MWBC

[dvcraven052256]

I was thinking of providing a neutral for each 120V branch circuit in lieu handle ties or 2-pole breakers. I am not sure which method best in terms of cost. Your thought are most welcome.

Thank you

MWBCs save on material and labor.

Handle ties are cheap. Running a 4th conductor will be more expensive.

Yes I understand the concept. But MWBR require to disconnect all ungrounded conductors via handle ties or 2-pole breaker. I was thinking if I ran a neutral for each circuit then it would no long be a MWBC.

Correct, it would not be a MWBC.

What is the installation method? NM cable, MC cable, wire in conduit?

Can you price it both ways?

Not many places (in residential anyways) to use a MWBC unless you buy a 2-pole AFCI or use two AFCI, with a handle tie, that don't have the GF portion in them.

Most times; but there are breakers brands that I can't get a handle tie for even though the mfg. list them, or they don't even list them for a particular breaker brand.

MWBCs also are more efficient in terms of waste energy, especially for heavier duty circuits like kitchens or single phase air conditioners.
