ECN Forum Forums Code Related Discussion NEC & other Code issues Service raceway, or not?

Let me at it again.
Both enclosures are bonded to the neutral, and therefore, bonded together. You can't get a lower impedance path than that. The nipple now needs to be bonded to only one of the (bonded) enclosures, so in the (unlikely?) event of a ground fault inside the nipple, a low impedance path is encountered, thereby burning clear, or operating the primary fuses.

Hmmmm, unlikely ??? You guys haven't driven service trucks long enough. Bond an overhead service enclosure ??? We use weatherheads which are bonded by being threaded, no locknuts are relied on, or even used, at the weatherhead end, don't know what you guys use where you are.

Is the practical concern for the travel and/or parrallel fault path or it's overall connectability?

this IS making pvc look good...

George,
Are you telling us that you bond the grounded conductor to the weatherhead????

would 250-142 allow this?

Sparky,
It is permitted by 250-142, it's just that I have never seen it done. My point is that George is telling us that both ends of a service raceway must be bonded. I am asking how he bonds both ends of the riser. If he doesn't bond both ends of a riser, then why are both ends of a raceway between 2 service enclosures required to be bonded? I still don't see any requirement to bond both ends of any service raceway in the NEC. I don't see any problems bonding both ends and it is probably a good practice, but it just isn't required by the code.

Maybe someone is confusing service raceway bonding with bonding both ends of a GEC raceway. This is required to minimize the choking effect caused by the reactance of the single conductor enclosed by metallic raceways.

OK guys one moreand I think we've worn this puppy out. Yes, you can bond the service race way to the grounded conductor, it is is small enough, it is even practical.

offset nipples aside, You're telling me,that if the service conduit in this question were 200' long, 2" rigid, you feel the code says one bond bushing on one end, and locknuts on the other are sufficient ?

Same thing, now were just debating lengths.

Yes, George, that is exactaly what I'm telling you the code says.

>if the service conduit in this question were 200' long, 2" rigid, you feel the code says one bond bushing on one end, and locknuts on the other are sufficient?
I see your point. In that case, I personally would bond at the end nearer to the service.

Secondly, if I thought that it might have to dissipate lightning or radio frequencies, I would bond at both ends.
