I'm still pretty new when it comes to wiring for carpet layouts. Now that I am expanding past a simple oval with a siding to something that will weave from the living room into our guest bedroom in our apartment, I would like to know how you guys hide your wiring? The same layout style of layout will be done when I have a basement to work with "carpet on a raised table and shelving." I would assume it would be beneficial to have a bus for the track power. Also, for lit accessories, do you generally use track power or accessory?I understand using track power would be simpler but I like to have my accessories constantly lit and not depending on my track voltage. All my switches will be O-36 Manual for cost and simplicity.
Also, I am thinking of building a smaller, control stand that will have my CW-80, room for a future dedicated accessory supply and maybe accessory switches for the floor layout.
When I am able to build, I will have bus lines under my table and shelving for both track and accessories for 12,14, and 16 volts with 12 being the most common.
Burned wire marks into the carpet one time with a ZW. We were banished from the carpet forever. It may have been the suggestion of making little slits since there were now marks of opportunity showing... Have given kids FastTrack ovals, agree the notching has worked best. Especially when paired with a modern transformer!!
