Modular 18VAC Accessory Fused Power Box and Distribution Board

 

This is an example of a modular 18VAC fused power and distribution board that is used for accessory lighting and block signal power. Input power is 120VAC. Output power is 18VAC. The board provides fuse protection and can be used with my wireless 120VAC power on/off control system. Three MTH 50-1020 termination panels allow up to 72 individual circuit connections to accessories.  My model railroad control and electrical system is built using modules such as this one.

 

Schematics for each module are typically added to the underside of each board for reference.  See the attachment for a typical schematic.
