TAP CON for bonding jumper

[codeworks]

we see our fair share of wierdness around this neck of the woods: i went to do a "meter release" this morning, and the fellow had used a tap con screw as a bonding jumper in the panel to bond the neutral, gec and panel board, wow! (bang head here, but it won't work)

codeworks,

For us "under knowledged" folks, can you please cite the applicable code section that your

application violates ( either the IRC and or the NEC )? I'm not familiar with the term

"tap con" screw!

Thanks!

250.8(A) NEC.

A tap con concrete screw does not meet the requirements for bonding connections.

Did they at least scrape the blue paint off?

Funny I was wondering the same thing.

What is the application? Was the tapcon used to mount hardware? This thread needs a picture.

I could see that one being pulled over on an inspector, some times its hard to see the color difference from tap-con blue and grounding screw green in a dark basement?

Good catch codeworks, thanks for the heads up!

What "blue paint"? Isn't the color manufactured in to the screw itself, or

is the color applied post-manufacuring, ...in some type of metal

anodizing process?

In the ES Report, in Section 5.9, ..the tap con screws are restricted to

"dry, interior use only".

Tapcons are coated with a blue Climaseal® coating. This coating provides exceptional corrosion resistance.

So, if the subject "tap con" screw did not have the coating removed, it would

fail on two counts in the indictment. (1) the coating is a barrier to an

effective bonding connection, & (2) the "tap con" screw is not listed for

exterior applications.
