I got a 600W Malibu low voltage transformer powering my landscapelights. But some of the lights further from the transformer are not asbright. I only have a single 12 gauge wire with all the lightsattached on it.Can I attach another 300W transformer at the far end of the wire sothat the lights there will be brighter?I cannot really run another wire from the 600W transformer, since muchof the wire run under concrete pathways and also my driveway.Thanks

Cut the existing wire in between two lights, so 1/2 of the lightsremain attached to the 600 watt transformer. Properly seal the cutends so they don't touch and are protected from moisture. You coulduse 4 sealed direct burial wire nuts, for example. Then connect thenew transformer to the far end to power the other 1/2 of the lights.Size the new transformer properly to handle the lights it is powering.It may not be 300 watts, as all the lights may not be the samewattage. Make sure you use heavy enough wire, and if you have a longrun from the transformer (say 50 feet or more) get a transformer withtaps so you can start with a slightly higher voltage to compensate forloss in the long wire. The better low voltage transformers haveseveral taps for this purpose.You can do this without cutting the wire if you get the phasingcorrect, but if you separate into two groups, you eliminate any chanceof confusion now and in the future.HTH,Paul F.

2 low voltage transformers on 1 circuit?

But it would emerge (at the secondary) as (sorta) AC, strangely enough. So it is essentially AC (a degenerate case, only half the wave). Real DC cannot "go through" a transformer.

AC should do this is wall as DC, it's just the phase (rather than polarity) you have to pay attention to. I know I have seen circuits with multiple AC sources connected together.

"is wall as DC". Please explain.Why does a wall enter this conversation?
