Old thread but maybe you'll see my question.
When using a relay board to operate a SWCG and Booster Pump they are supplied with power from the supply lines for the pump, right?
If that's the case isn't the current requirement increased significantly on the supply lines for the pump? Can existing wiring/breaker handle the additional load? At this time, I'm not certain of the draw from booster pump and salt cell, nor do I know the breaker rating. Current pool pump is 1.5hp Pac-Fab 220v.
I'm just trying to sort out if adding a relay to control booster and SWG is worth it, or keep using timers and keep new pump separate.
Intelleflo3 VSF is what I'm getting.

No.

You need to wire jumpers from the p[uimp power to any relay you want to share the power with.

Depends what device you are sharing g power with. SWG are low amps. Around 2 amps at 240V.

Can existing wiring/breaker handle the additional load?

Depends

Booster needs its own power feed.

Current pool pump is 1.5hp Pac-Fab 220v.

You should have separate breakers now for pump and booster. I don’t see the problem.

Probably because I'm doing a poor job of asking. I don't have the new pump yet.

For the booster pump would I take the wiring going from the current timer to the booster and connect booster wiring to relay board in new pump? I'm guessing the wiring is 12g. The manual makes it look that way, but then I started thinking about the load of booster, pool pump and SWG on one breaker.
 
show me what you have now and the breakers.

Booster CB goes to relay LINE connections. You can use timer box as a junction box and splice the booster wires together.

Then you connect booster pump with new wire to relay LOAD connections.

You will need some electrical rewiring for your new VS pump with the relay board.
