Stupid answers come from stupid questions. How could anyone on this forum answer your question?
Go check the name plate or call the manufacturer! At a minimum, if you want some sort of an answer, how about giving us the make and model info. If you do not have an actual transformer to check, how about doing your own leg work. Let me guess, it is easier to ask it here in the hope that someone else will figure it out for you.
Well here you go, this transformer weighs 12,345.123 Lbs.
Sheesh... I must be crabby this morning. Oh by the way, when you see "sb", say hello.
