[quote]QUOTE: <i>Originally posted by jfugate</i> <br /><br />Yep, it depends on the size of the layout. <br /> <br />Trainnut gives the basic rule of thumb 100 watts = 1 amp. <br />....I expect at most there will be up to 4 trains in motion at a time on the layout, with a couple more yard switchers in operation. Each train could have 4-5 locos in it (head end + helpers). I model the 1980s so we're talking diesel locos here. Modern low-amp diesels normally take about .25 amps each, so 22 locos would total up to about 5.5 amps ... plenty of room to spare on the 15 amp circuit.[/quote] <br /> <br />Remember Joe: <br />It's wattage that is usually the goverering factor: your 5.5 amps is at 14 volts which is 77 watts, while the 15 amp circit breaker is at 120 volts which is 1800 watts. The supply is a lot greater then the demand. <br /> <br />In my train room I have a light switch at the door that controls several recepticales and the layout is plugged into them, so when I leave the room and turn off the lights I can turn off the layout at the same time. <br /> <br />Have a good day <br />Bob
