Can you use anything besides RMC from the meter outside, to the panel inside? I couldn't find anything saying it HAD to be RMC only.
Thank you.
Thank you.

There are local codes that may specify rigid only but the code does not. See 230.43

That is a POCO ruling.. some places have SE cable running out of the bottom of the MP and exposed till it goes through hole into the basement.. 
hmy:
We use either PVC or EMT.. and a sill plate..

Back in 1974 my boss was RMC all the way on service changes even at that time he could have used se cable but to him "NO WAY".
In fact i did the same thing till 2003 when a stick of 2" RMC went from $14 to $62 over night so i do them all in PVC now.
But RMC is not required by the NEC otherwise you would never see an SE CABLE SERVICE.

From a single meter only to the main—where the meter is mounted on the structure-we cannot use SE cable. We have to use conduit. And this conduit cannot be ran inside the structure over 15 feet

Next question is:
Can you use FMC or LFMC? The panel is about 5 feet, diagonally, from the meter and one of those would work great. The other options wouldn't make the bends. Already moving the panel, but the meter is above a window opening in the basement (old house), so anything rigid isn't working. It would be ran inside the wall to get to the panel or through the floor joist.
Thanks

I was posting these questions from my phone at work, so I didn't have my code book with me. Now I feel like I should have looked before posting the last question.:huh:
Thanks for all the input and help.

Before the market took a dive, I did mostly commercial and some industrial. :roll:A friend of mine is buying a house and remodeling it before he moves in. He asks me questions now and again, and I help where I can.
Now I crush rock for a living. Hence, the name.

You're not required to look it up before asking a basic question. If you were doing homework questions then we would like you to try and find the answer first on your own. Feel free to ask away.

It's funny that people think that just because you're an electrician, they think you know everything about it.
I realize residential is different, like commercial and industrial are different.
Going to be taking my contractors test later this year and will be using Mike Holt to help me study with some of his tools.
Thanks for the post Jumper. I have a code book, just not at work with me. I love being an electrician, but have to feed the family and unemployment don't cut it.
Sorry if this thread went on a tangent, but now ya know where I'm coming from. Sorta.

My suggestion is to go to one of the classes they have prior to the exams - even if not the class for the test session you are planning to take. You do not have to be scheduled to take a test to attend the class. It's been a few years since I tested now but they did cover almost everything you may find on a test. It also counts for CEU's for renewing your license so you get some of that out of the way at same time.
And you did not go far enough topic to have committed anything on this site. For starters it was at least electrical talk for the most part - maybe rock crushing is off topic but we have spent 20-30 posts before discussing about how diesel engines work when the OP had nothing to do with diesel engines.:happyyes:

Please note the OP says "from the meter..."
This sounds like an installation where there will not be any outside disconnecting means - something that is very likely ammended by the local code.
In a similar manner, it's likely the fire code will want an outside disconnect.
The next step in this discussion will be 'what does the NEC mean by 'nearest' the point of service entry?'
I really don't have much concern over 6" of SER going through the wall to a main disconnect on the other side. I do have an issue with unprotected SER going up the wall, across the ceiling, and down the wall to a panel with six breakers in it.
If he's redoing the service, IMO, he needs to have a disconnect at the meter. Code finesse aside, it's simply stupid to not be able to turn things off without pulling the meter.
