Permanently connected dishwasher and garbage disposer with switch on 14/3 and separate 15 amp breakers. Does this require handle ties?
 
Re: multiwire branch-circuit

No, see 210.4 (B)

Roger that would be a yes if.... a duplex recep.split tab was used then it would be the same yoke for 2 circuits(Oh and yes for this they would have to be cord connected.)And a 2 pole is needed
 
Re: multiwire branch-circuit

As i am trying to understand this , there would be a shared neutral involved here and a doulble pole breaker would be required or handle ties if using the 2 single pole 15 amp breakers .

More asking a question than answering one on my part.

Hi John. This is a very misapplied code section, so can see whre your coming from with your question.

The 2-pole or handle tied breaker would only apply if the two hots are on a single yoke (device strap), such as a split, or "half-hot" receptacle. An example would be trying to keep lighting on a circuit and power on a circuit, so you switch half of a receptacle for the lamp and put it on the lighting circuit, and the other half you keep on the receptacle circuit. This would require a handle tie or a 2-pole. Make sense?
 
Re: multiwire branch-circuit

Hello John, the handle ties or double pole breaker would only be necessary if both circuits landed on one yoke.

Too funny. Roger and I are sending each other private messages at the same time, then we find out out we're replying to the same post at the same time (again). :)

Sometimes putting things in a proper perspective is challenging to those from a lesser lattitude.
His words are well placed and very informatived for those who want to listen and learn , for the ones who are in conflict .......oh well, let them carry on and be source of entertainment.

As has been said this would only be true if both circuits land on one device.

Other than that two single pole breakers can be used and they do not even have to be beside each other, just separate phases.

Look in article 100 for the definition of multiwire branch circuits.

John and John, thanks for the kind words.
