This from the manual might help to explain what happened:
"Dynamic power limiting allows the 620 W available from the transformer to be shared across the four outputs as necessary to power the connected loads. Up to 180 W is available to each output as long as the total power of all four outputs does not exceed the 620 W transformer rating. When the 620 W total is reached the output that tried to take more power will be limited to maintain the 620 W total....The transformer can run in this mode indefinitely and will not shut down. When more power becomes available because of a change in the demand from the other outputs it will be automatically given to the limited output...."
I think someone saw the 180-watt specification for the four individual outputs, multiplied it by 4, and got 720 watts, without consulting the manual.

Ok! This "older" guy has another (probably basic trains 101) question about the Lionel ZW-L transformer.
Some ads I've seen state 620 watt and some ads state 720 watts.
Both ads show the same Lionel #6-37921.
Which is correct? As always, many thanks.
