Crabtree c50 breakers

Are these worth selling or just get rid? Saved from a recent mains change

I believe you can still buy new ones so probably not got much value second hand.

Can you guarentee they work and will actually trip under fault conditions?

 

[dadof3]

Is that a nice way of sayin get rid....

No not at all, please read my question again.

 

[dadof3]

The answer to that question would be no

Okay fair enough mate, now if you had tested those breakers before removing them and they did operate then selling them could have been an option, as you have now confirmed it isn't the case I would advise you not to sell them, HTHs.

What would be your suggested test method to ensure operation to the manufacturer's published characteristics?

I wouldn't test them, it wouldn't be possible unless under controlled conditions in a labatory, I would throw them away, end of, I was trying to get the OP to answer that question, perhaps you can get it out of him lol

 

[HandySparks]

Fair enough.

How can you test any breaker to operate at fault conditions unless as you say in test lab conditions, so would you connect a new circuit to an existing c50 mcb in a db not knowing if the mcb will operate in a fault condition ,(or for that matter any make of mcb)

I can't see the photo, but if it's one of those old brown/black bakerlite jobbies i'd throw them straight in the bin where they have always belonged!! Even the DB's they were used in were bloody dangerous...
