Re: SER connector
Okay, Pierre. You twisted my arm. I'm gonna start using IGS cable on the load side of the meter.
Seriously, the goal here is to get something that will fit in a 2x4 framed wall. That is hard to attain using SE cable with the wiring methods and fitting currently available to us. Darned impossible with SER. I guess they do make 90* connectors for type MC cable. That would be a decent option.

Re: SER connector
Do they make 1/3 CU NM?
They're not service conductors.

Re: SER connector
NM's not on the list, but MC is. They certainly make MC in the gauges we'd need for a service. All kidding aside, I'm not giving it some thought for these oddball installations, since they have a 90* connector available. I'm now pondering what special bonding efforts I'd need to attend to in that case.Originally posted by georgestolz:

Hmmmm... that might throw a hitch into my grand plan. It does sort of have a removable cover. Why would you ever need to remove it, though? You can't replace the conductors in MC cable like you could do with an LB and a raceway system. There's no viable reason why that fitting would ever require service. If we we're talking Greenfield, and not MC, I'd say that it can't be buried. If that cable ever needed replaced, you'd have to open up the wall anyhow. I say it can be buried for now...

Re: SER connector
Nice to finally make your aquaintance, Marc.
No, I'm saying Pierre's list doesn't apply, there's a main breaker outside. Or are we talking in circles?

Re: SER connector
I was able to determine that MC cable with (3)3/0 and one #4 does have an overall diameter of 1.600 inches. The 90* MC connector for that cable diameter (from Arlington) would stick out of the back of the meter main 2.300 inches. That would fit nicely in a 2x4 wall.

Re: SER connector
3/0 requires minimum of 4 inches of bending radius inside the panel as per 312.6. Selecting how one enters the enclosure is very important.

Re: SER connector
I imagine the 1/2" or so of OSB + Siding might throw a wrench in the works. Try it out, let me know how it goes.
I need to tell that side of my brain to stop giggling, grown-up stuff is going on.

Re: SER connector
Is not the bending radius of SE cable not to exceed five times the diameter of the cable measured along the inter curve?
Would this be the bending space at terminals?

Re: SER connector
When conductors enter an enclosure, you will need to pay particular attention to 312.6(A) & (B).
Also read 312.6 Deflection of Conductors.
Some of the other bending radius that you have mentioned could be for wire located ouside of enclosures, such as bending around corners.

Re: SER connector
I'm just playing devil's advocate. In truth, there are three sizes of MC cable right angle fitting that will work for this O.D. size of MC. I picked the smallest in my example. I'd have to jump up a size or two to accomodate for the thickness of the sheathing and siding anyhow. That would take care of the bending radius issue handily.
I agree. Are you trying to indicate that an MC cable fitting exists for a certain size of MC cable that can't be used in a compliant manner? I don't think you are.
