    Haven't you ever seen an ECEE (Elevated Concrete Encased Electrode) before. It is also referred in the trade as a Whatfer instead of a Ufer.

    Yeh, that was my explanation to the owner. At that point, cost didn't matter.

    I'm not kidding when I say this is priority number 1 on the electrical installation for these guys. Along with the affidavit, we have to send pictures of ORANGE IG receps to the POS vendor before they will come out to install.

    My supplier ran out of orange receps once, and I used ivory IG receps with the orange IG symbol in the corner. It turned into a crap storm.

    lately, anything with orange on the top of it gets people riled.

    I see the problem; fitting instead of a bushing on the EMT... wait, no, they didnt use a rebar to EMT fitting... clamp not listed for use on rebar (ECEE LOL)... I think I'm close... aha, I have it: they used a red wire for ground! That's it! everyone knows you only use red wires on bombs when there is a 50/50 chance of cutting the wrong one with less than two seconds on the timer!!
    Electricians do it until it Hertz!

    This demonstrates the sheer stupidity of people. You require an orange IG receptacle but do not even know enough to check and see if it's actually properly grounded.

    I have seen isolated ground requested tons of times. At lease half the time when questioned further, the "specifier" is only envisioning a dedicated ground wire to the nearest panel. I love it when an Electrical Engineer specifies isolated ground and then doesn't provide any isolated ground busses or an additional wire in any of the conduits. I hate it when I have to bid one, because I understand the requirements and I assume there is usually going to be one idiot who doesn't. There was a thread here yesterday that someone was asking about whether to bid to code or spec. Here is one that I will usually just clearly state in my proposal, "Excludes additional wiring or components are required for isolated ground that are not shown on the plans." I will usually highlight it.


    I know what I don't know, and I know where to go to find it!

    Orange grounding conductor and no grounding bushing?
    The more they overthink the plumbing, the easier it is to stop up the drain
