di-electric mat in front of the high voltage switchboard
(OP)
Hello,
I am working in a industrial project. Our contractor explained that it is not necessary to provide di-electric mat in front of the 6.6KV swithcboards. The project specfication mentioned nothing about this issue. Who can tell me where is in the IEC standard that requires to provide di-electric mat in front of high voltage switchboard.
Thanks.

Good point OFG. Casters on breaker carts will tear up [typically "20kV"-rated] rubber matting in no time—making their use completely counterproductive.

If they MUST be installed, the best approach is to cut them in short lengths so you can roll back a bit out of the way when rolling a breaker out. But is was replacing one of those "rolled back" mats that shut a plant down once in my experience.

A lot of years we try found some standard for this issue, nothing.
I agree with Zogzog and Dave , isn't add something for safety, aspecially for the newer metalclad SWG, all roll out parts make by plastic.
From other hand, we see in lot of areas continue use them, Oldfieldguy, right, in lot of tenders is included.
Best Regards.

Is there any statistical record or info on such matts becoming tripping source/work hinderance;to share?
Moreover I feel as if this is somewhat a marginal protection against worker's forgetfulness for protective footwear use!

If gear is grounded properly, safety should not be an issue.
