My 800va trans came with load test results showing Primary I=6.76A
with Secondary =41.6vac at 16.6 amp. Temperature rise was 7 deg C
after 1 hour. I think this should be sufficient for my Bridgeport.
I could always parallel 2 of these identical transformers if need be.
At $56 each, they are fairly reasonable.
