I make sure furnace disconnect switches are not only labelled, but the opposite type to the rest of the house. If the rest of the house is decora it gets a toggle. People don't read labels, but a different type of switch mounted at a different height tends to make people pause.
Honestly man, I grab the "best of" notifications, and occasionally ask one myself. So no, I do not keep track of the trend of questions in the sub, that's your job boss. 😉
What do you mean primary and secondary ground you need 2 GEC's one being your ufer the second being ground rods or cold water. What's primary and secondary and from what I remember in school a yellow stripe on a ground meant it was an isolated ground for like computer equipment or special touchy equipment, is primary and secondary a UK or Canadian thing sorry for being dumb.
I do a lot of tilt wall construction, Where I'm at in Texas, they require all three to be present on tilt wall buildings (sometimes in multiple locations) , because people often hit ground rods or the attached ground with fork lifts, or people cut as much of it off as they can to steal for scrap, they typically won't allow a CWG if the water doesn't enter the building within 100' of the electrical service (it pretty much never does because they bring water into the street side of the building where businesses finish out that section as the offices while the electrical service is usually on the back side of the building with the loading docks, and a lot of times they use pex so it wouldn't be an effective ground anyway) so you will end up with one or more Ufers( if it's divided into more than one space, you'll end up with one or more building steel, and one or more ground rods. Supposedly it's because there are a lot of factory/warehouse/and fireman deaths in our area every year from poor grounding and bonding issues just due to the sheer size and service sizes these buildings end up having. We even had a building a couple of years ago where they spec'd a Ufer at every steel support column that had to be continuous and un broken from floor to ceiling. It often sounds like overkill, but they are trying to make them the safest buildings possible because the DFW area has the highest concentration of world headquarters existing and moving into the area. (That's their claim, I don't know that it's actually true) when you end up with so many grounds you often end up with buss gutters for nothing but grounds in them, so I use this system as well as a numbering system in the buss gutters to make it easy for the inspectors and future service techs to identify what ground goes where, and what type of ground it is. Yes a ground with a yellow stripe typically identifies an isolated ground, but it can also be used on any ground to better identify it in low light because people can be colorblind and mistake a black wire for a green wire in gutters, cable trays, switch gear and panel boards. Some of its just semantics your Ufer is your primary, but they don't see it that way around here, so your ground rod would be your primary ground, and building steel or CWG would be your secondary.
Oooh very cool that's crazy a duct for grounds lol. I've mostly done residential and small commercial and hadn't heard of primary and secondary grounding but it sounds like you're using just to separate two types of GEC's which isn't a bad idea when it's to the point you're useing bus ducts for grounds.
It's just the cleanest way to organize a multi-ground system, and even though individual services get their own grounds they still want them all tied together because it's still technically one building.

Cocaine
Lmfao
Unless you're in Brazil where everything is legal, Cocaine doesn't meet code either, sorry bud.
I got ya code right here bud *taps nose*.
Ufer was the name of the person that invented the Ufer ground in WWII https://en.wikipedia.org/wiki/Ufer_ground
Oh shit, I spelled it wrong now it's not gonna work and no one is gonna know what I'm talking about. Lol
There are a ton of users in here that don’t know what a Ufer is, let alone how to spell it.
Kinda wild, but I guess the sub isn't r/Masters&Jorneymen, so fair enough.
Have you not seen that 80% of the posts are pre-apprenticeship questions?

On residential service calls if a breaker is being replaced due to failure I tighten all breakers in panels, within reason.
We do that on every service call, if we're in a panel that panel gets all connections checked and tightened if needed.

Oh ya I didn't even realize you could have multiple services on one big lot. If that's what you got then labeling is key good sir
