I have layed my track and separated by blocks. Now it's time to wire each block. I'm running HO scale and the longest block is 12 ft with no interruptions. Most are 3 to 6 ft long with a switch on one end. I'm planning to use 18ga stranded wire for the long block for the 12 ft block, then using 20ga stranded wire for the short blocks. I will be running DC for now, but plan to convert to DCC later. Are the wire sizes mentioned above adequate for DCC? The rail drops are also 20 ga.
