Doing some landscape lighting.. I energized the fixtures I had installed to see if the blue tooth fixture were going to work... so, I have 6 homeruns coming back. I pig-tailed them to fit under the lugs of the transformer.
I have the transformer plugged in and turn on the switch on the transformer which is also over-current protection.
There's a buzz from the transformer, the lights are on for about 4 or 5 seconds and the OC trips off. (great).
I turn the switch on again, no buzz but in about 5 seconds it trips....
(I may have tried one more time)
I get my amprobe, clamp around the pigtail turn it on and the amperage is climbing up to 35 amps.... I turn it off.
There are only 12 led's on the circuits currently ... 6 maybe 8 amps the most (if that).. I break the pig tail apart and feed each circuit going out one at a time, check amperage and repeat thru the circuits (each separately). I get thru 3 ok... I wire the 4th, turn it on and it starts climbing to 28 and going. I turn the transformer off (Thinking ok, at least I know where to look). Try turning the transformer back on and it starts raising again... up to 25 and then before I turn it off it starts dropping by itself... down to a few amps that it should be..and the transformer and couple lights stay on.
So I have literally two blu tooth fixtures on the circ., and a regular area light with no bulb in it...I checked the wiring,all looks good (didn't bulb the area light yet.. will tomorrow) blu tooth fixtures work..
I will check wiring and put that bulb in tomorrow to check...
I rehooked up the other circuits to the pigtails, turned the transformer on and all worked the way it was supposed to.
questions..
Does 12v have the capability to blow or burn a short and clear itself?
Would a blu tooth fixture short clear itself and still work?
And my biggest question... did I damage the transformer? Or, are they built to handle that load till the internal OC trips?? (300 watt 120/12 xformer)..
Thank you
