N.E.C. (National Electric Code) - As It Relates to Low Voltage Lighting

[The Lighting Geek]

I also remember hearing that the smaller fixture wire has to be trimmed to 12" of the connection of 12 gauge, in situations where there is no hub. That along with the talk done by Naomi was awesome and enlightening. Sure glad I was there.

good info.

The 12g wire is news to me. we use it for main runs, use fixtures with 25 foot 16g leads, but we still use quite a bit of halogen too and need the 12g. I thought one of the money saving issues with LED was being able to use the lighter guage wire. If this is the case, perhaps trans will be coming along with smaller zones or commons and have smaller amp breakers to allow the use of 16. but I am pretty sure you can trip a 25a breaker on 16g. wire. easy to test. I will try that tomorrow.

I rarely find systems installed to 6", the only times is usually the lighting was wired the same time as irrigation installed and a trencher was used. we do 4-6"

sadly, the telephone, invisible dog fence and cable companies rarely bury their wires much more than 1-2". I know. I hit them all the time.
