Hello, with regard to underfloor heating mats, the new regs 753.411.3.2 state, "in the case of heating units delivered without exposed conductive parts, a suitable conductive covering, for example a grid with a spacing of not more than 30mm shall be provided on site as an exsposed-conductive-part above the floor heating elements ". the unit I use has an earthed screen around the cables. Whats the purpose of the above, it wont provide any mechanical protection ?. can someone enlighten me, Cheers Drayton.:confused:

Because this must be on its RCD, its ensuring that any breakdown of the live conductors gets picked up by the earth system (hence the screening or grid)
 
Yeh, Thats my point , the wire mat system has an earthed screen which if there is a breakdown on the live conductors, the RCD will trip, I dont get why there needs to be a separate exposed earth grid, or am I being thick.
