Hi, I am looking for the requirements for extensions to existing branch circuits. These are 2 wire branch circuits(no ground). I have looked in article 210 and didn't see anything on this. Can someone point me in the right direction? Thanks
You cannot extend 2 wire circuis without adding an egc. Any extension of a circuit must meet todays code.Hi, I am looking for the requirements for extensions to existing branch circuits.

I was trying to do what Dennis said. I thought It was acceptable to put a GFCI receptacle where the old and new join and are extended and not use the ground wire on the new part of the extension.
You might look at 250.130(C) and see if that is applicable to your situation.
I think you would be better of running a new circuit,
and you will make more money that way:grin:
I would ask the AHJ but IMO, that is not really an extension of the circuit. You are not adding any outlets, etc. Also BX is a ground so you are good. Some AHJ's will make you add AFCI-- I think that is BS.what about extending 2 wire branch circuits when changing a panel ?only asking cause I am doing a service next week and alot of the bx must be extended and I was going to box them in a can and use romex to extend

Is i illegal in the 2008 mass Electrical code you cannot replace two prong outlets with GFCI's we can only install new two prong outlets.
Leo, can you find that in the MA amendments?
I can't.
this is intersting:-?
On page 6 of MA amendments 250.130(C) Deleate this subsection,,,that is how it appears in the 2008 and the 2005 ,,I am missing my 2002 and 1999. in the 1996 the wording can be found on page 10 in 250-50a
The ma amenments have change over the years on this subject and in the last two codes they just deleate 250.130(C) so now i am so not sure what the mass code is trying tell us .I know that in the past mass code they wanted us to replace two prong outlets with new two prong outlets when no ground is available.
so if you can find that in your old code books that would help
Leo said:Is i illegal in the 2008 mass Electrical code you cannot replace two prong outlets with GFCI's we can only install new two prong outlets.
Did you read posts #11 & #12. IMO, you should not have an issue but I am not the inspector and he is the only one that can tell you what he commands.So I shouldn't have a problem extending the bx with new romex
Yes, the change in 250.130(C) is there but that section has nothing at all to do with this.
We can replace two prong outlets with GFCI's per the rules in 406.3(D) which are unchanged in MA.
I agree if you have BX just install a 10/32 in the box and your good:grin:
And unless your running a new circuit you don't need an AFCI.

Interlocked Type AC cable is manufactured with an internal bonding strip that is in direct contact with the interlocked metal armor. The combination of the bonding strip and the interlocked metal armor makes the cable suitable as an effective ground-fault current path [320.108].
