I have a situation where the meter for a service in on the utility's pole and the SE conductors will be buried in a trench to the single family residence. Can the SE conductors enter the house below grade? (depth compliant with Table 300.5) The basement through 2nd floor wall is an insulated concrete form wall. A piece of Schedule 80 PVC (the SE raceway) will be placed in the wall before the concrete is poured. The PVC will be sealed as required by 300.5 (G). Is there a violation that I'm not seeing?

Where is the disconnect located or will be located?

Sounds like a plan, but I personally prefer buried conduit rather than direct buried conductors.

Yup, I had to do that once where the owner of the house did not want the meter socket or any conduits on his house.

You can not bring type USE into the building.

I agree. Most USE cables cannot be brought into the building. Art. 338.10

However, if you pay a little extra for the cable, USE/XHHW or some other dual rated cable may be used inside.iwire said:

I always wondered about this. If art. 338.10 says use must terminate outside then why are we allowed to terminate dual rated inside. Does the code give exception to dual rated somewhere?

As long as it says XHHW on it .... it is and can be used as such.
On my solar projects we use a lot of UES-2/RHW-2, this allows us to run exposed in the array and continue into the building if we want.

Help me out. What can you run this exposed? Just because the voltage is less than 50?iwire said:

I just ignore the rules and go for it. :wink:
Don't have my book at hand right now but in 690 there is a section that allows type USE to be run under the rules for UF cable as long as it's 'within the array'.
It is a tough to overcome years of habits, when I went for my inspection I brought print outs from the IAEI magazine that went over the details in case the inspector questioned it ......... he did then got over it.
Use
Use
I disagree, look at the UL white book under service entrance cable(TYLZ). "Types USE and USE-2 are not suitable for use in premisis or aboveground except to terminate at the service equipment or metering equipment."
Also, we do not install conduits like this because they make a good drain pipe into the house.

Your looking at an old book and take a look at 2008 NEC 338.12(B).
You can not bring USE inside a building unless of course it is dual rated.:smile:

Al, several years ago, I contacted Don Nissan, a UL Representative until he retired a few years ago, to ask about the use of USE cable. He told me that it has always been intended to prohibit the use of USE inside any structure. However, it has always been permitted to terminate on the outside of a building in the metering or service equipment. :smile:al said:

You aren't required to even have a disconnect on the pole below the meter unless local codes require it.
