2 breakers in same box or split outlet?

I'm installing a new washer and dryer and I'd like dedicated circuits for each. If I'm using a tie down bar, can I put outlets from two different breakers in the same box?

One more. Same as above, and can I put them on a split receptacle (lower powered by one circuit, upper by another)?

Thanks

Either way will be okay but why? Usually they can both be on the same breaker.

Assuming it is a gas dryer.

But why
Quote from Ray above. Why? It's good you're tying breakers. But as a courtesy/warning to others, I would still take a permanent marker and mark backside of face plate "warning, this box contains two circuits".

I would also use 12-3 to make it easier to identify.

If you are using a multi-wire branch circuit the handles need to be tied or a two pole breaker used.

If you have two circuits on the same yoke the breaker handles must be tied (or use 2 pole breaker) regardless of whether it is a multiwire branch circuit or not.

I think Ray may have been asking why two breakers, not why would I tie them.

Which begs the question, is it okay to have them on the same 120amp breaker even though the manufacturer reccos separate (dryer IS gas).

If you have two circuits on the same yoke the breaker handles must be tied (or use 2 pole breaker) regardless of whether it is a multiwire branch circuit or not.
Would you suggest using a shared neutral with 12/3? Or if I went this route, so I just use 12/2 for both and treat them as if they are on different receptacles?

Thanks all for the help.

Normally only one (duplex) receptacle on one breaker is used for the dryer and washer. Just run a 20 amp circuit. It should be fine. Just as long as the amps of the dryer and washer added together is 16 amps or less you should be fine. Or is this a dryer with special features like steam.

Or as others suggested just run a multiwire circuit.

Pros, if he runs a 20 amp multi wire circuit will the one receptacle rule apply requiring a NEMA 5-20R?

My opinion is yes, the split wired duplex receptacle will have to be rated at 20 amps.

Now that I'm thinking about this, you may want to use 2 20A single receptacles as some washers and dryers have angled plugs. What I would personally do is run 12/3 on a 2 pole 20a breaker, into a 2 gang box feeding 2 single receptacles. Use a gfci breaker if gfci protection is required.
