Colorado JW Renewal Question

[stickboy1375]

Because that was the answer they required! IMO, it was a reminder to us that it had to be protected.

gotcha... I was just wondering bacause of all the options...

What about 250.52 A-3 (is the question about the conductor as an electrode, which would be #4, or the conductor connected to the electrode?)

 

[lbudden]

Sorry, I only read the first page of this topic---jumped in too late with my 2 cents worth......
Disregard.......

Good evening group, I'm new here and was reading this question, I also looking at this same test and I thought the answer was #4 according to the NEC 250.52 (3) "concrete-Encased Electrode" but then again I may not reading the question right.
Thanks and good luck to the Colorado bunch taking there renewal test...Les

Looking again at the question:

The minimum size copper grounding electrode conductor required to a concrete-encased electrode is...

I believe this question may well have been to catch people off their guard. The question is clearly asking about the minimum GEC to the electrode, not the minimum wire size that can be used to make an electrode.

In my first test (the sit-down) for both the wireman and the journeyman, when they asked about 250.66(A) or (B), it was clear in their wording of the question:

Where the grounding electrode conductor is connected to a concrete-encased electrode as permitted in 250.52(A)(3), that portion of the conductor that is the sole connection to the grounding electrode shall not be required to be larger than ________ copper wire.

The questions were worded with that peculiar "sole connection" language that is trademark to that section.​

Edit to add - well, I passed it.

I'm working on a little side project, and in reviewing a pertinent section, I came across something I hadn't seen before (amazingly, considering the section, and how much pounding it's received!)

Here's the test question that immediately lept to mind as I read the section again:

In a dwelling unit, how many receptacle outlets are required on a 4-foot by 8-foot kitchen island with a cooktop installed along the long dimension?

A.) 1
B.) 2
C.) 3
D.) 4

I just saw 210.52(C)(2) again, and realized I probably answered wrong:

(2) Island Counter Spaces. At least one receptacle shall be installed at each island counter space with a long dimension of 600 mm (24 in.) or greater and a short dimension of 300 mm (12 in.) or greater. Where a rangetop or sink is installed in an island counter and the width of the counter behind the rangetop or sink is less than 300 mm (12 in.), the rangetop or sink is considered to divide the island into two separate countertop spaces as defined in 210.52(C)(4).

Since they gave a depth of the island at 4', should I naturally know the normal depth of a cooktop and know how much space is behind the cooktop?

But they don't say WHERE in the island the cooktop is placed. If it is at the end of the island, it wouldn't matter, because it doesn't break the countertop into 2 parts.
Generally, a cooktop sits in a 36" wide by 24" deep base cabinent, so in this case you should have 24" behind the cooktop.

concrete encased electrode

concrete encased electrode

I took my co. renewal last night & passed. I came up with 4awg, I found it under250.52 (A) (3) the heading says (concrete-encased electrode) & 4 awg (8 lines below.) There was a Q that said "on land the service equip. for floating structures & submersible equip.shall be no closer than 5 ft , 10 ft 15 ft or 20 ft.(horiz from the shoreline.) I couldn't find the answer but I was going with 5 ft because related art 553 (floating bldg.) 555 marinas & boatyards didn't give a distance under location but stated "shall be ajacent but not in or on. Later I found it in art 682 (natural & artificial bodies of water. 682-11 5 ft. The index was no help finding that one. I'm a new member , this is a great forum. Thanks everyone.
