well i guess i will have to get around to doing a plug in test and see what it is i have.

also my lift calibration might be significantly off, these might be a bunch heavier than 20 lbs each,, it isn't like i lift stuff daily that i am aware of the weight like i would be if i were a UPS or FEDEX delivery guy :)

i just can't imagine that these would be much less than 2kva each, but we shall see i guess.

i don't really need them to be 2kva, i would be ok with them being 1.5kva each
for my needs and even then they would not be at that load rating for very long.
the majority of the time they would probably be well under 1 kva each.

one just doesn't see these things with enough regularity around here to have a frame of reference.

with scrap prices going to the sky, there will be even less of them laying around.

i got these just hours before they went into the scrap rolloff dumpster for recycling.

Bob,

I've got two 3ph xformers, different sizes, with power ratings on them. Both are 208v delta inputs and 32v wye outputs. The coils are as you described, 15 guage wire primary and 1/8" x 1/4" square wire secondary.
I weighed them both to give you some numbers to crunch.
Smaller one is 52 lbs with an output of 65 Amps
Larger one is 77 lbs with an output of 107 Amps.

Hope this helps

Fishbonz

fishbonzwv:

thanks for the info

i need to get a scale, i may be far too light on my estimation
i have been installing and reinstalling a 70lb pto on a truck
for the last 2 weeks (ugly story) and never realized that it was 70lbs
till i looked at the shipping slip today!

so my estimate of 20lbs on these transformers may be off a bit
they might be 30 or 40lbs each,, i dunno :)

my calibration of weight is getting a bit off as i age i guess.

some days 10lbs feels like a hundred, other days who knows
one thing for sure,, a hundred lbs is always too friggin heavy for me
to want to wrangle with.

thanks guys
bob g
