I have a 500VA toroidal transformer I am going to use with my UK mains outlet to step mains voltage down to 25V. I am using a 13A fuse with an RCD (30ma).
I only just realised that the inrush from my transformer will certainly blow the fuse in the plug if not trip a breaker.
I have searched and read some solutions on here where a thermistor is used in series to limit this inrush current, however I tend to frequently switch the power off when I am touching the circuit. So this method would require me to wait for the thermistor to cool every time I alter the circuit.
I have read a post where a user switches the thermistor out after a few seconds but he relies on a secondary 12V supply for this. Can anyone suggest an alternative?
