Spray booth wiring 3phase to single phase

[Tommy mc]

Hi guys ,

I bought a booth for in our workshop the issue is we only have single phase ...phase converter would coat around £1000 so was looking at swapping the motors out?

i can get same spec motors in single phase but what would need done to the controll panel ? just asking incase someone has been through this before .

burner , lights ,actuators are all 240v on booth so just motors

Many thanks

Tommy

Do I take it that you did not buy it new from a proper supplier? If you had, you could might well be able to send it back and have it swapped for a single-phase version.

I presume from what you're asking that your supply would be adequate for an equivalent single phase motor? What is the motor's rating?

Kind Regards, John

Thanks for the reply.

We got it second hand as can't afford new

We have 63amp main breaker that we will have someone come to wire in once booth is up.

The motors are 2800 rpm 3hp items X2
My question is what would need altered in the control panel pictured. ..as the main isolator was 3 phase set up ...do we have to change contactor etc ..

Thanks again

Supply was wires coming into bottom of isolator iirc .

Most / all of the 3p wiring.

do we have to change contactor etc ..

Possibly, depends on what rating they are, same for the two overload relays.

This is a non-trivial amount of work, and totally outside the scope of this forum.
You need to get someone in to do this for you.
It is not just a case of swapping a couple of wires.

The phase converter may be a cheaper option.

Thanks flameport !

When you say get someone in would this be booth person or an electrician ?

An electrician, and preferably not one whose only/main experience was of domestic work.

When you buy the new motors ensure they are suitable for use in the environment of a spray booth. The fumes from the material sprayed are likely to be inflammable and any spark from a motor could ignite the fumes and cause if not an explosion then a flash fire.

They are outside airstream driven by belt thanks

I presume you are talking about a spray booth that is erected in a workshop, if so then Bernard's recommendations still apply. This is quite a specialised job where not only electrical but also building & fire regulations apply so you really need specialist help.
