New 2 speed Motor Question

[ajw22]

The previous owner who had the pool installed was going for a real party atmosphere and i'm not quite sure what is going on with the panel. There is an attached spa and pool propane heater that is connected to the panel as well.

You have 8 circuit breakers in the panel.

Two CBs are 240V and 6 are 120 volt.

Can you list what devices are powered by each CB?

I confirmed that aux 5 doesn't have anything going to it but has the connector going from it to the board. Would i be able to swap out that relay that isn't being used with the potentially bad one that you id'd? Also above it mentions solid copper, but looking at the wire in the panel in the light right now it is stranded.

Answering the earlier question about how many CB's i have in this panel. I traced it all out, the top two cbs go to the pool/spa heater, the next bottom two with the bracket are the filter pump and the water feature pump, and on the other side is the pool/spa lights, breaker for the panel it self, gfci, and a bbq that was never installed.
The 2 240V are for the filter pump and the water feature pump.

AUX 5 is not being used, so you can unplug the 24 VDC coil at AUX 2 and AUX 5 and plug AUX 2 coil into AUX 5 coil and plug the two speed relay into AUX 2.

You can use the AUX 5 relay to replace the Filter Relay if it is bad.

 

[ajw22]

One 240V CB is 15 amp and the other is 20 amp.

What is attached to each?

Which is the new motor going to?

15 amp uses 14 gauge wire.

20 amp uses 12 gauge wire.

Solid copper is preferred but stranded works fine.

Confirm the wire gauge of the burnt wires.

You should get at least one spare relay in case you need it.

You can unplug the Filter Pump relay and plug in the Aux 5 relay to the Filter Pump relay and move the wires, which will make it slightly easier to wire the two speed relay to the filter relay.

That's sort of bad practice, because you are putting relays out of order and someone might get confused.

Or, just move the AUX 5 relay to the Filter Relay position and discard the Filter relay if it is bad and get a new relay.

 

[ajw22]

This CB has three 20 amp circuits. The two outside that are tied together and form a 240V CB and you say power the filter pump.

The two inside 20A CBs can also power 120V circuits. Are they being used?

This setup will cause problems putting in a code compliant GFCI CB for your pump.

 

[talbritt]

the 15 amp 240 is connected to the heater. and the 20 amp 240 is connected to both pumps. I would use the existing CB and wiring for the old pump with the new addition of the common wire running to the relay.

 

[ajw22]

Check the amp ratings on the motor data plates of your two pump and confirm they add up to 16 amps or less which is the maximum load for a 20 amp CB.

 

[talbritt]

Here are some up close pictures of the breaker and the relays the wiring goes to. The yellow wire is coming from the middle tied together circuit and run to the relay that controls the filter pump. the outside black wires run from the CB to the Aux 1 Relay(water feature)

Then the two pumps are running on separate 20 amp circuits.

Are the inner two CBs forming the 240V filter pump circuit have the breakers tied together such that if one side trips both trip?

 

[talbritt]

Do you mean the plate on the two speed? or the plate on both the new motor and the existing water feature? Above is the picture of the Water Feature motor plate.

Yes the middle two are tied together with a little metal bar and then the outer two are tied together with that bracket.

To bring your panel code compliant with 240 V GFCI CBs you need to change your heater to run on 120 volts and move the circuit to the unused BBQ CB.

Then you can put two 240V GFCI CBs on the left side for your two pumps.

Which circuit is your spa blower powered from?

 

[ajw22]

View attachment 470072Do you mean the plate on the two speed? or the plate on both the new motor and the existing water feature? Above is the picture of the Water Feature motor plate.

Never mind since we now see the pumps are on separate circuits.

 

[ajw22]

I traced it all out, the top two cbs go to the pool/spa heater, the next bottom two with the bracket are the filter pump and the water feature pump, and on the other side is the pool/spa lights, breaker for the panel it self, gfci, and a bbq that was never installed.

Spa blower circuit?

 

[talbritt]

Then you can put two 240V GFCI CBs on the left side for your two pumps.

Which circuit is your spa blower powered from?

the spa blower is on a 15amp CB below the panel CB on the right side. The pool/spa lights and the GFCI outlet are on the 20 amp below.

 

[ajw22]

the spa blower is on a 15amp CB below the panel CB on the right side. The pool/spa lights and the GFCI outlet are on the 20 amp below.

So from the top right CB you have:

• Panel CB - 15 amp
• Spa Blower - 15 amp
• Pool lights and GFCI outlet - 20 amp GFCI CB
• Unused 20 amp

And code requires gas heaters to be on a GFCI CB.

What model heater do you have?

 

[talbritt]

Its a Jandy LX 400.

 

[ajw22]

Its a Jandy LX 400.

Thinking about it, you can leave your heater as 240V and connect it to your filter pump relay on the same LOAD screws as your pump. That is what the heater installation manual recommends anyway.

That makes installing GFCI CBs for the pumps simpler.
