Isolation for maintenance

[TailSpin]

Now that does, sound wrong.
All equipment of all sorts in the one panel, should, really be fed from the same incoming supply.
That is all barring interlocks between machines say.
The lighting should be fed from the incoming side of the main isolator in suitable cable to it's own circuit breaker/isolator.
Who CE marked the panel?

Hi Paul
this is the thing the named panel has in affect two supplies the main 3phase supply and a multicore cable also comes in the panel to a row of mcbs. This then feeds a transformer to indicator lamps to show supply on faults ect . Other mcbs fed fans ect.( 230v )
The Main Isolator that feeds this panel kills all supplies.
A local contracting firm built the panel no apparent CE mark on panel.
So is this just a case of clear labels if so is there a BS for this type ? I guess Isolate elsewhere would do or might I find the answer in say BS EN 61439-2:2009 ?

Regards
John :confused5:

If it is for a machine try 60204-1.
Ask the manufacturer to come on site with their copy to go through the design with you.
If they don't have the standard, then they should not be building panels for machinery.
