A question for electricians ?

[Tashyboy]

I have managed to snaffle a industrial power wash from work which requires water and electricity supply to the same said machine.

as it happens the one we have at work is identical and broke down. A guy came out from another company to do a service on the machine. I mentioned I had one at home and he said. Yes it will run on normal mains water, but it is a "phase three motor" which runs off 415 volt so is no good to run off normal household electricity. An electrician at work said he could couple it up.

So so who is right. The guy said he would take it off my hands for £100 so I deffo have not lost owt but I would sooner have the washer working. Any advice greatly appreciated.

Should give you a clue.

Three phase motor maybe?
I think it can be done but the long term health of the washer may not be good as the motor won't be running at full speed = extra heat = not good.
I'll be happy to be proved wrong and see a good outcome for this though :thup:

Ah cheating

If you're going to go to the bother of snaffling something, at least snaffle something that works and wont cost much to get working.

It is possible but it'll cost you and 3phase is a whole different ball game from a safety prospective.

I'd stay well clear in a domestic environment.

Without checking the cost of inverters I am guessing it could get expensive. If you look at the plug on it you will see that it has 4 pins, 3 Phase lines and a neutral. You can't start cowboying it and connecting all 3 to one and use a standard 3 pin domestic plug.

It may be possible to get the motor re-wired, or it may already have the capacity to be changed to a single phase motor, but you would need to get the operators manual for the machine to check I this. If you do have that then it will have the wiring diagrams to show how to hook it up in single phase, so you can work it off the domestic supply, but I WOULDN'T advise doing this yourself.

Bloody hell there's not a single picturesque in that lot.

looks like am screwed 😫 an that was part of my redundo plan, mat sell it and buy a beast that's portable.

I prefer to call it research………

 

[Tashyboy]

Nah then, Tashyboy fully understands that no means no. Especially when told by a expert. there is no grey area no means no.

However?

Sunday has been a day of doin a million catch up jobs, which involved goin in and out of the garage a million times. And summ at was buggin me. Me pit electrician was sayin you can use that power wash, but the expert was sayin you can't. Why did both contradict one another?
I have at home the operators and maintenance manual for a WMA 13/100 (my pressure washer) static high pressure cleaner which shows that the voltage is as shown in the book under Technical Data.

WMA model 13-90/100
240V x1
Or
415 x3

Absorbed power 2.2kw

motor power 240V. 2.2 kw
415V. 3.0kw


Bottom line for Tashyboy is what's goin off wi these numbers and where do I stand.

sorry for bangin on but what's happening wi me power wash and the ability to use it at home. pleeeeeeeeeeeeeeeeease.

 

[Beezerk]

Maybe they come in 2 different models then. There will be a plate on the side somewhere which will show the correct model.

 

[shewy]

So the model in question can be fitter with either 3 phase or single phase motors, what you need to check is which one you have, take the plug off and see what wires you have got going to it, live, neutral earth and bingo you have the single phase motor. 3 wires and earth + neutral your buggered.
Another dead giveaway is there will be a capacitor bolted onto a single phase motor.

The plug which is fitted to the machine is a 110 volt plug, which the elect has sourced a socket and cable for the machine.

the guy who said it was 415 volt showed me a 5? Pin plug which he said is for the bigger voltage. But this is deffo different to the one on the machine.

If the ORIGINAL male plug is YELLOW with only 3 pins then its 110 volt unit and you will need a 240 to 110 volt transformer, it's also coloured yellow.
A 3 phase 440 volt unit would have 4 wires/ pins, if a neutral is required then its 5 wires / pins colour RED. A 240 unit would have a 3 wire /pin BLUE male plug.

Sounds dodgy as owt to me mate, a 110V plug on a 415V machine? Cowboy central here we come...

At the pit all of the electrical gear is required to run at 110V so it would make sense

I reread your first post , in some appliances like cookers /hobs links must be fitted to bridge the L 1 2 3 connections to enable a 240 v supply to be used, in low KW load units.
Can you post a picture of the units terminal box connections.

williamalex. Am off on a matchplay comp in 30 mins against an excellent 12 handicapper on his course. So I won't be back til late, then off to work on nights.
I will see me elect mate tonight and ask him a few questions and aske him were the unit terminal box connections are.

cheers boys.
