Wiring a jet pump

My Jet pump can be wired 240 or 120. What are the advantages & disadvantages of both. It was wired 120 by the previous owner & I temporarily have it wired 120. Just wondering which would be best when I finally wire it up permanent.

Thanks,
Dan

At 240 it would use less amps, and take up two breaker spaces in the panel. And some believe that 240 is safer to use than 120.

Actually, a motor uses the same energy whether it's wired 240V or 120V. There's no difference. The advantage is that with 240V, you can use smaller wire over longer runs, so that the initial installation is cheaper.

The pump label goes along with what mdtalyor stated about the amps. It's listed as 8.8A & 4.4A. So I guess from the sounds of it there is no real advantages or disadvantages as to the operation of the pump. I guess I'll just run it, 120. Seems to work fine & that's the way it was wired when I bought the house.

Thanks for the help!

That's true. The motor tag shows that the amp draw is twice at 115V than what it is at 240V, but the energy consumption is the same.

120 vs 240

240 is always better. If it's 1/2 hp 120 is OK, but if it's over 1/2 hp 240 volts is better.

He asked for advantages and disadvantages. I gave him that. Energy consumption would be neither since it is the same. Amp draw is different therefore it would be calssed as one or the other...

I'm surprised you read my post as pertaining to energy consumption.
