This is a great video and needs to be sent to all the leads starting out. I've seen this so many times.

@33electric33 Месяц назад

I agree. Very common, but the code does specify it covers single point grounding systems. Many dont understand it.

@KevinBrown-vm9zg 2 месяца назад

You stated before correctly before this point and elsewhere the minimum size grounding conductor, but at 2:51 and 8:00 you state "maximum" size.

Great video, we had this same situation on a project! Thank you for posting

i have 6 volts AC from Neutral to Ground ( ALL electrical outlets have this ) . the ground wires in the breaker panel are all tied to the breaker box via the ground bus, however the breaker box is NOT tied to the ground rod , while the Neutral is tied to the ground rod . thus neutral and ground wires are NOT tied( bonded ) together, however , the breaker panel appears to have been wired correctly . Neutral to Ground bonding is missing update june 28 , 2024 i tightened the Green Bonding Screw . return neutral bus bar now fully connects to the metal breaker box. 0 volts on ground now , perfect.

Excellent video.

Very helpful thank you. Was unsure what did and did not need bonding.

Glad it worked out for you. Stay safe.

It looked like there were mixed brands of breakers in that Eaton sub panel

@33electric33 25 дней назад

@larrymazer Probably. I didnt install the panel. Just fixing inspection issues and safety issues on that one.

That was part of the goal in making the video! LOL Glad it helped.

Maybe you can shed some light for me on setting up the ground connect from the meter can to the cutoff switch? The power company wired the meter with the usual two hots and neutral. Then they wired the meter can to ground and on their installed ground rod. I have to install the disconnect. They require ground bushing to do that. My presumption is that the bushing should be inside the cutoff box on the service side of the switch. Where to I connect the grounding wires to? At a guess, I should attach the ground inside the meter can and then open a section of insulation for the ground bushing to clamp on then, from the bushing continue the ground wire to bus inside of the disconnect switch. Is the disconnect now the main panel? Do I need to continue ground from the disconnect into the conduit and the circuit panel which is now a sub-panel? I still have to install a separate ground rod for the sub-panel so I am not understanding why I would need a ground between the main and sub-panel. It's only a 24' run, underground, from the disconnect to the sub-panel so the cost not such a big deal compare the cost of the cutoff switch. Any links or recommendations you may have to offer? Thanks, enjoyed the video.

Grounding in the meter can depends on the local power company codes and rules. Some require it, where I work they do not want any new work to have grounding in the meter, or uninsulated wires. The single point ground connection where everything bonds together is either at a disconnect if there is one or the electrical panel if there is no disconnect. If you have metal conduit to the meter can then you do use bond bushing to ground to the meter can ground terminal.

I have a question. At 9:20 into the video I see that in you have connected one of the hot wires coming from the bottom of the meter to the neutral block in addition to the neutral wire coming from the meter. Shouldn’t it be connected to the empty terminal feeding the main breaker? I can’t see how you could have 240 in the breaker panel.

@33electric33 День назад

@jruggle @jruggle Sir, if you don't understand the basics of Alternating Current set up, then it's probably best to leave it to a professional. Anybody who just knows the basics knows that's the neutral terminal. The wire just wasn't properly marked white by the previous installer. The hot wire is still hanging out, you just can't see it in the video.

This is one they keep getting wrong in the field... Wall of shame for them this week.

@Doomm3x Месяц назад

How many ground rods you need to install for 100 amp service?

@33electric33 Месяц назад

A minimum of 1 electrode is required. If it has a resistance to earth of 25ohms or less then you do not need a supplemental electrode. If you do need 2nd electrode it must be 6ft or more apart from 1st electrode. So its about the ohms to meet the code, not how many. Good question

@Doomm3x Месяц назад

Thank you.

@33electric33 Месяц назад

@@Doomm3x Also, something else to note is that if a permit is required in your jurisdiction and the service may get an inspection by AHJ, that inspector may make you install 2 ground rods no matter what. It can depend on the inspector as well since they have the authority, so when I do some service installs I just put 2 either way.
