Neural connections inaccessible on Lewden RCBO's

Alan B

Hi

I am coming across more curve consumer units with Lewden RCBO's in and they are causing me a dilemma.

As you will see in the picture the line conductors pass straight in front of the neutral terminal screw, the only way to check torque on the neutral is to remove the line conductors or risk damaging them.

So far providing the line terminals are tight I have not checked the neutrals as I believe i would be doing more harm than good with work hardening and flattening of conductors, and noting this on my report.

What would you do in this sittuation?

    'Neural connections inaccessible on Lewden RCBO's'

    This is indeed a headline ... Fully intelligent RCBO's now available.Laughing

    I guess you're there with a brain surgeon trying to get into the 'neural connections'?




    Sorry ... had to post this, I was looking at the thread title trying to work out what was wrong, until I saw the missing 't'.

    Yeh, but the important thing is that Alan B knew what he meant, and we did as well.

    Hi graham, perhaps you were forgetting the over tightened connection that was allegedly the cause of the Clandon Park Fire?

    No problem with my neural connections.

    Let’s not beat about the bush, there is no way to to test an existing termination for torque without loosening the termination then retightening it with a calibrated tool. 

    And there are arguments I've heard, regarding the fact that even if you do tighten to the correct torque, there's no saying it will stay that way ad infinitum (loosening over time) ...

    I wasn't picking at the question, just the fact that I found a minor typo amusing "neural" rather than "neutral" - leading to "intelligent circuit breaker".
