552PS Tripping Electrics UK

hey all

I’m setting up the system after having it boxed for a year.

Having issues with the 552 which is tripping the electrics when powered on, even when it’s not connected to anything else.

I’ve had a separate system feed installed and have 5 double sockets (separate fuse for each) to a single consumer unit installed during a house renovation

All other units power on fine. 2 x 500’s hicap, super cap etc etc. I’ve tried plugging into a different socket with no joy

Any ideas ? Guessing could be an issue with the power lead or burndy but everything was working fine before being boxed up !

It’s doing my head in obvs :roll_eyes: :rofl:

Any ideas ?

What happens if you plug it in within another part of the house not these sockets?

I’ve not tried that so will have a go

Try it on a different ring main and see if it trips that out.

There may also be an issue with the circuit breaker on your new supply and the inrush current is tripping it

Does everything else work OK on your new supply

Yes - everything else powers on fine. I’ve tried a different socket from same consumer unit and same issue.

Could be this;

Can you confirm exactly what is tripping - MCB, RCD or RCBO?

Maybe a picture of the consumer unit?

Circuit breakers trip for a reason! What exactly that reason is depends on whether it’s an MCB, RCD, RCBO or whatever: they protect against different faults. Don’t rule out the possibility that yours is actually doing its job properly and tripping because there’s a fault.

The common problem of nuisance tripping due to the inrush current when you turn on a big Naim power supply is the other thing to consider. Traditional MCBs should be Type C rather than the more commonly fitted Type B, so if you have the latter you may want to talk to your electrician about getting a suitably specced Type C.

I had the same problem with my Armageddon when it first arrived. And of course I wasn’t going to leave it on all the time like the amps, so it happened with annoying frequency. The advice from the dealer was to up the rate of the MCB to 32A. Never a problem after that.

Worth noting that without fully investigating the design of the downstream circuit, just uprating the protective device can be dangerous.

As Neil says, you need to get it properly checked out first. We had a convergence of advice from dealer, installing electrician, and Russ Andrews who supplied the separate consumer box.

This is the board. My spark says type C are normally for commercial installations but is happy to help and find a solution

Indeed - my response was more for the benefit of others.

Fusebox fuse box envy :heart_eyes:

If the radials are wired in 2.5mm or larger, changing to 20A would be an option too.

Sorry, missed that. Point taken and post edited.

Maybe this is why my Atom HE sounds so good. Nothing will blow this.

They are 10mm

I had this with my 300, my sparky changed my trip to a C, job done!

Oh wow! You have a few options then.

Unless it’s an earth leakage fault. :open_mouth:
