My Buddy Joe M. (EC) has a job to wire a dairy barn. The concrete slab was poured before they even called him for the job, so needless to say, the equipotential plane was left out.

Having grown up on a dairy, I know first hand the importance of an EP.

Is there a fix for "retrofitting" an EP to an existing slab? Jackhammer down to the rebar? What does Joe (and I) do?

i suppose that there should be one, as not many builders are calling for an electrician before the pour.

Yeah, a Ground Ring...and bond *somewhere* to the rebar as well?

Steve, IAEI has a similar thread and I posed the same question there...

Seems I'm getting completely ignored at the IAEI BB... Musta made an as* out of myself the last time...

Screw it... It's too much effort to do things right when no one else cares...

... OK I'm a little calmer now... I've posted it as its own thread... maybe that'll help...

hmmm,
well Virgil, no soap yet!

As a point of discussion,this is a good example of the NEC basically pushing it's wishes on other trades.
Once the code is made, it is somehow thought to be accepted practice by those trades.
However,the word usually gets out via us tradesmen in the trenches, myself i'm pro-ufer,etc..and try to convince who i can of being needed before the pour.
I have found no other mode of communication, and as yet have not seen any AHJ site 547-9 as a violation to the point of tearing up a pour ( now that would be something!) [Linked Image]

I also must add, that 547-9 is somewhat biased to chickens here. I'm sure there's a chicken association or something that could chime in!
My hens should write an ROP!

Don't feel bad. I posted the "sizing feeder conductors" thread on the IAEI. Get many opinions, but still don't know what the consensus is. [Linked Image]

Sparky, and others,

I am guessing that the IAEI BB is only for people like us that have been on these other BB's.

It is my opinion that the "Big Guns at the IAEI BB", mentioned by someone on these other BB's, are some-what muffled by their home office.

In the IAEI NEWS magazine, usually only CMP members answer specific questions with "their own" opinions.

If someone reading a post on the IAEI BB posted by a CMP member, everyone would take that as being the opinion of the NFPA 70 ( NEC )and be gospel. The NFPA ( not a CMP member) must make all rulings.

I'm feel quite sure those CMP members would very much like to make comments, But I don't blame them for not making comments.

There has been some very good, and some very bad, opinions on these BB sites.

I've made bad comments also.

I wish everyone would use NEC Sections to back-up their opinions and mention which NEC Year they are using.

Sort-out the BAD opinions and read the NEC for a understanding of the GOOD opinions.

Glenn
