Hello All, I'm trying to build a staging yard for rolling stock. The yard will have 7- lionel 022 switches. I'm using an American Flyer 30B transformer. Each staging track is isolated to be powered independently. I used 14 awg wire for track power. I ran 22awg 4 conductor security wire from the remotes to the switches. Each remote wiring assembly is approx 12 feet long. Tried powering the switches with this but with 20 volts from the transformer i only get 12 volts at the switch. Each switch is pulling about 0.37 amps. I'm guessing the 22 awg wire isn't big enough. What would be the best way to power the 7-022 switches?

I have been using 18/7 thermostat wire for my switches and accessories, including power to my yard with 6 O22 switches. My longest run is only 8 feet though, and operation has been snappy with 14V on the ZW dial (haven't measured the voltage at the switch).
Try doubling up the 22ga phone wire and see how that works. Measure the voltage to see how much it changes. It may be the simplest way forward for you. Switches only use power for a very short period of time. Most of the time they just sit there idle.
Aux power to 022 switches should be 18 awg wire for best results. Still, I can't believe you are losing 8 volts in a 12 ft run running only the lights. How long is your wiring to the controllers? That length must also be considered. You may also want to consider changing the bulbs over to led replacements. As long as you are powering them with ac the leds will work fine.
