220V for a pressure washer?

[weatherby460]

I need to install an outlet for a 220 Volt pressure washer.

Is 10-2 wire ok to use with a 30 amp breaker at a 40'length? Also, does anyone know what would be the type of outlet configuration?

I don't have the washer yet, but wanted to get it pre wired this weekend.

Thanks

Yeah thats fine,cant say about outlet because you have to match up the plug

We/you need to know the specs for the pressure washer and also find out what plug is on the end of it now.

Before you wire a circuit you need to know the specs of the equipment.

Is this designed as a portable or fixed piece of equipment? Portable pressure washers requiring 240 VAC are not too common. What is the pump motor HP? Does this have a heating element per chance?

Its a smaller version of this made by the same company. It is 2200 psi at 4 gpm. I know its 220v, and the salesguy said to install a 30amp breaker.

 

[justsam]

To deliver 2000PSI at 4GPM will take at least a 5 HP motor. You definitely need to confirm the plug termination. I suspect it will be a typical 240 VAC welder plug and you will need the matching receptacle.

I'd ask for them to send you the specs for the motor NAME PLATE. I just looked up the washer pictured, I know you said this one is smaller, but the one pictured is 10HP

I'd be inclined to agree with justsam

If the salesman said a 30 amp circuit... I'd change plugs on the pressure washer, go with a 50 amp circuit, so you can also run your welder on the same outlets.

I put 6-50's in my shop... and never regretted it.

I like twist lock plugs and receptacles, since no one will ever plug it into the wrong socket, and no one is ever going to ask to borrow it. I put a 110 twist lock plug on my battery charger, and no one has ever asked to borrow it after seeing the plug configuration.

The salesman said 30a and we already can't make it a couple posts without doing something different,
Use a 10 wire and a 30 @ recept. The machine is designed to be on the correct circuit in this case, will come with a 30a end and this is not a place for the end user to start calculations,,, yes, many come with 5 up but they are made this way and the rest of the internals on the machine are sized for short circuit for 30. They do not have extra protection except for thermal on blower motor if this is a hot unit and are dependant on being wired to the correct circuit.
Same for a welder with factory cord, machine limited to 50a circuit.

They normally come with a 6-30-P, as the man said above you have to match the plug and never cut an outlet off a machine to wire a larger plug on.

If its more than 3HP then it will need to be hardwired unless a plug and recepticle that is rated for more than the standard ~3hp is used...

Yes because salesman NEVER get anything wrong!

If I run the 10/2 wire...I should at least be ok with that?

It really depends on the hp rating of the motor.

If its 10hp then no 10/2 is way too small

 

[sstec]

I see the spec as 1= single phase / 220VAC / 44 amps , now take that by the length of your wire run. that will give you the load amps for wire size.

Its a smaller version. Mine has a 5 hp motor and came factory wired with 30A and calls for a 30A breaker, never tripped it.

 

[koditten]

Mine is on #10 wire as well. 30A breaker, no issues. I believe mine is a 3 hp motor.

Usually electric Pressure washers are lower HP than gassers. I'm thinking a 3hp is equal to 4 or 5 gas.

I'm really having a hard time believing that the motor is a 10 hp.

 

[sberry]

The one in the link is 10, that's not the one he is getting. This has made it confusing as well as the fact that from the looks of it here no one has ever actually installed one or read a manual.

 

[sberry]

I forget what listing, doesn't seem it was UL but,, if it is assembled and comes ready made with a cord follow instructions and put it on mfg listed circuit. I doubt it will suggest getting other opinions from the internet.
1 electric for 2 hp gas in this case

 

[justsam]

As has been suggested by others, wait until you have the unit, or the spec. for the model you have purchased.

Also as suggested I would not in any way change what is on the unit, since I suspect it is an assembly and suspect power cord will fall under UL62, if maintained as an assembly.

Assuming the 30 Amp requirement, the 10ga you have provided is fine, just a question of what receptacle to terminate in. I would be curious what the manufacturer has used for this application.

Alkota uses 6-30 on thier comparable model.
