Pre-drilled holes in trunking EICR Code

[DPG]

I thought 'deliberate action' had been added to that or am I imagining it?

Good point. Bet 'deliberate action' isn't defined anywhere!

 

[DPG]

"521.10.1
Non-sheathed cables for fixed wiring shall be enclosed in conduit, ducting or trunking.
Non-sheathed cables are permitted if the cable trunking system provides at least the degree of protection IPXXD or IP4X, and if the cover can only be removed by means of a tool or a deliberate action."

The last bit about deliberate action is a little vague in its intent...

Good find. Cheers!

I hadn't come across IPXXD before. From a quick Google it seems a way of establishing safety by testing - using a probe 1mm dia and 100mm long and checking it cannot come into contact with live parts. As stated, single insulated cable is not regarded as a live part.
It seems a bit extreme to poke a probe into every hole in a completed length of trunking, but doing a sample would be one way of demonstrating the trunking is compliant (that is assuming the trunking has a cover requiring a tool to remove)

I think there's grounds for challenging the C2, unless I've missed something

From Voltimum (so it must be true ):-

IPXXD: ​

For this degree of protection, only the third letter ‘D’ is relevant. The letter ‘X’ signifies that the first and second letter protection levels are not specified. BS EN 60529:1992 + A2:2013 states the requirement for ‘D’ as the degree of protection required for protection of persons against access to ‘hazardous parts’. An access probe having a maximum diameter of 1mm and maximum length of 100 mm, when inserted into any gap or joint within an enclosure with an applied force of 1 Newton, must not make contact with ‘hazardous parts’.
