40 amp MCB live when off? Faulty?

Remind me of a Big Clive teardown

Okay, try again. Reminds me of a Big Clive teardown

Yes, it could be fake I suppose. All of the others came from TLC in Tunbridge Wells - I buy nearly all of my electrical stuff from them. The Amazon one looks absolutely identical in every respect: same plastics, weight, printing etc and same packaging. Hardly seems worth counterfeit fakery for things as cheap as this. I doubt trading standard would take any interest in something under £10 like this.

It is not the price, it is the risk to safety.

At the very least Hager would want to know if there is a manufacturing fault or there is a dodgy side-trade in fake/failed ones.

Fair point. I'll think it over how to proceed.

Might be interesting to compare the weight with a known genuine one.

No way could I resist opening that up and having a look.

And definitely report it. If it's a bad batch then action needs taking rather than leaving them in place ready to cause an incident when they don't trip on a fault.

If you do decide to open it up yourself, take plenty of in-focus photos before and during the dismantling process!

I weighed it versus a genuine Hager from TLC. Using my bakers scales which weigh digitally to the gram. They are identical. Shaking and it tapping it does not rectify the fault. I can't get it apart non-destructively, so I will be returning it for a refund and have already left a negative review (which may well get blocked).

This is actually the secon Hager MCB we have had fail. We had a defective one in a different CU in a kitchen about 2 years ago, and in that case it just tripped constantly when there was no circuit fault. That one was identified by an electrician who didn't bother with any tests (and said he was not certified anyway - he was near retirement) he just swapped the wiring over and put tape over the dud. I keep meaning to whip it out actually.
