Hello AAC Forum,
Thanks to ronv, tkao21203, Sensacell, Colin55, Wendy, ebeowulf17, Dodgydave and others,
whose name I have missed, with DC circuits in the past.
I think that's my problem today. Except the occasional home repair, little experience has been acquired with AC.
The system being constructed is a landscape lighting circuit and it is 12 volts AC not DC. Pretty sure I know the issue but would like to confirm theory and query about an aspect of the solution.
Have wired a harness for the system as shown in plan A.
But the two lights on the east side don't come on. Tried
known good lamps and check for voltage with DMM. Both negative.
I believe the layout that will work is this and am in the process of testing.
I believe that the tee to the east side in plan fouls the path to the east side.
I am not sure, but it is surmised that the pulsing (60 Hz) nature of AC
makes a tee split off not possible. Or that an AC circuit can only pulse
down one main spine and that creating a bifurcation interrupts the
60 Hz alternation.
If that is true there is only one fly in the ointment: the tee configuration
exits at three of the four lights. At the last light the connection is a continuation
of the two connector spines. But on the lights between spine and the last fixture the
tee connection to the fixtures exists.
Perhaps a tee with a short extension will work but a longer, major second spine will not.
So the questions are.
1. Will an AC circuit allow a tee split as shown in plan A?
2. If so why does the tee juncture to the fixtures work?
Thanks.
