Can I use a submersible pump 220v Canada in Asia 220v?

[YN]

I want to use a submersible pump that I bought in Canada 230 volts 60
hz with 2 wires (one red and one black) plus a green ground, in the
Philippines where the 220 volts is delivered with only one wire
(black). It should work, same voltage but how to connect?

Now I ask, how can the Philipines 220V ac be supplied by a single
wire? Nowhere on earth would a single phase with earth return circuit
be allowed for ac mains supply voltages. There must be a LINE wire
(active phase) and a separate NEUTRAL return wire.

I'd love to know how the Philipines have managed to deliver electricity down one
wire !

Can you elaborate slightly ?

yes the phillipines has 240v ac 60 cyles as distribution for all to use. I am sorry to say but there is no code about wireing any house or actualy anything at all. It is not uncommon to see 240 just 6" off te ground for distribution to sheds or what they call it NIPA HUTS. So don't worry about the color code electrons or holes do not know about polarity. If by any chance it burn up don't worry those people will rewire it t for you for a song. And further more I can purchase a motor there a hell of a lot cheaper then here like 5 to 1. all water is runon motor tere is no city water. and thee is two wire delivery and you are mistaken tie the green to earth possibly a gnd splike.

You kids have it so EASY. Why, when we were young, our AC power came
on just one wire!

I'm still wondering how they measure the voltage.

Yeah, don't we

I'm not what you would call a "kid" though - been around a while.

Of course, power companies do construct rural power distribution
systems using single wire earth return (SWER) to save on conductors.
Consumers are isolated from that system by a distribution transformer
which converts it to a 2 wire isolated supply.

Any idea how the feeders are set up at the substation? I would guess
the substations would only receive one phase, but do they stick the
neutral to ground?

Sorry, I'm not a specialist. The electric company in the Philippines
provides with 2 wires, one black and one neutral. My pump from Canada
comes with 3 wires, one black, one red, and one green. The pump is 230
v, 60 hz, 1 ph. On my meter in the Philippines it is 220 v, 60 hz, 1
phase. I think I should connect the green from the pump with the white
neutral. But what should i do with the black and red from the pump?
Connect only the black from the pump to the black line wire and no
connection to the red. Or connect the red and the black from the pump
to the single black line wire? Please help, I don't want to damage
this expensive pump. Thanks

In North America, green is used for ground AKA earth. When the two
non-ground wires are red and black, I believe black is neutral and red
is "hot." All this would mean that green should be connected to a good
ground, your pump's red wire to the electric company's black, and your
pump's black wire to the electric company's white. However, I think
you should look for more confirmation and not just go with my say-so,
especially as it's an expensive pump.

So long as the voltage between the two wires is within the pump's
range of operating voltages, you won't damage the pump, but electrical
safety might be a issue.

The earth/ground connection is there to short the power in the event that
any exposed conductor becomes live. Even if the pump has no exposed metal,
the water in which it is submersed could become live if the pump were to
leak.

I strongly suggest asking someone familiar with the local electricity
system about grounding. If in doubt, add an isolating transformer and a
residual current device (RCD, aka ELCB, RCCB, GFCI, ALCI), i.e.:

+-------+
o-- || -------| |----o L (Red)
\ || / | |
/ || \ | |
\ || / | RCD |
/ || \ | |
\ || / | |
/ || \ | |
o-- || ---+---| |----o N (Black)
| +-------+

+----------------o E (Green)

Has to be single phase - that's why it is called SWER, and yes, N is
earthed at substation.

It is not usual to feed a submersible pump via an RCD. The pump should
be fed using a circuit breaker with adjustable current and thermal
overload tripping.

Here is a typical instruction manual for submersible pumps (both 3 ph
and 1 ph) as used in Australia on 240V MEN system.

Note that the first wiring diagrams should be headed Three Phase and
not Single Phase (publisher oversight). The pdf contains tables for
current for various size motors so that you can select and set a
suitable circuit breaker.

Boo-boo........

P.4 shows 3 wire single phase pumps. The additional wires are to
connect the start capacitor in the motor control unit.

You believe. Perhaps you shouldn't answer questions relating to 240V
electricity until you *know*. Especially when what you believe is totally
incorrect, and dangerously so.

In North American power wiring, black is *never* neutral. It is *always* hot.
Neutral is *always* either white or gray. When black and red wires are
present, typically they are *both* hot with a 240V potential between them.

All this would mean that green should be connected to a good
ground, your pump's red wire to the electric company's black, and your
pump's black wire to the electric company's white. However, I think

Especially as you don't know what you're talking about.

No. The green wire should be connected to earth ground.

But what should i do with the black and red from the pump?

Connect one to black and the other to white. Doesn't matter which way.

Your Canadian pump has two hots (black and red), a ground (green), and no
neutral. In North American power distribution - same is true in Canada, U.S.,
and (to the best of my knowledge) Mexico - uses a three-wire system in
which 240V is supplied from a transformer with a center tap which is strapped
to ground. The two hot conductors have a 240V potential between them - the
black and red wired to your pump - and a 120V potential to neutral and to
earth ground.

Power distribution in the Phillipines - from your description; better consult
a local electrician to be sure - is evidently distributed as 240V over two
wires: one neutral which is/should be tied to earth ground, and one hot with a
240V potential to neutral.

As long as the two power supply conductors that you're hooking the pump up to
have a 240V potential between them, the pump should be fine.

Connect only the black from the pump to the black line wire and no
connection to the red.

Pump won't run, since there's no completed circuit.

Or connect the red and the black from the pump
to the single black line wire?

Pump won't run, since there's no completed circuit.

Since the pump was designed to be operated at 240V anyway, that shouldn't be a
concern.

If the red and black (wires on the pump) are supposed to have 230VAC
across them, then my instructions were correct. What makes you think
the Philippines is supplying split-phase power? More importantly, why
do you think it makes a difference?

Boy, that advice sounds familiar!

Back up and re-read. I was correcting your erroneous and dangerous statement
that black is neutral in North American power wiring. It's not. Ever.

I was giving advice to a guy in the Philippines, and I'd qualified my
remark about red vs. black. My remark may have been technically wrong,
but your advice to the guy I was advising was IDENTICAL.

Thanks for the info about NA power wiring, though. Any idea whether
gray, pink, or flourescent orange should be phase A, B, or C?
