Can pool pump & swg be placed on same circuit as well water pump

I am in the midst of building my 1st pool, in Honduras.
I will be installing the pump, filter & SWG in a pump house I have, that currently houses my 1 hp water pressure pump.
I am a novice when it comes to electricity, so want to know if I can place the pool pump on the same circuit as the pressure pump. Both will be 110v, 1HP. I am currently running 14 gauge cable from a 30 amp breaker, to a sub panel in the pump house.

Or should the pumps be on separate breaker circuits?

Finally, would I be better running 220V to both pumps (they are both capable of 110 or 220)

Thanks in advance for any advice you can provide!

Mc,

I'm pretty sure you must use 10 gauge wire for a 30 amps circuit...

Otherwise, I see no reason you can't use one circuit to run all three.. They would all need to GFCI protected.

That said, I would not do that.. I like to put things on separate breakers so that if the breaker pops, I know which load is at fault.

And... the SWCG's power supply should never get voltage if the pump is off. So, if you plan to have a timer for your single speed pump, your SWCG must be powered by the same timer.

Thanks,

Jim R.

MC,

If it were me I'd go with 220 v if it's available at your house. I'm assuming by water pressure pump you mean well pump. Many (most) well pump motors can be wired for either 110 or 220 v. Wire sizes will be smaller for 220v and most pool equipment is supplied to work for either but is usually 220 v by default. From a capacity perspective there's no reason you can't run 2 pumps on one circuit so long as it has adequate capacity but in the US, pool pump motors require a separate GFCI circuit by code. I have no idea what's appropriate for Honduras.

Whatever your choice on wiring the pump(s) it's very important to follow Jim's recommendation to ensure you can't accidentally or through a single failure operate your swg power with no flow. Even though some swg manufacturers allow this using only the included flow switch as protection I wouldn't do it. Many TFP experts also recommend against this since the consequence of a single failure can be an explosion.

I hope this helps.

Thanks all for your input!
I've decided to leave our well pump on it's existing 110V circuit from the main house power supply, and add a separate 110V circuit (using some 10 ga. cable I have), so both pumps will be on separate breakers at the sub-panel. Also, the pool pump will be on an intermatic surge protector.
After the input received here and doing some more reading on the internet, running either or both at 220V did not warrant the effort.
And I am going to wire the pool pump & swg to the timer so that both go on and off together.
Again, thanks all for your replies
