Lightbulb 15 Volts enough ?

How many Contractors use Transformers with more than 15 volts? Do you find you need to go more than 250 feet most of the time? Do you seek a Transformer with 17,18,22 volts? What are people using? Thanks

I have never used one, but I did bid a job the other day with a run of probably 80 yards. I would imagine with even I would have to use one huh? Dont' know really didn't figure it up, but I could see in certain cituations where you would have too.

Our goal is to always use the lowest possible voltage tap – the higher the tap, the more energy cost is lost with voltage loss in the wire.

Having said that, (4) 35w lamps at 175 ft. using #10/2 wire requires the 16 volt tap.

Techniques (some obvious) to keep voltage loss to a minimum:

1. Reduce wire run lengths by positioning transformers closer to the fixtures. For example, instead of running the whole job from a single transformer at the house, use additional transformers positioned at strategic locations.

2. Use heavier wire gauge or even double up on wires.

3. Use more wire runs with lower loads on each run.

Most installers rarely need to use 18v taps and above.
