Wire staple sizes

[klineelectric]

No prohibition for uninsulated staples and the adoration for the insulated counterpart seems to be exclusive to ahj rule writers/preference- you don't see many electricians that share their enthusiasm. The use of stackers (as stated above) do, imo also, make things a less labor intensive/quicker when grouping multiple nms along framing. Usually​, if the issue arises about double decking under a staple, a simple perusal of the instructions should be enough to quell any objections- if your within listing, your good.

And yes, the insulated staples do cost more-around 2 to 3 x as much as the regulars.

I stick with regs than. I will try the stackers though as less labor is always welcome especially the older I get.

Here it's the opposite, the non-insulated cost as much or more than the insulated. I'm sure it's because of supply and demand since we only use insulated.
