I believe that the intent of 230.6(5) is that the service conductors are run in a complete conduit system and not just sleeved, but it doesn't actually say that. 230.92 will require that this conduit be bonded.

I agree with 230.6 when it comes to determining what is allowed inside the building makes this questionable if not in RMC or IMC or encased in 2" of concrete, but what about a metal sleeve (not a raceway) for physical protection of SE cable?

I think you meant 250.92 on the second part, but again it doesn't mention short sections for physical protection purposes of a cable that is otherwise not required to be in a raceway.

Quite frankly if the extra physical protection is needed I would more likely just run raceway the entire run but I guess it would be acceptable to sleeve it in places subject to higher level of abuse.
 
Thanks. I guess to be safe, moving meter and running galvanized up is the way to go. Homeowner wants to do all this just to leave it a 100a service. It really is blowing my mind not to upgrade to 200a but I guess not everyone's pockets are the same. Does anyone know if it's permissible to use 1" gal for riser or is 2" gal a minimum for service masts?

You will have to see if the PoCo will allow 1", not following their rules will not end well.

Is your conduit going to support the service drop or are you leaving the wood mast for that purpose?

Many POCO's don't want anything smaller then 2" though NEC only says it must be physically strong enough (not sure exact wordage off top of my head).
 
Thanks guys. Yea I would leave the wood mast if I did it with 1", but probably going to just run the 2" gal though. As for everything else, it looks like the meter is going to be moved directly under the mast to avoid any doubt. Happy Thanksgiving guys, thanks again for all the help!!

You really should contact your POCO. I deal with several in my area and they all require 2-1/2" Rigid if penetrating the roof. It would save you some headaches if you ask before installing it, especially if what you planned on installing was the wrong size.

Yeah, did a 100A service in SMUD (Sacramento Municipal Utility District) territory & did not have their specs until got to the job, PG&E allowed 1 1/4" for the mast, SMUD required 1 1/2" min so had to scramble on a Saturday job. :D The job was to replace a existing Zinsco panel in Rio Linda CA. :lol:

But it sounds like he is still using the wood mast to support the service drop.

I looked at the pictures again, and also noticed there is phone/CATV drops attached as well, if this were a typical RMC through the roof service mast, it couldn't support those other drops. I also noticed the drop passes over more then just the overhang on the side we are looking at it from. Not sure how much total roof it passes over or what the slope of the roof is, but may need some additional height because of this.

It wouldn't matter here what was on the roof for support, if the mast penetrates the roof we have to use what is specd, which is 2-1/2" in my case.

The phone/cable stuff isn't allowed on our masts either but I sure find enough of it when I've had to upsize a service or replace a broken mast.
I've been tempted to just cut the lines instead of taking their clamps loose!:happyyes:
