Add a separate PCP panel to operate your Power Cab in other places or on other layouts. Add the P114 transformer and you will only have to move the Power Cab.
Please note this is not the standard extension plate for NCE systems using the Smart booster SB3a or the Power Pro system box. This device is exclusively for use with the Powercab starter system and it's own small P114 power supply.
If you need just a simple extension panel without the Powercab power connection to enable you to use an accessory cab in a different location then order the NCE UTP universal throttle panel. You can even use a UTP with a Powercab as an extension for it's other cab if you have one.
