When you say stored for a year, is there a chance some moisture may have got in to the kit? If not already done, I’d leave the kit unboxed for a few days to let it air-out.
As others have said, C-type breakers are far better than B’s for this kit.
Thanks - yeah no moisture and everything kept in original sealed boxes.
Think type C or at least a 32a amp breaker might sort. Here’s hoping. Was hoping to have music this weekend 
Hi @CautiousLip
Have you tried using a different power lead to the 552ps? So as to eliminate a faulty powerlead.
Have you tried taking the 552ps into another room and plugging it in a socket that is fed from your non-hifi consumer unit?
Have you tried plugging it into each of the sockets fed from your hifi consumer unit?
Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A.
Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device).
Thanks - I’m gonna check the powerline tomorrow and will report back. I’ve tried different sockets that work fine with other components which work ok
Check your Powerline IEC is fully inserted and pushed home beyond the first resistance - see the FAQ here which explains all. If not it will arc and likely trip out the breaker or even blow the internal fuse.

Thanks - yeah - did that already but will have another check
For the avoidance of doubt and for the sake of clarity: have you plugged the 552ps into each and every socket fed by the hifi consumer unit, and have you plugged it into a socket fed from your non-hifi consumer unit?
They are more commonly used in commercial installations because there are lots of more powerful appliances that may require them. That doesn’t mean they can’t be used domestically. Maybe try explaining to your electrician that the toroidal transformer in a Naim amp is unusually large for a domestic appliance, and that the inrush current generated when they are powered up is known to repeatedly trip Type B breakers.
Assuming, of course, that you have first eliminated the possibility of an actual fault that is causing the breaker to trip because it’s doing its job properly.
Had done this for my 500 - changed to C
Had a play around this morning. All connections are fine and it’s now actually more than one unit that’s tripping off the breakers.
I’ve got everything powered on now but only can hear the tweeters with music playing. The woofers pop when powering on or off the bass 500 but nothing when music playing.
Any ideas ? As far as I know everything is wired up properly.
system is
Ndx2/555
Nac552
Snaxo / Hicap
2x500
Kudos 505
Have you tried swapping over the left and right connections to the amps from the snaxo

Hey everyone
Thanks for your input.
I’m now up and running after having my spark install some commercial C type breakers which were apparently hard to find for my consumer unit type
warming up nicely.
