Most of the panels here are located inside of the building and the meter is one the outside well above the height of a car bumper. Now if they're both on the outside that a different story.;)

Oh yeah, How I quickly forgot my roots with the basement below grade in the North. Here you never see a basement totally underground. Usually it is open on one side if there is a basement at all.

Describes my on house service exactly, when I bought the house the sill plate covering the SE had already been broken from in all likelihood a snow plow. Luckily the SE was undamaged.

So what do you do about the vertical riser from a meter socket?

Do you bond the top end of that?

That sounds like a good point, but there isn't an enclosure on the end where there is a weatherhead.

Lets says all you guy's bond the meter base side and use a plastic bushing on the panel side.The conduit takes a hit, breaks apart, loosens the locknuts and the wire energizes the broken conduit with just the plastic bushing on it.The service panel is bonded via the screw, but the conduit now hasn't an effective path because the bonding bushing wasn't installed.This is why i think both sides should have the bonding bushing or grounding locknuts.

But not allowed to rely on locknuts alone.

I agree that is why you have the bonding bushing that was talk about in the earlier posts. One bonding bushing not two and no ground wire between the enclosure.

I think you are missing the point about the panels being bonded. The neutral (grounded conductor) is providing protection for both enclosure. It is attached to the metal of the meter and the panel on the other end.

That is bonded through contact with the metal hub that is securely screwed in to the meter base.
If your riser is coming out of a metal gutter and you are useing a Myers Hub. Then you would have to use a bonding bushing on the metal riser.
Because of the rubber insulator.

Exactly, but no one bonds the top end which was the point I was trying to make, a service raceway is only required to be bonded once.:smile:

That makes no deference as all the enclosures we are talking about are already bonded, the code only requires each item to be bonded once.

I have placed bonding bushings on both ends but I did not have to.
 
I can't believe nobody liked my broken pipe scenerio

. I thought that was a winner.I guess i'll take my barrel of cheese balls and go sulk.

If a man must sulk, I can't think of a better way to do it but with a barrel of cheese balls. Myself, I'm sorta hooked on Grandma Utz's, but I'm not sulking at the moment.

Your broken pipe idea did open the door for more discussion, so perk up!
 
Al Dagys,
Your scenario is very much like Memphis, TN.
We must Bond from the Meter Neutral Bar to the Panel Neutral Bar, continous, with #4. This exactly parallels the Service Neutral which feeds from the meter to the panel.

What purpose is this conductor supposed to serve? :-?
Is the neutral at risk of disappearing?
 
JohnJo,

MH wrote back, once upon a time, that it was redundant.
But, the local Code and AHJ have the final say.

The way I see it is that
if the Neutral is in risk of disappearing,
then also the Bond is in the same risk of disappearing!

I just wonder what they think it will do that the neutral won't.
