I want to make a laundry shack for my renters. I plan on using 3 driers, and 3 washing machines, and some fans and lights. There is a little less than a 100 foot distance from the breaker box to the laundry shack.

I have a few questions that I am having difficulty researching. What gauge wire is recommended? Would we use a 100 amp breaker in the main breaker panel, and 4 30 amp breakers (1 for each dryers, and 1 to cover the 3 washing machines and lights and fan), and a in the shack panel?

Keep in mind I am new to electrical wiring, and I am unsure of the laws and regulations involved with such a structure, so I would like to know about this too. I am located in Houston, Texas, by the way.

Why the fuck would a dryer need a 30 amp breaker?

Put each washer / dryer pair on a 20 amp breaker with 12 gauge wire, and the lights and fan on a 15 amp breaker with 14 gauge wire.

I read from googling "dryer amp draw" that they draw 22-24 amps on average. The washing machine draws 10 supposedly, so it would trip the 30, right?

The dryer we have currently is a few towns away, so I cant see the specifics right now, I used the first page of google to conclude a 30 amp breaker is standard.

Jesus wept! Find the fucking specs of the make and model washers/dryers you have by using that Google thing!

And where the fuck are you that you can do your own electrical for commercial use?

Im assuming electric dryer? Shouldnt you have various fossil fuels lingering around all around you down in texas? Do natural gas if you can. Way cheaper and better.

If not, electric dryers are 240V. Each need a 30A double pole breaker. Washers are 120V and (my new LG) is 10A so 15A single pole breaker dedicated for each. These type of appliances usually want dedicated breakers and the advantage for you is if a breaker trips, it doesnt kill them all.

Add another 15A for lights and exhaust, makeup air fan. Remember, each of those dryers is like an exhaust fan so you will need to replace some of that air or your building will be in a decently strong negative pressure.

you will need more than 100A breaker in the main panel. see if you can get a 150A for your panel

30A needs 10ga
15A needs 14ga
150A for that long distance will probably end up being 4/0ga (check local codes)

Agreed, although weirdly the US can have natural gas as quite expensive. LPG is also an option.

Dont do it bro. Cram them in the apartments on payments. Jack rent $50-$100 more than the payments.

Git gud.

Nobody likes communal wash anymore. It's a big deterrant. A few arcade games and vending machines are cool.

Join a loacal REIA or other real estate investing group. They'll tell you the same and it's great for connections.

Oh, you are probably thinking on an electric dryer... Natural gas is almost always cheaper for heating stuff.

its faggots like this that ruin this board with their dont know shit knowledge. if you want to do it RIGHT read the manual it will tell you what is REQUIRED for proper electrical hookup. driers need the proper breaker and be on a DEDICATED CIRCUIT not on a circuit with the washer or lights or anything. it should have its own breaker and be the only device attached to it. on standard drier installs 30 amp is common since as others stated driers can draw over 20+ amps... 30 would protect it and you would use 10 gauge wire for a 30 amp circuit.

fuck me american electrical code is scary.
is that what it says in the handbook?
30A -> 10 gauge.
no calculations, no installation method, no length to worry about, just
30A -> 10 gauge is fine.
well fuck me up the asshole i guess.

the only appliance that normal people put on a dedicated circuit is a freezer. i genuinely feel bad for you that your voltage sucks so hard.

That's what it says in the NEC, yes.

>no calculations, no installation method, no length to worry about, just

There are additional considerations beyond the ampacity table. In most typical installations, however, yes, the table is the rule. There's a shitton of safety factor build in, even before temperature/fill factors.

>the only appliance that normal people put on a dedicated circuit is a freezer

...a freezer? What the fuck? Freezers draw jack shit for current, generally nowhere near a typical heating element of any kind. Where are you that they need to be on their own circuit?

Most of north america is like that. That way if something on the circuit trips it won't kill the power to the freezer and wreck your food. I'm pretty sure fridges have to be on their own circuit too. This is why 120v and lots of separate circuits if far superior to single phase 240.

your right something doesn't look correct to me either, but I think they are using an ATS as the 1st point of disconnect and the meter is on the backside in hot sequence.
