wiring two pumps

[mhb69]

Hi All, I'm in Sydney and I just received two 240V Chugger pumps from the states and am ready to connect them up. But before I do that, I thought I'd just make sure I'm doing things correctly. I have a single power feed (connected to a GFI switch) coming into a 2-gang switch box (waterproof). I've attached my version of a wiring diagram (an electrician I am not). The brown wire is hot and connects to the common on switch1 and a pigtail connects to the common on switch2. The neutral (blue wire) connects to the Loop terminal (which isn't connected to anything -- from what I understand it's just a spare terminal for the neutral). The hot wire coming from the pump connects to terminal '1', which is the pole for the switch.

I believe that I have this diagrammed up correctly, but I'd appreciate informed feedback/suggestions.

Cheers,

Did you attach the diagram? I don't see it on the mobile version. I'm having a bit of trouble following your description.

 

[mhb69]

Not sure why the attachment isn't appearing on mobile devices. I can see it on my laptop, but not my iPad. Anyway, here is the diagram: http://flic.kr/ps/2tf9L6

You're right; my description won't make any sense on its own. Hopefully it does with the diagram?

Cheers

I don't necessarily see a problem with the circuit as long as you are 100% certain that the terminal the neutral is connected to is completely isolated from the common terminal as you have described. Is the switch a single pole single throw or is it a single pole double throw? If its a 1P1T then you should be fine. If its 1P2T, you will end up with a shorted neutral.

Thanks a bunch tyzippers. The switches here in OZ are set up to be either single throw or double throw (see here: http://archive.siliconchip.com.au/cms/A_110732/article.html ), but the loop terminal is always isolated.

Thanks again!

I've had a few beers, but I gotta ask; when using 220v do you have a switching leg or do you switch both legs? And what happens if it shorts? Do you have an earth ground?

 

[mhb69]

umm, not an electrician, but I'm guessing you think I'm combining two 110s to get 220? Here in OZ everything is 220V (just like 110 in the states). we're not combining two 110s to get 220.

 

[mikescooling]

I'm an HVAC man is your 220 different than mine?

 

[mhb69]

I believe so. our mains power is 230V (+/- 10%) and it is 50Hz. The new chugger pumps are 230V (50/60 Hz).

 

[mikescooling]

We swing 220-240. and are 60Hz/. I don't know what difference that makes.

 

[mhb69]

perhaps I misunderstood your original question. Is there anything in the diagram that I included that is problematic? And if so, what exactly? I'm not an electrician, so the more specific you can be the more useful it will be to me.

Thanks a bunch!

Cheers,

Mike, he's in Australia. Their electricity is a bit different than ours. I think this may be the disconnect?

They have a single phase of 220v and a neutral, just like we have a single phase of 115v plus neutral here....for our 230v we combine two legs of 115v....they don't have 115 unless they use some sort of transformer I think....

mhb69...you should be just fine with the way you have it setup.

Finally got a chance to plug 'em in and everything worked perfectly. Thanks for all your help!

Glad it worked for you!

I have the same issue, except that I am wiring two 115v pumps from a gcfi to two single throw switches. The wiring in the diagram does not work, because of the extra connection to center, which is not present in the single throw switches. Any help for a guy in the States?

If your single-pole/single-throw switches only have two wiring poles:

- wire the GFI LOAD side hot/black wire to one pole on each switch
- wire each pump's black/hot wire to the other pole on its switch
- tie the pump neutral/white wires together and connect to the GFI LOAD side neutral/white wire
- connect all of the green/safety wires together and back to your line cord.

That'll work...

Cheers!

Day_trippr - that was it! Thanks for the help.

Thought we lost you there

Glad it worked out...
