Old Work Common Neutral AFCI Problems

[implant]

I am installing a new Service in a 35 year old home. The majority of the branch circuits are 3 wire circuits utilizing a common neutral, Example: Circuit 1 for the bedroom, 2 for the kitchen. What are the available solutions to protect the bedroom areas on these circuits, and how does the NEC deal with this application?

Re: Old Work Common Neutral AFCI Problems

The NEC is not retro-active and therefore does not require the AFCI's to be installed. I have heard there are some states that are considering, or already have, changed that to be required with a service change out. Does your state have any amendments to section 210.12?

Implant Look at Cutler Hammer, They manufacture AFCI's now that have UL listing for many brands of service equipment even Square D. QO's They are called there Classified Replacement Circuit Breakers line. And they have two-pole units without the common trip to allow multi-wire circuits.
Here is there web site for these breakers: Just do a search from there for: Classified Replacement Circuit Breakers

A quote from the web site:

Eaton's new Cutler-Hammer Replacement Circuit Breakers are the key to easy installation and streamlined inventory. CL and CHQ replacement breakers erase the need to carry virtually all manufacturers' circuit breakers. more...
