Re: distance for SECs inside the building line
If the WA in your name is for Washington State, then your answer is here:
http://lni.wa.gov/TradesLicensing/Rules/files/electrical/wac29646Bjuly2005.pdf
See section 070 under 296-46B-230. If you do electrical work in Washington, you really need to read the WAC. Keeping a bookmark to the LNI website would be a good idea, as they link to the latest WAC.

Re: distance for SECs inside the building line
Good point, Mark.
Tim, if I understand your situation, you are about to take the Administrator exam. I suggest that if this subject comes up, you read the question very carefully. Be sure you understand whether they are asking about the NEC rule (no distance is specified) or the WAC rule (15 foot limit).
Also, be careful about whether they are talking about running the conductors into the building under the slab. So long as the conductors are below 2 inches of concrete, they are not yet "in the building." The 15 foot restriction begins when the conductors pop up from below the slab, even if they have travelled 200 feet under the concrete before they got to that point.

Re: distance for SECs inside the building line
Tim:
Make sure you have the current WAC rules.
You'll need the version effective June 30th 2005 and the admendment that goes into effect Nov 25th.
You need both. You can print them from the internet and take into the test with you.
Here is what I say in my classes for Washington State:
You can't know the NEC without knowing the WAC and vise versa....
Washington State does a great job of correcting the NEC mistakes for its rules.

Re: distance for SECs inside the building line
Wow - 15 FEET ?
Here in Maryland I'm feeling lucky if they will approve 5 Feet ! I could have saved the customer over $600.00 on the last addition I did if the AHJ would have approved 8 Feet of unfused SE inside.

Re: distance for SECs inside the building line
really for 15 feet for unfused conductors for inside the resdential area is too much [ i am in state of wisconsin we are restricted to either 6 or 8 feet i useally go 2 meter {metric mesurement} anymore than that have to be fused for safety reason unless it is encasted in cement with pvc pipe.
i am not sure what other state will say about this for unfused conductors espcally in resdentinal area that part i feel it will related with NEC and state codes
Merci, Marc

See 230.6

You could run PVC and either brick it in or encase it in concrete. If you do that you can go as far as you want. It might be cheaper than the electric equipment.

" You could run PVC and either brick it in or encase it in concrete.."
Not an option , Se running in basement, overhead in the joist's for the first floor. Had no choice but to set a 200 amp enclosed breaker then refeed the existing service making it a sub-panel

Re: distance for SECs inside the building line
Members of Forum,
I was just looking at "Versaroc" cement board,it is 71% Portland cement,10% fibers,etc.,also it is non-combustable.
So, keeping in line with this thread,I'm wondering if this product was built up to two inches around SE conductors entering the building would they be considered "outside". Just testing the "Edge".

Is cement and concrete the same thing?
Would they have the same fire rating?

Re: distance for SECs inside the building line
Depending on your location,the building codes may require only so many feet. Here it's 5ft.
If the structure makes this a problem the AJH will work with you.

Re: distance for SECs inside the building line
What we really need is for someone to manufacture a conduit that has a 2" concrete covering. Lift optional.

Re: distance for SECs inside the building line
Wow, what great replies all up, thanks so much.
Further digging today, found the thing.
No, it's not in the NEC, yes it's in our Washington Administrative Code (which I know a lot better tonight!)
No, it doesn't mention unfused SE conductors but 15ft for service raceway inside the building, which of course for all purposes amounts to the same thing. Interesting other states are envious/alarmed we allow that far inside. I thought WA had a reputation for being somewhat restrictive.
Thanks charlieb for the slab info. Good to know.
Thanks suemarkp, yes I am on the WA L&I listserv, do have the latest WAC, just needed to read it better.
Thanks Tom Baker, is there website/info for your classes in WA?

Re: distance for SECs inside the building line
I know there is, and I know how to get in touch with him. However, as we do not permit advertising on the Forum, you will have to send Tom a Private Message (PM) to get that information. But first, you will have to enable PMs by making a change to your profile. There is an FAQ item that talks about PMs.
