Hi Ry...

BIL  is a maximum rating for the breakdown voltage level in the given
container...
e.g. at 60KV the insulating material in the case will breakdown and sparks
will fly :)
BUT this doesnt mean the core can handle such voltages  normally BIL is
used for
lightning strike/surge ratings

30 c AMB   = 30 degrees centigrade higher than ambient temperature    so if
it is 30
degrees centigrade outside air temperature,  the case/container can go to
60 degrees
centigrade inside while the trannie is pulling 750VA.


hope this helps
