Splitting packaged spa wiring components

Those are just reducing washers.... They are spray foaming the walls and I wanted something to hold the connectors flush at the wall; I won't set the disconnects until they paint.

Neutrals are in the trough in the ceiling and passing on to the spa.

Disconnects are going to sit right here on this corner. They're within sight and about 8' from the corner of where the spa will sit.

I'm not sure what the customer paid; I was assuming closer to $25k but just my guess.

Gotcha. Was thinking that the load side of the disco was going straight to the spa. Looks good. What did you use to cut the oval holes in the studs to get the RPVC thru?

I take it those swim spas must have a pretty powerful pump to provide a current to swim into - how many amps does that bad boy pull if everything is running?

Thanks for the pics.

eta: what are the green cables in pic #1, comm cable?

Hole saw and chisel haha.....

Yeh the PVC goes down out of the foundation wall and underneath the slab to come up inside of the spa.

The spa is 40A 240v and the "pool" is 50A 240v.

I believe the pool side has 3 pumps and a heat pack, and the spa has 2 pumps and a heat pack.

That wire hanging is the grounding wires in the trough. The cover was open in the pic.

Can't say I have ever used one, but kind of makes some sense since less components are needed to be stocked for assembly- as in they probably use the same 120 volt logic components as they do in other GFCI breakers, this would mean you do need a supply neutral even though there is no load neutral for it to work correctly though.

Here is the QO260GFI I had ordered for this project .....no neutral connection on breaker

Just a #10 neutral pigtail.


And here is the QO240GFI with a neutral connection, and full sized pigtail

It apparently needs a neutral for the GFCI monitoring circuitry, isn't all that clear in the catalog though.

That, and I assumed it uses it as a reference point to ground when checking current imbalances between lines. Idk...

It don't care about ground reference when it comes to imbalance monitoring. What passes through one direction of the CT must come back the other direction thru the CT whether it is a grounded conductor or not. Just like clamping a ammeter around all conductors of a circuit should display a net of zero if nothing is flowing through alternate routes.

It's always a bummer when the pipes wont turn out. Not that you'd ever have to, but, if you did, the flex in the wall makes pulling things in or out in the future more difficult and the flex fittings inside the wall usually seem to be the first thing to let go.

Would've been nice but wall was just a little too narrow.....

The guy running the pipe came and asked me for a greenfield 90

The fender washers are a nice touch.
I use the same thing as a trim ring when I flex out through the insulation on metal buildings to get to the wall packs.

Reducing washers I meant.

When that says 'for reference' it means the connections will be similar but you have to check.

It does not mean for electrical voltage reference.

As kwired pointed out, GFCIs do not need a reference to function.

 

[peterlarsen.suntec]

Yep

The notes and warnings there are to make sure you know what the function of the terminal is that you are landing a conductor on. You can make essentially the same mistake at the connection at the distribution panel where there is no GFCI and have same result, and it has nothing to do with the functionality of a GFCI.

 

[peterlarsen.suntec]

Yep, agreed.
