EICR on a Motor Control Centre Panels with BMS

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

  • Then again from the point of view of the Electricity at Work Regulations "All systems shall at all times be of such construction as to prevent, so far as is reasonably practicable, danger." - so if something is excluded from an EICR it'll need to be included in something else (e.g. PAT in old school parlance). What constitutes a reasonable approach in the circumstances is of course debatable, but the answer to that may well be pretty similar whether it was done under an EICR, In-service Inspection and Testing of Electrical Equipment, or something else of the Duty holder's invention.

    Agreed, although specifically the reason I pointed to BS EN IEC 60204-1 and manufacturer's instructions, is that there is (in the standard at least) an onus on the manufacturer to provide recommended procedures (and periods) for functional testing and maintenance activities.
