Thanks guys,
I agree the isolation should be first for safety reasons.
But I've seen people like Mr Carlson's and some others put is second, perhaps they have their reasons.
I was considering a soft start using a relay but the NTC is a better idea, especially since my isolation trafo is only 500VA, I think I've already got a 3A NTC from a switchig PSU which will do nicely.

Cheers
