Laundry Circuits

I have a customer who wants to run two circuits for an existing laundry closet that is located in a finished breezeway which is on a slab. I need to run the circuits across the unfinished basement and poke through to the laundry closet. They want two circuits in there due to the gas dryer, iron, washer, and rechargeable vacuum. The gas dryer is already installed, so working behind it will be a pain. In any case, would you just emt behind the washer and dryer on the finished Sheetrock wall? Sketch attached


Separate question. If you’re installing a subpanel that has two factory installed ground bars the housing of the panel is sufficient, you don’t need to add a jumper between them, correct?

1) EMT is permitted as long as the customer doesn't mind the aesthetic.
2) Listed EGC bar installed in a panel to the metal enclosure with the provided mounting screws does not require a bonding jumper.

Would you use EMT, or would you do something else?

I thought I could also run across the bottom of the wall in emt to a surface mounted 4” square then snake up the bay for receptacles.
I’m just looking for the easiest way to do this

Yes your method is fine. Sounds like the EMT wouldn't even be very visible. The easiest way is to surface mount the EMT and forget snaking the wall but that may only be acceptable if the customer doesn't mind seeing EMT run up the wall.
 
I’m doing this job this weekend. As stated earlier I’m going to run two circuits to this laundry area one near dryer, and one near the washer. They both can be duplex receptacles, correct?

Yes.
 
They don't really need two, but fine if they are paying for it. I have two washers and two gas dryers all sharing one 20A circuit. I would have run two, but previous owners only ran one. At least there is no iron in the mix, but the 20A has never tripped.

Dont forget AFCI and GFCI protection. A dual function AFCI breaker would be easiest if they make those for the panel.
 
I did this project last weekend in emt, and it came out nice. The emt is mostly behind the gas dryer. As the dryer was being pushed back I was wondering if I should of built something like a barrier out of plywood (It’s rental property, and hidden behind the dryer). between the emt and the dryer to protect the emt. Do you think the emt needs to be protected from damage (Dryer hitting it), or even from the heat of the flexible vent hose if gets pressed against it? I was curious if I should do anything further. This is for a friend, so I’m not making much anyway
 
That’s what I wanted to confirm, is emt alone good enough in this location?

One more crazy question. Each circuit has its own conduit, so there are only two current carrying conductors (#12 THHN Solid) in each conduit. Since the conduits are behind the dryer did I have to make temperature adjustments? One circuit is a gas dryer, and the other is the washer and a rechargeable vacuum, so not much load on each.

The emt is fine. The outside of the dryer doesn't get hot enough to worry about any ampacity adjustments.
