Get yourself a ATC fuse holder like this from your local auto parts store: https://www.amazon.com/Invinci...gid=pla-569584425010
Get a pack of 10 AMP fuses to go with it. Run them between the transformer hot output and the power master hot input. These are much cheaper/easier to replace that the inline fuse in the Lionel adapter cable. I run this setup between my Postwar ZW outputs and TIU inputs, along with TVS diodes on the outputs of the ZW.
