If I am installing in-line fuses between my z4000 transformers and the DCS components, where is the best place to install the in-line fuse?
Keep in mind that the smallest over current protection most likely will open (blow) first regardless of position in the circuit. These fuses, (7.5amps max), were positioned between the Block Power controllers and the tracks on the power side of the circuit. Commons are complete back to a common bar and the common side of the two transformers.
