I am planning a new layout and am currently determining the electrical needs including outlets. Does anyone know the maximum amps that a Z4000 transformer draws? I have looked on lne, on the box, and the actual transformer, but don't see that info (perhapsI am just blind as my wife would opine!!). I see how much output it can produce but not how many amps it draws at 110 volts. Thanks in advance for your help. Paul

400 watt @ 110 volts 3.63Amps approximate.
14 volts fixed @ 3 amps 42 watts
10 volts fixed @ 3 amps 30 watts
(2) 180 watt track circuits 360 watts.
Total less duty factors 432 watts less approximately 10% = 389 watts.
Remember that it can't really be 100% efficient, so I'd expect it to draw at least 10% more than it's output power.

I would just say 4 amps, with room to spare. 5 of them on a 20 amp circuit wouldn't be an overload.
True Rob, and that would only be if all of them are loaded 100%, when's the last time that happened! 
Exactly.
Are you saying the Z4000 has the ability to put out 400 watts divided between 4 channels? Or 100 watts per channel max.

From the user's manual. 400 watts total from all outputs.
The Z-4000 was designed to operate any AC-powered model train or operating accessory. The transformer contains two variable outputs, each capable of providing 180 watts to the track or accessory, and two fixed voltage outputs of 10 and 14 volts repectively. The fixed outputs are designed for powering accessories like lamps and switches, while the variable outputs should be utilized for locomotive and operating accessories. In addition, the Z-4000 features individual circuit breakers for each output and utilizes a state-of-the-art design that minimizes voltage fluctuation when bell or horn buttons are activated.

Most of the power is dedicate to the two track circuits. 180 watts each.

Accessory circuits have much smaller capacity.

400 watt @ 110 volts 3.63Amps approximate
Thank you, I have a friend that is looking at the z400 or bricks. He has a couple of TIU's

hello guys and gals.......
Is it more output if the outlet is 115 or 120 volts ?

The outlets in your home will vary in voltage. 110 is a minimum, I've seen voltages as high as 130 volts. My home seems to operate at about 122 volts.
It shouldn't be as it's regulated internally.
