Upgrade of DCC Electrics on Existing Customer Constructed Layout

As probably the most experienced installer of ZTC DCC and DCC apparatus in general we are often asked to advise on customer constructed layouts and customer installed DCC systems particularly where the client is unable to solve a problem. This particular layout was causing the owner problems with return loops at each end of the layout. We have replaced the ZTC550 booster units and ZTC 560 transformers with simple high performance reverse loop modules that have LED power indicators and blinking LED's to show when the module is in reverse polarity mode. The removed ZTC hardware has been used to break the layout into power districts protected by non ZTC circuit breakers improving power distribution and improving reliability bringing stability to the layout. The circuit breakers also have LED indicators to show power is present on the block and an LED to show if the block is short circuited. If one block short circuits the remainder of the layout continues to operate. The client is now able to operate the layout as he intended..
