EICR on a Motor Control Centre Panels with BMS

Auryn Morgan

In my world it has become a hot topic regarding inspection and testing of MCC panels and where the limitations are justifiable.

The buildings in question are approx. 20 years old and operational as educational establishments

My current thoughts are that a visual inspection of the panel with end of line ZS readings and insulation resistance down stream of the contactors/ relays is a sensible approach eliminating the sensitive equipment. 

Some consultants are suggesting otherwise which on the face of it doe not appear a reasonable approach.... they are even suggesting that the control wiring is a requirement. 

I'm keen to have further opinions as to where the limitations reasonably lie for the LV circuits within these panels.

Appropriate referencing to support would be really appreciated 

Thanks for your help

    In this recent installation on a dairy farm, the electrical contractor left isolators for connection of motors and control equipment by a specialist milking parlour contractor. The photo shows only a small part of a fairly extensive system. An EIC was required as part of an application for a sizeable government grant. The electrical contractor duly provided this but only up to the isolation points. Not one stick of certification was provided for the installation on the other side of same. 
    Seems to be a very common situation throughout all types of industrial installations.

    It's not just in commercial/industrial situations - typically the same happens in domestics for central heating systems (which getting far more extensive these days with per-room zoning etc) - it seems to fall under the heading of "too hard" for the typical electrician and "dunno about electrical testing" for the plumber.
