Proteus rcbo Went bang

[cliffed]

Existing proteus rcbo went bang,any one had a similar problem,I haven’t switched back on yet.
The DB about 10 years old,don’t need this hassle.

See the clean 6A MCB in this photo - I fitted this a few weeks back...

the previous one gave up the will to live - as you can probably tell, the CU had suffered some water ingress .............. from the old leaking bath above which has now been all replaced

A nice shiny new CU has just been fitted!

Was going to say that bus bar looks iffy

nothing goes bang without a reason !

Agree I was a weapons technician in the forces and nothing goes bang without a cause and trigger!

And that CU has seen better days. Given the water ingress I would have replaced it then, not try and dry it out hoping for the best.

Replaced rcbo switched on &........works fine,the other one test button failure.

Is Hager crap too? Fitted a 6A rcbo (on a new circuit with satisfactory dead tests). On for about three minutes and it tripped. Pushed the toggle back up and .... bang.
It can happen with all makes

I wouldn't touch any proteus materials that's are cheap and poorly made. They put in so little effort that the rcbos and mcbs sometimes don't even fit properly in their own boards

Remember that consumer unit Tel had a few months ago after fitting protective devices the cover/lid cut out did not line up.

Be concerned regarding high resistive connections (poor metal to metal contact).

they had one in our local CEF and the breakers were all sitting slanted sideways after being tightened, great advertisement

Proteus and M2 are not the best, but Hager and Wylex are equally poor in my opinion. The only really decent board is Starbreaker, everything sits straight, and there is no possibility of installing a device incorrectly as is the case with both Wylex and Hager. With Wylex the whole assembly slides on the din rail, you have to make sure nothing moves during connection or the cover wont fit, junk.
