ECN Forum Forums Code Related Discussion NEC & other Code issues Multiwire Branch Circuit

I believe that under the 2002 NEC a tie handle was not required for a multi-branch circuit. However in the 2005, I believe that it is going to change and a tie handle will now be required. Our state still follows the 2002 NEC for now.

That multi wire branch circuit is only one circuit. For it to be two circuits you would have to run it with separate neutrals. Since the building will be served by only one branch circuit a grounding electrode system is not required.

Since the garage is on residential property you are allowed to use snap switches as the building disconnecting means. I favor the DPST approach but that is certainly not required.

Caper the 2005 just removed the "dwelling unit" language. The "same yoke" stayed the same. Now a commercial MW, landing on the same yoke needs a handle tie. If it splits out it doesn't.

I don't think so. If you look at the defination of a Branch circuit in Article 100 it states. The circuit conductors between the final overcurrent device protecting the circuit and the outlets.

I would tell the contractor it was ok to split the neutral on the two branch circuits but I would suggest he take a look at the requirements of 250.32.
