Re: Outdoor wiring
Walt I know of LV systems that have been in for nearly 20 years with little or no problems and system that were replaced after 2 years. I think it is going to depend on the system you get a $3 system from Borg isn't going to hold up but a high end system will. The main thing is to get a good system, do the installation as instructed by the manufacturer and don't shortcut the waterproofing. The lower the voltage the bigger the wires for a given distance to reduce resistance. Dropping 5 volts on a 120 volt system is no big thing but dropping 5 volts on a 12 volt system can be a big problem. By the way I like soldered connections on LV circuits.
