lights. Again due to the amount of lights I will be leaning towards LED. They want to have a lot of lights for when they entertain on the patio but also want to be able to shut them down for a more intimate and private backyard when they are not entertaining. One thing I am thinking is to run this off of a seperate transformer and have a switched outlet installed. The lights that would be on every night will be powered by the same transformer as the front yard, and the second "switched" transformer would power these other lights. The client also asked about being able to control seperate zones of lights depending on what they would like to light. For example a switch for patio retaining wall lights, switch for the tree mounted down lights, switch for the lights around the hot tub, switch for the rest of the plantings, etc... For this I am thinking to install a switch along each run. What should I consider for voltage drop at the switch? Is the switch even a factor? Can the switch be mounted on the common instead of the powered line, would this not effect voltage drop? Any ideas you guys may have would be great.
