I think it would depend on the quality of the cable, and insulating material.
Never seen any problems on site with un-insulated ones.
There 14mm long so hardly push on the cable at all.
Insulated Staples. Used one for Mains/Shotgun Cable very handy, staples can work out expensive tho.
There's a new type called UTAC which is a solid plastic staple, no metal at all.
Only insulated/non metal staples if voltage higher than ELV.
I would be lost without my staplers, used correctly they make cabling look tidy.
