Using bus bars for lighting houses and street lamps

S L O W L Y  i'am converting all of my INCANs for LEDs in the house and around the layout.

Every time I make a huge switch for LEDS my electric bill lowers.

Wire size has to do with amps. Just a guess, but I would think that #14 is good for the transformer and probably #18 to the bulb loads.

#22 is good to the bulbs. MTH buildings I have seen have 18v bulbs in them.  I convert them to LED lighting. I use a common return bus. I dont use walwarts,instead I use buck converters.

Some of my techniques are shown here with some photos.

#14 wire will carry about 1800 watts. That's a lot of buildings. I have my whole layout on less than that. I think you're over sized on wire and over voltage on leds, unless you are using the strips. Try to get a wattage for the incandescents and go from there.

As an alternative to using a busbar, a length of HO or N gauge track will serve the same purpose. Two conductors, insulated, and easy to mount.

I bought the bus bars.  So tonight I got 90% installed. Worked well.  Used 14 guage wire and had no heat issues. Nothing popped!  Lol.  It is a 120 volt transformer. So there is plenty of room.  About 4 small brownstone townhouses to light.  

 

Then I am waiting for the wall warts to arrive.  So the led lights will have to wait until then.
