External PSU shuts down the breaker

Hi! I have a Gold Note PH10 phono and just received the PSU 10. After I turn on the PSU, it shuts down the breaker in the house. I have tried to plug in without connecting the phono, same results. It was all right when I tried in a HIFI shop, and worked well, even connecting to the phono. I would be suspicious, but every single component is working good (with higher load also), except the PSU.
What can it be?

This unit has a low voltage linear power supply for a solid state phono preamp/equalizer.  It should not have a massive bank of capacitors that would draw enough current to trip any kind of breaker.  I would not fool around with something that might be faulty--not just because of safety concerns, but, also because I would not want to fry other downstream components.

Is it possible the existing circuit is close to overload?

What happens if you plug in a house lamp?

My bad for not checking first.

I have no idea what electrical safety codes are in your country.


EDIT:
Make sure the PSU is for 220Vac nominal.

This unit does have an integral fuse. Unless that fuse has been replaced with something far larger than required, it would be quite difficult for it to be tripping breakers on its own.

The GFCI / spark arrestor type breakers might though.
