2020 NEC Changes series: 250.68(C) Grounding electrode conductor connections

I appreciate your directness while saying plumbers are evil. They really are.

Great video Ryan! Always informative and I love that you keep it real!

Thank you Sir I followed you Your Lecture is very easy for understand to NEC

Hey Ryan, We never intended for the concrete encased electrode to be used as a bonding jumper to interconnect other electrodes. Although it was never tested as you mentioned, and that is one of the reasons we clarified the language in the 2020 edition. We did allow it for the metal frame of a building because 1) it is NOT likely to have the continuity of the metal frame interrupted the way metal water piping is likely to be interrupted. and 2) it is suitable for systems that have ungrounded service conductor that exceed 1100 kcmil CU or 250kcmil AL, in other words, no matter how small or how large your service is, the metal frame is akin to a properly sized wire type bonding jumper. With metal water piping it is the same issue, (as long as it is connected within the first 5' as it enters the building) the metal water piping will work again for the smallest service or the largest service. Rebar (concrete encased electrodes are a very different matter. For example, if you had a 3000A service that includes metal frame and a concrete encased electrode, the 4 AWG connection to the electrode is not the same as a 3/0 connection needed for the metal frame and using the 4 AWG to connect metal frame would not meet the requirements of the NEC.

Good lecture. Thank you!

Great explanation. Thank you.

"spliced with water" so like a toaster in a bathtub? XD, made my day.

Hey Ryan, I'm enjoying your videos, but i have a confession to make. Around 15 years ago or so you inspected the electrical install on a new build church, i was using the white wire iin a 12/2 mc cable as my switch legs in every room, you told me to mark them all black, i promised i would and you signed off on 4 way. But i never did LOL!

Very good that makes very good sense.👍

Thank you Ryan!!

Since rebar does not come in 1000' lengths (usually max 60'), the sections of rebar would have to be electrically connected together, not just touching with a piece of rebar wire tie around them. Also, unlike a water line whose location is well known and makes a huge mess when it is cut, someone could core or cut into the concrete right through the piece of rebar that is being used as the grounding conductor and never be the wiser.

Kansas City, Kansas / Wyandotte County requires copper waterpipe to the water meter still.

That’s awesome you kept that spliced with with water 💦. Bravo Ryan 🤣

As I heard you say “splice with water” I knew I’d already seen this video! 😂😂😂

Mis speaks, and then takes a big swig of his beer...haha, thank you for being a regular dude!

Great video . Happy knife life

Lol when I heard spliced with water my brain crashed but then was rebooted when you questioned yourself 🤣

When's the last time I saw a copper water pipe underground? Every day lol

So if I may ask, can we then use Ufer in commercial or residential as grounding method?

Plumbers? Evil? That kind of speech is gonna get my electrodes purposely cut.
