Protecting a Lionel KW transformer.

Ingeniero No1OGR Forum Member

I am using a Lionel KW transformer to power building lighting and other accessories.

For the lighting, I am using the A and B variable outputs as they give me the versatility to adjust the brightness according to what I need at the time.

I measured the output of the A-handle for a small city block with 10 buildings, and the brightness I liked was with a setting of 14 volts, and the resulting current draw was 3 amps. This is about 42 watts, which I guess would be OK for the KW, but I am not sure.

As most of you guys know better than I do, the KW has a rating of 190 watts, consumption I believe; but I really do not know how this is allocated among the two variable and several fixed outputs.

What would be the appropriate rating for a fuse or circuit breaker for the KW variable A and B variable outputs?

Thanks!
