Advice sought - isolation transformer inrush current limiting

I've got a 1KW isolation transformer that usually trips the 15A breaker at
the breaker box when I turn it on, load or no.  I'm considering installing
a pair of NTC thermistors on the input side of the transformer, but I've no
idea how to size them or if there might be a better option.

Any advice would be appreciated.

Cheers.
