How is the wattage calculated on a TW? I assume it is split between the cores making it a pair of 75 watt transformers. and what is the safe number of amps that is can put out per-core 3.5 or 4?
And while on the topic of amps, what is the rating of breaker it would need for modern equipment?

The TW is essentially two 1033 transformers, one w/ fixed outputs only and the other w/ variable and some fixed outputs just like a 1033/1044.
Each core can deliver 4.5-5 amps continuously, and it is protected by 2 thermal breakers. For external breakers, that will depend on on the circuit and the load you are protecting more than the type of transformer.
Would that mean I would need a 6 amp breaker? I at the moment only have a LC 2-4-2 and three 11 inch coaches which use less than 2 amps DC from the wall wart. I am hoping to add the LC+ BN NW2 (single motor) when it ships and possibly double the number of coaches. With this information is is possible to determine the breaker needed?
Thanks Allin
You don't need any additional breakers unless you want to divide your track into power districts, even then it would be optional.
Thanks, I figured i should ask before I damaged the electronics in modern equipment with a short circuit, I have read they need really fast short circuit protection.
Unfortunately, what you read was wrong.
There is NO circuit breaker fast enough to protect the electronics. What you want to do is search the now voluminous subject matter on this in the forum to provide you with the answers on Transient Voltage Suppression, and as an ancillary subject, using separate external circuit breakers on the outputs of your TW for transformer and wiring protection(the breakers are not for, and never were for, protecting the trains) if you desire.
Ah, okay. Thank you for the search leads. looks like my first line defense of using SCARM to check a track plan and weighting the front truck of the scout need a little help.
