Re: 1156 Bulb Short Protection and Powercab

John Bauchiero <john@...>

I have to agree with Morgan. I do run NCE but the 1156 did not work for me. I use the 1157’s brake filament. One filament of the 1157  is equivalent to the 1156 and the second is a higher current. The 1156 would not light on a short but worse, it would warm up and not pass enough current to the existing locos. I got brave and tried the 1156s in parallel without total satisfaction. So when using the high current 1157 element it worked well and the PowerCab did not trip. It lit on a short but I am not one to leave a short condition for a long time.  I’m a gambler but not to a point to risk my rolling stock.  I am sure if the current was slightly higher and more instantaneous, the PowerCab would go into protect mode. 

This doesn’t mean this is the best way to protect the PowerCab but until I install a real protector, it will have to do.

I am tending to lean toward the DCC Specialties PSX breakers. Flexible, functional and future DCC worthy. I would welcome comments or corrections.

Just for those of y'all that don't use NCE. I use a 1157 bulb with my Digitrax and it works like it's supposed to. I mounted it at the center of my layout/command station, visible all long my shelf layout. And it has functioned perfectly. No matter where I stand, if I see it flash or light up. I know instantly where the problem is. And it's usually right where I'm at. LOL
