Anyone want to take a shot at why #6 to attach antenna ground to breaker?

Piedmont

Thanks, I ended up using 2 grouding rods and the acorns to attach the wire (and NEC only allows 1 wire per acorn). I don't know if this makes a difference I have a Square D panel, I don't think the holes of the neutral bar are big enough to handle #6. Will attempt when I get home. My panel looks like picture (that's not mine) which has #6 coming in connecting between the leads I didn't see an easy spot for another but, if you can fit #6 in the neutral bus bar holes I'll be happy!

The inside bar of the right hand two in a QO panel has several holes where your #6 will fit. Look for the larger screws.

Piedmont,

It looks like from your picture you need to shift a 14AWG groun or neutral to a lug with a small hole. That will free a space for your wire.

Andy, that's not his panel. It's just an example.

At the risk of hijacking, does anyone else notice six single pole AFCI breakers with "black/red/black/red/black/red" pattern???

Yep I see that. Interesting.....

'Gazillion rods' and 'anaconda-sized' are what you call it, literary exaggeration. And yes, bearing full brunt of a direct lightning strike (and protecting yourself from it) is the domain of insurance companies, not electricians. However, during storms, air is by and large ionized, and minor discharges can occur on a regular basis. My argument is, if your electricals are not gonna blow out on 2 rods connected by a #6, they should be fine with a single rod system (assuming no antenna) as well.

I'll go you one better...Have a good bond either to your water or to your foundation and never drive a ground rod again, 'cause they are by and large, worthless.

I spy 3 14/3s top right.

I think the panel picture posted is one that has violations and was probably discussed most likely on another forum somewhere. Did anyone notice the type of connectors that are used in top of the panel and the number of cables coming thru them?

Andy why do you make statements like this are you trying to drive me insane.....

Andy in ATL

A properly bonded water pipe is going to have a lower resistance than a rod. A properly bonded foundation is going to have lower resistance than the pipe or the rod. The rod is silly if you have the other two. I know it is code, Stubbie. Ive shed alot of sweat driving rods. Always gotta be two rods if one is more than 25 ohms. But if two are 200 ohms or 2000 ohms, what the hell, it will be ok.


Stubbie, I only drive rods because they are required by code. Other than that, they are worthless. I also educate my contractors on the need for a code compliant piece of rebar in the footer that I can attach to. That is all the ground any dwelling unit will ever need. Don't mean to drive you crazy. I like you Stubbie. Educate me on the value of a rod.

Andy

Edit to add: I forgot the honker big ground at the transformer.

Does a sub-panel need two grounds or is the main panel enough?

Speedy Petey

This question is unanswerable as asked.

Because you stated either a water pipe bond or a rebar bond in the footing/foundation then no rods.... but I see what you meant now so i will sleep well.
But I still don't get the statement that rods are worthless. Why do you always ask others to prove your statements wrong can you not back up what you say with your own facts??

If I have all three electrodes ...water pipe, ufer, and two driven rods ... are you saying that driving the rods was a waste of time?? And if so... why....you teach me something...you made the statement not I.

Andy in ATL

Let's say I have a water ground at a half an ohm. My ufer ground is at a tenth of an ohm. I reached the magical number of 25 ohms with my two ground rods. They are not worthless...they will divert some of the voltage. Not much though. Yup, worthless.

No comment. You sure dance to a different tune but hey that Honker sees something in you.....
