Any electricians in the house?

My swimming pool pump needs replacing. Its a Jazuzzi pump and its rated for 230/115v. Now it has two (2) breakers in the fuse panel. Does that mean the installing electrician wired it to run a 230v?

Reason for asking is I have a chance of a deal on a replacement which is rated for 208/460v and I don't want to bring an electrician in.
 
208/460V is USA 3 phase industrial. You can't use it.

You have 2 different 3 phase's there. It's 120/208 or 277/460. There is no such thing as 208/460.
 
Wasn't saying they're the same, only that the voltages he listed are USA.
 
The label on the pump reads 208-230/460v

I cant see anywhere on the label where it says if its single or 3 phase. It's a AD Smith motor model number 137929 if that helps anyone.
 
I just found out its 3 phase so is unsuitable. Thanks very much to everyone who offered help here. Appreciated.
 
There are ways of getting 3 phase to work on single and ways to match voltages but by the time you're through the engineering and special drives an electrician would be cheap.

There is a reason the 208/460 is a deal. No one in their right mind wants it.

Some pump motors are specially wound. I wasted a day trying to get one to do something it was never going to do.
 
After all that I just stripped the pump unit down, cleaned the impeller out and it's woring fine now.

Most 3 phase is 600v here.

I would disagree I work in the automotive industry and most is 230/460 I know the standard is supposed to be 575v but almost all of the equipment is from the US or europe and the plants are on a 460 grid from hydro.

I am a commercial maintenance electrician, I visit at 5-6 commercial properties a day. I have seen 277 at maybe 3-4 properties ever.

That equipment is all from the U.S.
Your customers require transformers to make that equipment work.
 
They would if they were not on a 460 grid. They actually are using transformers on their 575 equipment. Even the places that are on a normal 575 grid have mainly 230/460 equipment and have to use transformers. It is by far the most common motor voltage I see and I do not even stock 575V motors anymore.

Buildings that don't have 600 are old, and rare.
The auto industry only uses that equipment because they have no choice.

Everyone else, 600.

I work for Hydro and there is no 460 grid. As others have stated, 460 is a US standard voltage. If a plant has a big enough power demand, we'd drop 4160 to their sub station and the customer would transform it to whatever voltage they want to use.

I didnt think so but ive never had time to check out where the funky voltages were coming from.
 
I work for a huge construction company and we use tons of 460V... we got transformers all over the place here transforming down to 460... All equipment and tools that require 460 are typically cheaper, taking a transformer site to site works out cheaper.

As an afterthought, if you don't know the answers but want to do the work yourself I wonder about all of the other things the elecrician might know about replacing the motor. Things that you might not know.

Deaths due to electrical faults usually are due to fire, not electrocution. With a pool the danger is drowning caused by a reaction to a shock. Play safe.
