Some comments please

OK chaps. Bearing in mind this is in Thailand would you be overly concerned, yes it does have a metal cover over the works.


This is a custom board made to fit in a particularly awkward space, I have a local colleague who is branding it "unsafe" but is really unable to explain what his issues are.


Thoughts?

EDIT Please ignore the Schneider labelling on the box, the guts is all non-standard it was just cheaper to buy a suitable unit and remove the works than to get a custom one made.

    As you have asked for thoughts, I will provide mine (assuming that the missing Q10 will be installed in due course).
    1. The enclosure should have an earth connection. This may be there and just not visible on the photograph.(Late edit - I have just spotted the earth connection but can't tell if it is a suitable size)

    2. The perspex cover shields the upstream terminals of the CBs but not the downstream terminals, so when they are closed it is possible to stick a screwdriver onto the live connection.

    3. The neutral connection block is not shielded.

    4. The incoming terminals for the main CB are not shielded and will not be isolated by opening the CB.

    5. It is possible (though perhaps not easy) to reach round the perspex shield and touch the bus-bars.

    Could the installation be made safer?  I would say 'Yes'.

    Would I be overly concerned?  Probably not, provided the panel is only accessed by competent persons. However I am not familiar with the local Thai regulations which it could fall foul of.
