Good afternoon. We are having to install some handle ties for some existing panels. Section 240.15.B.1 states "Individual single pole circuit breakers with identified handle ties shall be permitted as the protection for each ungrounded conductor of multiwire branch circuits. " I dont see where it says a 2 pole is permissible. However I have seen many drawings showing 2 pole breakers as acceptable. If I have 2ea branch circuits @120vac sharing a neutral, can they be protected on a 2 pole breaker versus 2 singles with handle ties? I have never used them but have seen this done. I dont see in the NEC where it is permissible.
