100 Days of Article 100: Equipment Grounding Conductor

[@alexsoanneso7873]

On another level 💯 you got a follow here.

[@intheskymusic]

It's not just the material, but your experience that permeates through these videos that makes them invaluable. Thanks a lot bro.

Another excellent video. I work for an electrical contractor when I'm off schedule. We always pull an equipment grounding conductor for redundancy. I like the "belt and suspenders" approach...

[@electricianron_New_Jersey]

Ryan, I usually learn something I didn't know before watching one of your videos and this one is no different. I did not know about the MGM Grand fire being caused by an electrical ground fault condition. That's news to me. Thanks for relaying the message.

[@elc2k385]

Very good. I learned about how paper covering in AC ia different from the plastic in MC, also learned about MCI-A connectors for the MC with the aluminum wire inside, and a bit about what a busway looks like. Also, about the flexibility stuff with the flex. Thanks, Ryan.

Thank you im an apprentice and this is so easily to follow great job sir.

[@jirehelectric]

Very nice video, i always run agreen equipment grounded conductor wheather are raceways or not. Can you make a video explanation of raceways.Auxiliary gutters some electricians say are ' raceways ', electrical boxes, switchgears because have busbars.

[@chicagoflipsters6772]

You have more video about article 200 300 …? Just love your work ❤

[@jimlopez8197]

Love Ryan’s videos BTW.

One thing I could never locate in NEC is the size of bonding wire that runs from a grounding bushing that only contains a ground wire. At the large hospital/ research center that I retired from 13.2 KV switchgear rooms might have up to 10 underground conduits only containing copper ground wires that all went to a 1/4" thick 4" wide by 2 to 3' copper buss bar. Some of the ground wires were at least 250 MCM but they only looped a #10 copper wire from all the grounding bushings to the copper buss bar. A few locations used #6 wire. Often thought they should have used a heavier wire. In Philadelphia they outlawed all aluminum ground wires ( 7/1981 ) so they never provided a clear answer with the use of using hospital type MC that contains a #10 aluminum ground wire. Contractors stated that the insulated green wire takes care of grounding.

Not to stoke up that debate...but I kind of like to think that it's the system that is grounded (per your solidly grounded video) more so than the individual devices and equipment...whereas the EGC (EBC?) does bonding first and foremost. The UK eschews both terms in favor of CIrcuit Protective Conductor (CPC)...which is certainly accurate, and does successfully avoid this controversy

[@royamberg9177]

How many times have conduit came apart. Run a ground wire

[@camoapajafa]

Great video sir, Hope you're doind well Mr. Ryan. Thanks.

[@MrMaxyield]

Informative as always. Thanks Ryan..⚡😎👌

[@KhizarHayat87]

Great video!

[@JesusCruz-wt2zp]

Please keep doing this videos, thanks

[@--JohnDoe]

Mr. Jackson. I trust noone, but the only two people I trust to decipher/explain the nec to me is You sir and Mr. Holt.

[@RyanJacksonElectrical]

Thanks!

[@sjain9383]

You are awesome👍👍👍👍👍🙏🙏

[@pjmcinnis1188]

Hey thanks but I’m new to the trade and want to understand this.. I got confused on using the raceway as equipment ground. so you saying anytime I run emt, rmt,imt that I would not be required to run a green ground wire? so why do they do it? I worked around a lot emt and that’s all I’ve ever was taught.

[@garbo8962]

I had a lazy cut every corner chief electrician who never ran a ground wire when running EMT. A 1.25" EMT that he ran without a ground wire pulled apart at a coupling due to another trade played with conduit to snake a pipe between conduit & wall. When he was attempting to reinstall the conduit a 480 volt wire that got kicked touched the conduit ( ungrounded ) and got a severe shock along with chest pains. After that he started running ground wires. Like to have a solar for every time I came across an EMT conduit on set screw & compression fittings that were pulled out & corroded conduit .

[@davidnobilese6124]

The same thing would have still happened if there was a ground wire in the conduit…

[@boeing757pilot]

Yes, if you're using those, you do not need a separate equipment grounding conductor because they will bond and carry fault current. We run an additional "green wire" for reduncy in case a coupling fails.

[@jimc3678]

At end of video. If EMT is going into an eccentric Knock Out in the raceway/gutter, Wouldn't a ground wire or bonding bushing be needed?

[@RyanJacksonElectrical]

The wire would not be required, but a bushing could be. It depends on the voltage. Compare 250.96 and 250.97.

[@flipcy]

Thanks for videos

[@jimmiegill3981]

Very nice video

[@realvanman1]

This was an interesting one. I had not realized that the MGM fire was caused that way. What a freak accident. I have always taken that little bare aluminum ground wire and folded it back over the armor and wrapped it around, ultimately clamping it with the connector. Could that actually be construed as not allowed since it doesn’t “follow the manufacturer’s instructions”? Seems it can only be as good or better.

[@RyanJacksonElectrical]

Usually the instructions allow what you describe or cutting off. I would cut it off, since that is the diameter of cable that the fitting is designed for. Adding the aluminum wire to the diameter of the cable probably wouldn't hurt, but it most definitely DOES NOT help.

[@jimlopez8197]

I agree and disagree. Depending on conduit for EGC depends on installation and is vulnerable to future conduit failure without disconnecting the circuit.
