I do a lot of dedicated lines for landscape lighting for another company. We have been having problems with inrush tripping breakers.
We have used 1200 watt trans from multiple manufactures but have had trouble anyway. Breaker style or manufacture doesn't seem to matter, although SqD work best.
On the last project that was on a pool panel where the line was 5' long I buried a 50' run of 12/2 UF under ground to provide a cushion and it works well. Anybody have similar problems or solutions besides extending the run?
