UK IP 65/IP44

[Neil B]

Main switch room as ingress of dust , the switch room also has many openings to allow the ingress of dust. A recent EICR as coded the Distribution equipment in the room C2 not fit for external influences . One side of the room as an 800A BS 5709 isolator supplying a busbar with 10 BS 5709 isolators supplying various pieces of equipment. Can’t find a decent IP65 MCCB board. Or could holes be sealed in the switch room to minimise the ingress of dust (they should have be done to prevent the spread of fire) and an IP44 MCCB DB used.

If you do have to upgrade the switchgear, an alternative solution is to house the whole setup inside an enclosure.

This is pretty commonplace in industrial situations where everything is housed in the one panel.

Obviously each cable will need glanding or similar through the enclosure (just stuffing glands) then finally proper glanding/terminating into each item of switchgear as appropriate.

Depending upon who has access, you can actually use "downgraded" ip kit within this enclosure.

Obviously, only the thing to do if you absolutely need to replace most everything, if it's just a couple of things, just get a higher ip rated unit, or enclose each one individually.

A 10Way TPN MCCB Distribution Board is qùite large ….. would be difficult to put in an enclosure….however I have seen the gear tray /pan removed from a distribution board & fitted in a stainless steel enclosure in a food manufacturing process area. Not sure if that complies with BS 7671 though???

As long as the enclosure is big enough it will be fine, enclosures are readily available in that kind of size and much larger.

however I have seen the gear tray /pan removed from a distribution board & fitted in a stainless steel enclosure in a food manufacturing process area.

You can buy the pan assemblies separately for building custom units like that, no need to remove it from a standard DB.

Not sure if that complies with BS 7671 though???

Yes it complies as long as it has been built to and certified to the correct standards, which any switchgear manufacturer should be doing.

Custom switchgear like that is pretty standard for medium to large installs.

Thanks for the information much appreciated
