Multi-wire circuit questions

Couple of questions about the requirement for double pole breaker and pigtailed neutrals:

1. Is a double pole breaker always required for a multiwire circuit? Could be wrong but I thought I saw a response awhile back that said that the requirement applies when the two hot wires run to the same device, but not when they do not. I have a multiwire circuit where the two hots power two separate outdoor circuits, and do not run to the same device. It currently has a double pole breaker and I have no reason to change it, but was just wondering if the requirement is "absolute."

2. Also, are pigtailed neutrals also always required for a multiwire circuit or are there any circumstances where they are not? In the circuit described above, I do have an "unpigtailed" neutral that I can fix if required.

Thanks

It is sometimes, but not always, required. But it is always a good idea.

True. In technical jargon, substitute the word "yoke" for "device", since a duplex receptacle is really two devices on one yoke.

Also, are pigtailed neutrals also always required for a multiwire circuit or are there any circumstances where they are not? In the circuit described above, I do have an "unpigtailed" neutral that I can fix if required
Yes, pigtailed neutrals are always required when the neutral is serving two hots.
